Subject: [Gambas-user] DatePicker and MessageLabel were disabled in revision
	#3084
Message-ID: <201008010211.32694.gambas@...1...>

Hi,

As the subject said, I have disabled DatePicker and MessageLabel in the 
gb.form component, to see if someone use them.

These controls have problems, especially the DatePicker, and if their creator 
want to fix them, they should tell me. Otherwise they may be removed, or 
rewritten if I have time and someone really needs them.

In the same revision, you can add close buttons to TabStrip tabs, as someone 
asked recently.

Regards,

Hi all, I wrote MessageLabel, if some people use it, I'll fix it,
otherwise just delete it.

Hi Benoit

Is DatePicker, the same as  DateChooser - if so I use it all the time so I'd 
hate to see it deleted.

It's not the same Richard. DataPicker is only present on gambas3 as an user

 I use a custom DatePicker (based on DateChooser) extensively in my
applications in Gambas2, I don't want it to disappear as a control when
I begin migrating to Gambas3, as it saves a lot of code and it's a
handsome control.

So, please do not remove it... ;-)

The DatePicker has many problems, so something must be done!

Message-ID: <1280683284.4461.10.camel@...2406...>

Hi.

1.Objective-----:

*Select an item from a ComboBox control and execute an action on your
Change event

2.Actions-------:

*Load the ComboBox with the elements "1" and "2"

*Create a message in the Change event of the ComboBox:
PRIVATE ComboBox1_Change()
Message("There was a change in the text")
END
*Run the program and select the first item in the ComboBox 


3.Problem--------:

By selecting the first element of the ComboBox does not run the Change
event only when you click the second item. Then, as you can click the
first item.


OS: Ubuntu 9.10
Gambas: 2.21.0
Desktop : Gnome

Mmm. And do not forget that the Change event is raised only if ReadOnly is 
False. Otherwise you must use the Click event.

I need your project and a way to reproduce the bug. At least backtraces, as 
explained in the "Reporting a problem" page on the website.

Note that the Quit instruction is not safe in GUI program. But the Me.Close() 
must not crash at all, or it is a bug!

Sorry, I think this was my fault.
For reasons I don't remember anymore, I had this dialog in the _new() routine.
Put it into Form_Open(), and everything is fine.

Ok, here you have a demo. You should get signal #11 if you abort the dialog.
Move all the code from _new() to Form_Open(), and the crash is gone.

Hi,

As the subject said, I have disabled DatePicker and MessageLabel in the
gb.form component, to see if someone use them.

These controls have problems, especially the DatePicker, and if their
creator want to fix them, they should tell me. Otherwise they may be
removed, or rewritten if I have time and someone really needs them.

In the same revision, you can add close buttons to TabStrip tabs, as
someone asked recently.

Regards,
      

 I use a custom DatePicker (based on DateChooser) extensively in my

I begin migrating to Gambas3, as it saves a lot of code and it's a

So, please do not remove it... ;-)
    

The DatePicker has many problems, so something must be done!

  

   I could not find the code for this widget. Where is located in the (trunk)
   source code?
   And, what are the *many* known problems?

Beside the code that is not very clean, the main problem is the lack of true 
popup mamangement.

I am currently implementing a "ShowPopup" method that allow using a form as a 
popup, and I have written a control named "DateBox" with it, that will replace 
the DatePicker.

At the moment, the problem is GTK+, which has no easy support for popups, so a 
lot of elbow grease and quick & dirty hacks are needed...

Sounds good. Many thanks for it. -the future Datebox :-))

Just for curiosity, this popup is a kind of floating panel in QT4?

If yes, could it be detached from its parent? Well, you know what I
mean: docking panels.

Not at all. "Just" a popup window.

You have to implement your own file dialog with a FileChooser and a 
DirChooser.

The DirChooser has a Root property that constraints the choice to a directory 
and its subdirectories.

Hi.

If I choose to FileChooser or DirChooser, these show me the folder icons to the theme of Gnome.
By using Dialog.SelectDirectory, this shows me the folder icons to the
theme that the user has selected. Is there any way to emulate this
behavior in them?.

Hello,

I use the Gambas-Browser to open an shopping website. There the user can choose his products and order them. T last page of the shop is a status page with all informations in the html-source-code written as comments, which i must read out and save in a mysql database. Is there a way to read out the html-code of the website the gambas webbrowser is currently shown?

Regards

Hey Andreas,

>From what I've read in the documentation there's no text property or any
other way to get the source code of the currently showing webpage in the
webbrowser control... yet; so after a bit of googling this is what I've come
up with.

assuming that your webbrowser control is called Webbrowser1 you can do this

PUBLIC SUB WebBrowser1_Click()
DIM tempHTML AS String
DIM tempLink AS String

tempLink = WebBrowser1.Link
SHELL ("wget -qO- " & tempLink & "|cat") TO tempHTML
PRINT tempHTML
END

This piece of code will retrieve the code of the page you just clicked and
send the html code to the tempHTML variable
It's a bit crude, not 100% tested but I think it works.

I hope this helps till someone else has a better way to do it from within
the webbrowser control

Regards
Dimtris

Hi guys! First of all...I'm new to gambas!
I'm traying to parse a xml from
http://8tracks.com/sets/460486803/play.xml?mix_id=2000
I can get the file with the following code:

' Gambas class file
PUBLIC url AS String

PUBLIC SUB Form_Open()
  DIM reader AS XmlReader
  DIM h AS HttpClient
  DIM buffer AS String
  DIM doc AS XmlDocument
  h = NEW HttpClient AS "h"
  h.URL = "http://8tracks.com/sets/460486803/play.xml?mix_id=2000"
  h.Async = FALSE
  h.Timeout = 60
  h.Get
  IF h.Status < 0 THEN
    PRINT "ERROR"
  ELSE
    ' Success - read the data
    IF Lof(h) THEN READ #h, buffer, Lof(h)
  END IF


The xml file is now in a varaible called "buffer". How can I get it
from xmlread object?

Thanks!

Here is what I could guess by reading the source code of the component:

PdfDocument[Page].Find() will search all occurences of a text into the 
specified page.

Then: PdfDocument[Page].Result.Count returns the number of matches, and 
PdfDocument[Page].Result[Index] a virtual object that represents the rectangle 
surrounding the text in the page.

Maybe if Index = 0, you have the first match?

Is it what you are looking for?

Hi

When I use the controls DirChooser and FileChooser , the icons displayed are those that come in the Gnome theme.



But when I use dialog.Selectdirectory (), the icons shown are the subject of ongoing use, which is Human.



Is there any way to change this behavior in gb.gtk sources?

Regards.

It has nothing to do with gb.gtk and icon theme.

Directory specific icons is a freedesktop standard that the DirChooser control 
does not handle, for simplicity reasons. And because it needs to access a 
directory stored inside a folder making things slower.

Two remarks:

- I may implement that in the future.

- Storing how directories should be viewed inside the directory is a stupid 
design. Why on the heck did they do that? :-( If two users want to see the 
same directory differently, what should we do?

Sorry, didn't see that Benoit had already answered.

But, besides the code: Why do you ask the user (who just has decided) if he
wants to decide? I really hate programs that ask me things like that. If I close
a form by mistake, I open it again.

I think the questions on Form_Close event should be restricted to important
things like possible data loss.

Alas, not for MP3. SDL has no way to guess the length of a MP3 file (funny 
format isn't it?). You just have the time position.

You can get the current position but not the total lenght :)
I used some software that gives infos about MP3s (including total
lenght) in the shell, calling it from GB, to avoid the problem!

I know it's very durty but you can read the tags of the mp3 file. (only 
possibility I found within my small knowledge of programming.
You must have exiftool installed.  I use Ubuntu and exiftool is not 
standard installed.


/'Create tags

The only way I know is a workaround. It works with gb.Qt.

PUBLIC SUB Form_Deactivate()
  
    IF ME.Minimized THEN PRINT "I'm minimized" 
     
END

My goal: Let's have a mobile phone, and I would like to send data (images,
mp3) to the phone, but I don't know how the directory structure of that
certain phone would look like. I would like to have a "Send to:" option
which is present for e.g  in Konqueror, which would enable me to browse the
directory structure and to point to the desired folder. I've tried to create
arrays of Menus, but it isn't possible.
Usually I define a fixed number of submenus inside the subroutine:

PUBLIC SUB Element_Menu()
DIM menu1,menu2,....menuN AS Menu
menu1=NEW Menu(container)
menu1.Text=....
menu1.Action=....

END

And the Actions are global variables of the containing Form, which are
raised inside the subroutine
Action_Activate()

Is there another approach? This all is only for static number of elements.
I'd like to create a menu-tree. How if possible?

I don't understand why you want to handle this with menus.
If you want "to browse the directory structure and to point to the desired
folder", it's done with a Dialog:

  DIM myPath as String
  Dialog.Title = "Look for the mobile phone"
  Dialog.Path = System.Path
  If Dialog.SelectDirectory() Then Return
  myPath = Dialog.Path
  Print myPath

Instead of 'System.Path' you could define any start folder.
And afterwards you can copy things easily to myPath on the phone.

Or do I misunderstand you completely?

Yes, you did:
Let's say I have a TableView with elements (files) which could be copied
onto a USB device. I have a popup menu attached to that TableView, and if
I'd invoke right-click over an element, the program would inspect whether
there are USB devices attached to the PC, and if yes, it would offer to
choose between them (right now it works with max. 2 devices) and it would
build the directory tree of the choosen device and I could point to the
folder 'playlists' for example, and the program would copy the element into
USB's ~/.../playlists folder.
Why? Because it's more elegant way than the dialogs! It already works for
the USB device's root folder but no deeper. Is it clear now?

Off course, I would like to have a menu structure where each submenu item
represents a subfolder recursively.

Subject: [Gambas-user]  gb.image: how to keep a rotated image centered
Message-ID: <29356475.post@...1379...>


I'm attempting to rotate an image about its center point, using something
like:

DIM background AS Image = Image.Load("grass.png")
DIM f AS Float

FOR f = 0 TO 6.2831853 STEP 0.01
  Draw.Begin(DrawingArea)
    Draw.Image(background.Rotate(f), 0, 0)
  Draw.End
  WAIT
NEXT

The resolution of the returned rotated image actually changes based on the
angle, such that the entire original image is preserved (no clipping
occurs). This would be extremely useful in most cases, but not in mine as
I'm making a game.

Anyone know what math I should use to try to keep the rotated image centered
about its mid-point while being rotated? Thanks all.

There is probably more efficient ways, but quick and dirty...
Here:

DIM background AS Image = Image.Load("kuva1.jpg")
DIM bg2 AS Image
DIM f AS Float
DIM ii AS Integer
DIM jj AS Integer

ii = background.Width / 2
jj = background.Height / 2

 FOR f = 0 TO 6.2831853 STEP 0.01
 Draw.Begin(DrawingArea1)
 bg2 = background.Rotate(f)
 Draw.Image(bg2, (ii - (bg2.Width / 2)), (jj - (bg2.Height / 2)))
 Draw.End
 WAIT
 NEXT

Hi Mato,

I have put together a quick demonstration project which parses a String
(out of a TextArea on the Form) of XML and places the result into a
TreeView (on the same Form).

Attached you will find a tar file of the project, plus a screen shot.

The code is based on an article I found at
http://es.wikibooks.org/wiki/Gambas/Manipular_documentos_XML (Thanks and
all credit to the original author!!!)

I made some slight changes as the code didn't quite work in its original
form with the XML as given.

Regards,
Caveat

Subject: [Gambas-user] form.resize works only once with gb.gtk
Message-ID: <4C5DAFBD.7070002@...1907...>

Hi All,

To restrict minimum size of form, I wrote following code.

PUBLIC SUB Form_Resize()
   IF FMain.Height < 300 THEN
      FMain.Height = 300
   ENDIF
END

But this works only once with gb.gtk.
It seems 2nd and later resize method ignored.)

It works fine with gb.qt.

I'm running gambas-2.21.0 with gnome-2.30.2, gtk-2.20, qt-3.3.8.

Possibly a bug in gb.gtk? (of course I'm not sure;)

Thanks,

Hello again Mato

I don't really get this code.  Why do you set xml8tracks to new
XMLReader, then immediately set it to the return from urlDownload?

Where is urlDownload defined?  What does it return?  Where do you define
xml8tracks? What is smix?  Why is smix defined as String [10, 4]?  Is
that something you know upfront?  In the "name" case, your debug could
be confusing as you print that you're showing smix[id, 0] but you
actually show smix[0, 0].

Please send us enough of the code that we can see what's going on and
help a little more...

My first tentative thought is that the odd, seemingly contradictory
message "I wanted an Array but I got an Array" could be complaining
because it's expecting one type of Array but getting another (so looking
for a one-dimensional String Array but getting a 2-D one, or looking
forRegards,classes a String Array but getting a kind of Variant one or
so... ).

But all that aside... I think that you need to start thinking in a more
object-oriented way, so I've started you off with the changes to
TestProject3 (see attached) to make it more oo.  You'll notice I've
added 3 classes, Response, MixUser, and Mix.  The Response class holds a
Collection of Mixes, the Mix class has a MixUser ... look at the
procedure UseClasses on the Form to start to get an idea of how you'd
need to use the classes.

Create a new instance of the Response class when you get your XML, as
you go through the XML and hit a new mix, create a new Mix object, when
you get to a User, create a new MixUser object... when you hit the end
of a Mix object, add that to the Response object... etc. etc. 

Sorry, I really have to go... let me know if you're still stuck!!

Regards,
Caveat

Hi

I can change a gridview with mode = multiple to single  with:
'----------------------------
Public Sub radbutSingle_Click()
  GridView1.mode = 1
End
'----------------------------
and it works but I cannot do it the other way round. i.e. if the mode is
single then:
'----------------------------
Public Sub radbutMultiple_Click()
  GridView1.Mode = 2
End
'----------------------------
has no effect. Is this right?

Mint 9, Gambas 2.19 or Gambas 3(3097), QT

Is it natural to make things more complicated than they need to be or is it
just me?:blush::blush:

I will use a multi-select gridview and treat one with only one selected line
as the special case I need.

thks anyway.

just an economist. It's only a hobby.

But the most important thing to not moving to oop, or not moving
successfully, is that I started programming in basic, some scriping
lenguajes, PHP...and so on. So I'm not too familiarized with oop, and I
couldn't find a good manual about it (I'm sure it exists), adding that
gambas documentation is very poor.

BTW, your code is excelent, and shows in a clear way the benefits of OOP. So
I will take the code as start point, and I'll try to improve my oop with
gambas.

So I will ask many questions on the list...so be patient, please!!!!

Regards,
Mato.-

Subject: [Gambas-user] Me.Close in a multi-form application
Message-ID: <626305.73655.qm@...2469...>

hi,

i have a multiform application, on the Close event of each form a confirmation dialog is displayed. 

The user clicks a button on each form to move to the next one(or clicks a button to go back to the previous form), when he/she does this the current form's Visible property is set to false and that of the desired form is set to true.

When the user exits the application, Me.Close would only close the current form and all previous forms would remain in memory. I remember reading from the documentation that QUIT should not be used in GUI applications. If i close all previously opened forms by using FormName.Close each form's confirmation dialog pops up.

I've been thinking of way out of this, the only idea i've been able to come up with is that if there is a way a function could tell who called it, i could use that to prevent the confirmation dialogs from being displayed on form close. 

Say user closes Form C, now Forms A & B are have their Visible property set to False so they are hidden. On the Close event of Form C i call Form A,B & C's Close method. If Form A & B's Close method could tell that they've been called from another form, then maybe i could prevent the confirmation dialogs from popping up. Or could there be some other way to do this?

I have a attached a sample application which illustrates the problem.

Thanks in advance :)

Hi Vikram,

There are probably much better ways to do what you are trying to do, but its 
hard to suggest them fro the sample.

But for a quick answer:
PUBLIC SUB Form_Close()
  DIM retval AS Integer
  
  IF NOT ME.Visible THEN 
    ME.Close
    RETURN 
  ENDIF 
  
  retval = Message.Question("Are you sure you want to exit FormA?", "Yes", 
"No")
  
  IF retval = 1
    ME.Close
  ELSE 
    STOP EVENT 
  END IF
  
END

Hi,

the help system now is much better then in Gambas2.
But one thing: the Type property of the help browser is set to "Utility". This

This is annoying!

Great minds must think alike. I didn't receive a notification email about
your post for some reason, but independently developed the same code almost
exactly. Crazy, huh? Your code (and my code) do the trick nicely. Here's
mine: http://old.nabble.com/file/p29413377/gb.image_rotate.tar.bz2
gb.image_rotate.tar.bz2

  DrawingArea.Width = Desktop.Width

  ' Rotate the background and update the drawing area.
  FMain.Show
  t = Timer
  FOR f = 0 TO 6.2831853 * 1 STEP 0.01
    bg_rotated = bg_normal.Rotate(f)
    bg_cropped = bg_rotated.Copy((bg_rotated.Width - 1024) / 2,
(bg_rotated.Height - 1024) / 2, 1024, 1024)
    Draw.Begin(DrawingArea)
      Draw.Image(bg_cropped, 0, 0)
    Draw.End
    frames = frames + 1
    WAIT
  NEXT

  ' Display frames per second rendered.
  PRINT frames / (Timer - t) & " frames per second"

  ' End the program.

Subject: [Gambas-user]  gb.image: image alpha channel accessibility
Message-ID: <29413575.post@...1379...>


I'm writing a game and am exploring my graphical options using gb.image.
While it's not hardware accelerated, it's easier to get into than OpenGL and
the SDL component seems to be missing key features such as image rotation.
The various filter/effect methods also offer a huge range of possibilities,
CPU speed permitting.

The GAMBAS documentation states that images in gb.image are treated as
read/write arrays, which I'm assuming means that they're allocated in memory
similarly and that their elements are accessed similarly. .Load, .Copy and
.Draw operate on the alpha channel and RGB channel together, but I don't see
any way to read or write to an image's alpha channel exclusively. Is this
possible, and if so, how?

If the only available method is something like getting the pointer to where
the image is stored in memory and accessing it one pixel at a time, it might
be a good idea to expand the existing gb.image methods to include performing
operations specifically on the alpha channel. This could also be
accomplished by allowing all the existing methods to work directly on the
alpha channel, such as .Copy and .Draw.

As always, any ideas or reflections are appreciated.

- There is no rotation in gb.image because I don't have the algorithm at the 
moment. It is a bit complex, because all gb.image color formats should be 
supported.

- The alpha channel is the highest byte of the 4-bytes pixel color. What do 
you want to do with the alpha channel?

Did you mean the SDL component? gb.image does have rotation (although I
don't know if it preserves the alpha channel):

Thanks, that is good to know. Briefly, I'd like to copy the alpha channel
from one image to the alpha channel of another image, preserving the target
RGB channel. It would be like using Image.Draw but being able to specify the
source channel[s] (RGB, Alpha, All) and destination channel[s] (RGB, Alpha,
All).

Specifically, the game I'm writing uses a layered landscape (bedrock, sand,
soil, vegetation, snow) with one large tileable texture for each layer. As
each layer is rendered it needs to be seamlessly blended with the other
layers using smaller alpha channel images. The smaller images used only for
their alpha channel are "interconnective" or "in-between" tiles and create a
smooth transition between, for example, sand and grass tiles.

I could address the pixels individually, but that would be super inefficient
as opposed to using a GAMBAS method with its underlying C code's speed. I'm
probably pushing GAMBAS in a direction it wasn't meant to go, but
nevertheless that would be a damn useful functionality for games and
graphics apps.

Let me know what you think, and here's my web site if you're curious:

It took me a while to hand make this in GIMP, but here's the idea:

http://www.eightvirtues.com/misc/alpha_stuff.xcf

There are eight tiles that use only alpha (ten if you include fully opaque
and fully transparent), which are applied to a larger texture to make parts
of it transparent to expose the underlying layers. In the GIMP file the
eight tiles' alpha channels have been applied to the grass layer,
effectively removing the undesired parts of it to expose the sand layer.

Basically, copying only the alpha channel of an image to the alpha channel
of another image opens up all kinds of graphical possibilities. The alpha
channel is one of the few things that can make 2D graphics look great,
whether used normally or creatively.

I have configured the KDE window manager to roll/unroll windows when using the 
mouse wheel on the window title bar. 

That way, I can hide the search window and unhide it easily.

But I understand your problem, and maybe I can add an option for that...

I made an Image.DrawAlpha() method for you in revision #3101. Tell me if this 
is was you need.

Just a warning for Mandriva users...

If you install KDE 4.5 packages on Mandriva 2010.1, then you won't be able to 
compile the Qt4 component, because a file in the qt4-devel package has a bug.

The bad file is named "libQtWebKit.la" and is located in /usr/lib (or 
/usr/lib64 on 64 bits systems).

I join a fixed libQtWebKit.la so that everything compiles correctly!

Am compiling now and will run test code using the new method to produce
tiling with different layers. Thank you so much. I'll post my code when I
get a proof-of-concept sample working. Awesome! =)

The Orientation property takes one of the following values:

	PdfDocument.Normal
	PdfDocument.Sideways
	PdfDocument.Inverted
	PdfDocument.SidewaysInverted

The only way I see is testing the dimensions of the page.

Hi!
If form is invoked with ShowModal in certain situation it prevents
form to close --> hang.

Hi all.

I will have to distribute a little programm, so I will have to install
Gambas 2.x too, I asume. My question is: Will there be any conflicts
between the SVN for Gambas 3.x rev. 3098 and a new installation of 2.x?
I will mainly dewvelop with the SVN, so I'd rather seek another solution
than to mess up a working environment.

Thanks and regards,
Dag-Jarle Johansen

Gambas 2 and Gambas 3 are installed in their own directory, and the files 
installed in common directories (like /usr/bin or /usr/local/bin) are named 
differently.

So you can have them both on your machine. How could I do otherwise? :-)

There seems to be workaround for this bug.
Instead of this:

Public Form1 As New FForm1
Public Form2 As New FForm2

Public Sub Main()

  If Form1.ShowModal() = 666 Then
  Form2.ShowModal()
  Endif

End


This works:

Public Form1 As New FForm1
Public Form2 As FForm2

Public Sub Main()

  If Form1.ShowModal() = 666 Then
  Form2 = New FForm2
  Form2.ShowModal()
  Endif

End

At least this workaround works with revision 3117.

Gambas decides that the first shown window is the "main" window, and that 
closing it closes all other ones.

So when Form1.ShowModal() returns, Form2 has been destroyed, and you get an 
"invalid" object.

Yes, after I wrote my mail, I figured it may be the case.
Problem is that my program is oriented to module.
It invokes forms when needed and shows with them what
happens inside of module.

Project I'm working on is big, old and messy. It is ported from vb6.
Now I'm trying to make code more clear, but I'm getting signal 11.
I can't send this project to you, but I'm trying to isolate the problem.
Do gdb outputs help you without source code?
However, here:

Program received signal SIGSEGV, Segmentation fault.
my_free (alloc=0x1e1d150a1e1d150a) at ../share/gb_alloc_temp.h:333
333		pool = (size / SIZE_INC) - 1;

Yes. Maybe that automatic main window feature should be optional...

Yes, but not necessarily. If a bug corrupts memory, then the crash can occurs 
later, and then the backtrace is meaningless.

The better is using valgrind and reproducing the crash. To do that, run your 
project that way:

$ cd /path/to/my/project
$ valgrind --tool=memcheck --num-callers=50 --track-origins=yes gbx3
...

Do what is needed to get a crash, and then send me the valgrind output.

Sometimes, the program won't crash, because valgrind always tries to continue 
even after a segmentation fault. Send me the valgrind output anyway!

Subject: [Gambas-user] SHELL is more faster than SUB Process_Read()
Message-ID: <AANLkTimjHoncF1mKPwXSV=LfyXprAgUk7UQGmM4RFB59@...627...>

Hi i wrote a test program that "ls -1" a directory with 1700 and more files
(mp3).

i wanted to make a string as following

  Content = "/mnt/store/MUSIC/free/new age/webradio recs/Trancemission.FM
Radio 128K- New Age 2- new experience of meditation and new age music -
livestream 128k/" & sLine

in order to list with full path the files.

but i dont get the wanted result.


The SHELL command runs faster than Process_Read.

This mess up the result of concatenation.

The code is the following:

--------------------------------------------------------------------------------
' Gambas class file

PUBLIC SUB Button1_Click()
  SHELL "ls -1 \'/mnt/store/MUSIC/free/new age/webradio
recs/Trancemission.FM Radio 128K- New Age 2- new experience of meditation
and new age music - livestream 128k/\'" FOR READ

END

PUBLIC SUB Process_Read()

  DIM sLine AS String
  DIM Content AS String

'  IF Eof(LAST) THEN RETURN

  READ #LAST, sLine

  Content = "/mnt/store/MUSIC/free/new age/webradio recs/Trancemission.FM
Radio 128K- New Age 2- new experience of meditation and new age music -
livestream 128k/" & sLine
  PRINT Content;


CATCH
Message("Error code " & Error.Code & " Error message " & Error.Text)

END

--------------------------------------------------------------------------------

Also i get EOF but the PRINT still runs in background.

Is this behavior normal?

Did you try the revision #3116 or are you using something older ?

yes in the ide ... try this program in a console without the ide ...
for that generate an executable...

that's because the ide and qt make a buffer of not already showed
entries and the editor that is used to show the entry is a bit slower

Subject: [Gambas-user] EXEC or SHELL can not READ WRITE simultaneously well
	with process?
Message-ID: <AANLkTinyy13dxgAojUAp85wE4p1wMrnQ1_PO8mpc8KgJ@...627...>

I have searched around with Google but still can not find an other problem
like mine.
My code below base on the Console example project of Gambas.
I want run a process like this:

PUBLIC $mainProcess AS Process

PUBLIC SUB Form_Open()

    $mainProcess = SHELL "7z x /demo/file.7z -o/tmp" FOR READ WRITE '
Extract /demo/file.7z to /tmp folder, same problem with EXEC

END

Note that I have extracted this file to /tmp before, so 7z will ask
overwrite or not. And I want take control and answer from Gambas:

PUBLIC SUB Process_Read()

DIM sLine AS String

  LINE INPUT #$mainProcess, sLine ' I used READ #$mainProcess, sLine, -256
too, but it break some line, and read multiple line in same moment
  txtLog.Text &= sLine & gb.newline
  IF InStr(sLine, "(Y)es / (N)o / (A)lways / (S)kip all / A(u)to rename all
/ (Q)uit?") > 0 THEN
      ' A message.question here, then print an answer like this
      PRINT #$mainProcess, "Q" ' Quit the process
  ENDIF

END

Also I created a button to manually response to process:

PRIVATE SUB Button1_Click()

   PRINT #$mainProcess, "Q"

END

Finally, to detect program working:

PUBLIC SUB Process_Kill()

     Message.Info("Process terminated")

END

My problem is, if I use FOR READ WRITE, I can't get the process output until
process terminates (SUB Process_Read() seems not work - txtLog is blank).
When I click the Button1, the process terminates immediately, and now the
output appears in txtLog text box.
If I use FOR INPUT OUTPUT, I can get the output like I want - the output
appears in txtLog text box, (SUB Process_Read() work => PRINT "Quit" message
to process) but process not terminates, even when I click Button1.

An other small problem is from Gambas IDE. I use shortcut keys (Ctrl+C,
Ctrl+X) to copy, cut text from Gambas Editor (when cut, the selected text
disappears), but I can not paste anywhere, even back to Gambas editor. But I
use the context menu, it works fine.

My Gambas version is 2.20 (full is 2.20.2-1.fc13.i686) on Fedora 13. My
machiine is DELL Inspiron 1440 (Pen Dual Core).
Thank for answers. Sorry for my English.

You must not use 'LINE INPUT #Process, Var' to read a process output in 
Process_Read. You must use 'READ #Process, Var, -MaxLength', add 'Var' to a 
'Buffer', and extract lines from that 'Buffer'.

Without a full project to test, I cannot say more at the moment.

Note that Gambas 3 is more clever than Gambas 2 for that kind of situation.

CTRL+V works perfectly there. Do you have more details?

That line is not correct, because you are reading the string from the stream 
in the internal Gambas format (length stored in one, two or four bytes, 
followed by the string contents), whereas the process just send characters on 
its standard output. See the documentation on READ for more details.

You must do that to read the standard output of a process:

PRIVATE $sBuffer AS String

PUBLIC SUB Process_Read()

  READ #LAST, sData, Lof(#LAST)
  $sBuffer &= sData

  DO
    iPos = Instr($sBuffer, "\n")
    IF iPos = 0 THEN BREAK
    sLine = Left($sBuffer, iPos - 1)
    $sBuffer = Mid$($sBuffer, iPos + 1)

    ' Do what you need with sLine

  LOOP

END

Subject: [Gambas-user] Pretty printer
Message-ID: <201008161638.12672.gambas@...1...>

Hi,

Just before leaving Paris (and my computer) for a week, I have added a pretty 
printer in the IDE code editor.

Run it by clicking on the magic wand button in the toolbar.

It is a bit rudimentary, but I think it will make all the randomly indented 
code I often receive more readable for me. :-)

And if you have suggestions about what kind of options that pretty printer may 
have, tell me. That way, I will be able to make it automatic.

Regards,

1. Thank you for your response, it works better now.

2.The  problem of shortcuts keys Ctrl+C, Ctrl+X is: when I use those
shortcut keys, I can paste only to the Gambas project editor window from
where I copy (I can paste to different tabs). When I switch to other windows
e.g gedit or an other Gambas project window, there's nothing to paste. But
when return to the first Gambas project window, I still can paste. It's like
that the shortcut keys use a "local clipboard" not the clipboard of system.
But this problem doesn't happen with the context menu. (Paste here include
both Ctrl+V and menu).

Hi!
TrayIcon seems to work perfectly,
until program that uses it, is started at startup of OS.
Program is started with following command;
gbr2 /home/MyName/ProgramsName.gambas


Program has following code:

PUBLIC Kuvake AS NEW TrayIcon AS "TrayIkoni"

PUBLIC SUB Form_Open()

  Kuvake.Picture = Picture.Load("ikoni.png")
  Kuvake.Show()

....


Following problems:
With GTK+, trayicon never appears, everything else works fine.
With Qt, error message at startup:
"

Subject: [Gambas-user] error when using a custom control
Message-ID: <AANLkTimLpe+cfbjram7RWJbfe_yobEkmudSf4Jc6ge=i@...627...>

Hi everybody.

I wrote a custom control using Gambas 2.21, is not finished yet but I
need test packaging and installation.

I installed it on two virtualized tests machines (ubuntu and kubuntu
10.04 by virtualbox). I installed Gambas 2.18 too, from repositories.

When I add the control to a test proyect, the below error message is displayed:

"UserControl class is missing in 'yourclass' component exported classes"

"yourclass" is the name of my custom control.

I understand that if a custom class inherits from another custom
class, both must be exported. But how I could to export "UserControl"?

Salut,

tell me if I'm wrong. I understand you like this.

You made a gambas2.component and when you use it the first time you get
that message. Right ?

For gambas2.components I know that they after compiling chosen in there
own project components list.

You can see it while loading the project into the IDE on a box where it
hadn't be used before.The component is claimed missing.

Just press continue.

Thanks, Fabien. I forgot configure the tab "Requires" in the
properties dialog. (But the error message led me in the wrong way).

I couldn't find it in GAMBAS 2 so I built GAMBAS 3. It had the new method,
however I was unable to test it because Image.Draw() seemed not to work.
Here's the project, so please let me know if something changed in GAMBAS 3
that caused this code to no longer work:

http://old.nabble.com/file/p29476167/gb.image_drawalpha.tar.bz2
gb.image_drawalpha.tar.bz2 

Also, does GAMBAS 3 have different dev dependencies than GAMBAS 2 for
compiling? I successfully compile GAMBAS 2 all the time, but this was my
first time compiling GAMBAS 3.

this is not a bug but a feature... when a part of a line is selected
the tab is added in the beginning of the line, and shift+tab remove it
(2 spaces in fact)

this feature is to help in code indentation

As I know, there's no way to do that.
The only way to develop app for Iphone ( and this app can run on device /
sell on store ) is use xcode IDE running on Mac.

According to Apple's own iPhone developer agreement,

"Applications must be originally written in Objective-C, C, C++, or 
JavaScript as executed by the iPhone OS WebKit engine, and only code 
written in C, C++, and Objective-C may compile and directly link against 
the Documented APIs ..."

So even if you were able to write programs for the iPhone in Gambas, doing 
so would get you rejected from the App Store.  To develop more than web 
apps for the iPhone, you need to buy a Mac and learn Objective-C (which is 
their preferred language), C or C++.  Most likely Objective-C, since C and 
C++ can be used in cross-platform toolkits and Apple is doing its best to 
kill those off.  They might institute an Objective-C-only policy in the 
future.

It may be possible to port Gambas and an X server to the iPhone/iPad for 
use by users with jailbroken devices, but without a profit or fame motive, 
I don't see anyone putting the effort into that.

I already went down this path about a year ago, and Apple's only gotten 
stricter since then.

Message-ID: <1282270285.3900.0.camel@...2461...>

Hello, I'm half a cumbersome problem, I try to run a shell to my mplayer
variable declared as a process.

What is the running mplayer python interactive console which I call a
player, my problem is:

Once called the SHELL ("python"), you run the console, but not how to
enter new commands to the console.

I tried to run SHELL ("import pygame") to write it in the terminal, but
does not.

Does anyone could tell me I'm doing wrong, or perhaps some example code?

Write a python program as a separate file (.py extension) and get it working
to do what you want.

Then run it from Gambas:

 Exec ["/usr/bin/python","/path/to/my/script.py"]

I just verified that the build dependencies were satisfied and recompiled
GAMBAS 3:

sudo apt-get install build-essential libffi-dev libbz2-dev libfbclient2
firebird2.1-dev libmysqlclient15-dev unixodbc-dev libpq-dev libsqlite0-dev
libsqlite3-dev libxtst-dev libgtk2.0-dev libgtkglext1-dev librsvg2-dev

libqt3-mt-dev kdelibs4-dev libsdl-image1.2-dev libsdl-sound1.2-dev
libsdl-mixer1.2-dev libxml2-dev libxslt1-dev

sudo rm -fr trunk
mkdir trunk
svn checkout https://gambas.svn.sourceforge.net/svnroot/gambas/gambas/trunk/
cd trunk
./reconf-all
./configure
make
sudo make install
gambas3

The results were the same (program runs but PictureBox control remains
black), so I tried creating a fresh GAMBAS 3 project:

http://old.nabble.com/file/p29496338/gb.image_drawalpha.tar.bz2
gb.image_drawalpha.tar.bz2 

It still won't display an image. I'd like to copy/paste the code for
Image.DrawAlpha from the GAMBAS 3 checkout to the GAMBAS 2 checkout and see
if it works under a more stable GAMBAS. Is there anything I should look for
other than the obvious (to a non-C programmer) to make that work?

What about android on arm? Gambas can compile in arm right?
There's a lot of cheap (made in china) android tablet in the market.
If gambas (ide and compiled app.) can run on those platform, I'd like to 
order some of those.
Would be nice too, since we would be able to make android application 
using gambas, even develop on it too.

Android is Linux-based but doesn't run X.  You code for it in Java using 
Google's own APIs.  But they recently came out with a "native development 
kit" to allow easier porting of games, and it might be that parts of Gambas 
could be ported to that.  

Someone has started working on porting Qt to Android, also using the NDK.  
Until that's ready, you'd have to either roll your own interfaces in SDL or 
write your own widget set for Android, though (I think a gb.sdl.interface 
component has been a long time coming but haven't had time myself.)  Either 
way, you'll be running into the problem that your apps don't look native, 
so you might as well just be writing a web app.  But it should be possible.  

I've been writing Java code on and off for about 12 years, so I've been 
doing some Android development myself, using Eclipse and some plugins to 
make GUI development less of a pain.  But it's not as elegant as Gambas, 
and likely never will be.  

Google also has "App Inventor", which allows you to make basic Android apps 
with little to no coding, but at a much higher level than Gambas, with far 
less control (they provide pre-coded graphical "blocks" to assemble your 
program logic, flowchart style, instead of controls and methods/properties 
like Gambas).  It's more like one of the old game construction kits from 
the 90s than a development environment, but all they're doing is changing 
commands and parameters to little puzzle pieces you fit together into 
"blocks" that are essentially lines of code.  

You have to request an invitation, so I haven't tried it yet.  I also don't 
think you can start an app in there and finish it by writing code in 
Eclipse.  But I guess that's what I'd recommend trying for a Gambas 
programmer who wants to develop for Android, at least until someone ports 
Gambas in a way that makes it feel native.

I've been waiting for a cheap Chinese tablet with a multitouch capacitative 
touchscreen as a test device, since most phones coming out now are 
multitouch and capacitative (use your finger, not a stylus).  If you know 
of any like that and could send me a link privately, I'd appreciate it.

Can anyone help me to fit a jpeg photo into a picturebox?

PictureBox1.Picture = Picture.Load("dir/pic1.jpeg") shows only a small part
of the photo.

Thanks

Thanks Charlie - works fine.  I did try it earlier and my system hung-up so I
presumed I'd done something stupid.

Thanks again

I found the relevant bits of code, but it looks like the code is quite a bit
different between GAMBAS 2 and 3, so without knowing C I wasn't able to get
the new code to compile properly. I guess I'll continue to wait until GAMBAS
3 has reached a stable enough point that I'm able to test the new function.

hi,
I extracted the form from my project and put in a blank project. If I
do any modification and try to save, I get this error :
Cannot save file ! Null object (CControl.GetEachProperty.1226)
It happen with gambas2-2.21.0_3124 and the project can be run without
any error :-)

Subject: [Gambas-user] Converting strings to numbers with localization issues
Message-ID: <4C724391.2090605@...1740...>

  In my project I have several temp values in the form of 31.72 C

They are stored as string and I convert them with Val(sValue)

My project is translatable, default language is en_US.UTF-8

If I change System.Language, Val doesn't know how to convert the value 
correctly (or it does it correctly, but I have to change my code)

Anyone had this problem and knows how to prevent the system from leaving 
out point or comma's or the complete value?

Example project with output:

' Gambas module file

PUBLIC SUB Main()

   DIM sValue AS String = "31,72"

   PRINT "Original Value -> " & sValue

   PRINT System.Language & " -> ";
   PRINT Val(sValue)

   System.Language = "nl_NL.UTF-8"
   PRINT System.Language & " -> ";
   PRINT Val(sValue)

   System.Language = "de_DE.UTF-8"
   PRINT System.Language & " -> ";
   PRINT Val(sValue)

   sValue = "31.72"
   PRINT "\nOriginal Value -> " & sValue

   PRINT System.Language & " -> ";
   PRINT Val(sValue)

   System.Language = "nl_NL.UTF-8"
   PRINT System.Language & " -> ";
   PRINT Val(sValue)

   System.Language = "de_DE.UTF-8"
   PRINT System.Language & " -> ";
   PRINT Val(sValue)

END

OUTPUT IS:

Original Value -> 31,72
en_US.UTF-8 -> 3172
nl_NL.UTF-8 -> 31,72
de_DE.UTF-8 -> 31,72

Original Value -> 31.72
de_DE.UTF-8 -> 3172
nl_NL.UTF-8 ->
de_DE.UTF-8 -> 3172

So if I store it with . or , it's false interpreted by at least one of 
the languages...
I do not have the same values, I also store energy usage and other 
values in the form of 41.322 Watts, so the decimal point is not always at 2

I remember this type of discussion regarding currency, how was it solved?

Please any input is welcome.

Ron_2nd.

The meaning of "." and "," in numbers changes with the language (the 
"localization"), and Val() follows the localization settings, so all that is 
logical.

So use CFloat() instead of Val() to have a behaviour that does not depends on 
localization, and create your own conversion function with it.

I have noticed that when using CFloat(sValue)  I have to check/translate 
commas to dots first if found in string, otherwise CFloat says 'wanted 
float got string instead'

Would be handy to know what Val() does behind the scene, do you know 
without having to search through your code? It's hard for me to find.

What Val() does is explained in its wiki documentation page. What information 
do you need that is not in that page?

I was thinking about the code behind it, but it's not important.

One last question, is the behaviour below normal?
The first CFloat (en_US) returns a dot while the rest returns a comma in 
the result, ie the are not consistant either, I must have overlooked 
something..or .?

PUBLIC SUB Main()

   DIM sValue AS String = "31,72"

   ' replace , by .
   sValue = Replace(sValue, ",", ".", gb.String)

   PRINT "Original Value -> " & sValue

   PRINT System.Language & " -> ";
   PRINT CFloat(sValue)

   System.Language = "nl_NL.UTF-8"
   PRINT System.Language & " -> ";
   PRINT CFloat(sValue)

   System.Language = "de_DE.UTF-8"
   PRINT System.Language & " -> ";
   PRINT CFloat(sValue)

END

OUTPUTS:

Original Value -> 31.72
en_US.UTF-8 -> 31.72
nl_NL.UTF-8 -> 31,72
de_DE.UTF-8 -> 31,72

Ron_2nd.

CFLoat return a Float variable ... so PRINT just see a variable and
not a convertion funtion ... PRINT do what it do for every float,
display the number in localization settings.

  Fabien,

you are right, of course... they will be translated by Str$

I changed PRINT to WRITE just to test,  and the pattern is the same for 
all 4.

Finally a way to get this fixed, now I have to check my massive project 
for my wrongly used Val()'s

Thanks both Beno?t and Fabien.

Ron_2nd.

I tested with stable 2.21 and was ok but not with 2.21_3124 very strange.
will try to rebuild Gambas2 from SVN.

I tested your project, and it works when the form has Border = True. But the 
DrawingArea contents is not visible when Border = False. Strange bug, 
apparently related to the Border property, not to the drawing routines.

The TrayIcon must be embedded in a System tray to work. The system tray is 
(usually) managed by the desktop panel, so maybe your desktop panel is not yet 
visible when your program is run?

Strange: it works perfectly as expected there. I copy some text with CTRL+C, 
and I paste it in gedit with CTRL+V, and that works!

Yes, I modified startup, now there is 10s delay before starting gbr2.
And everything works.
Maybe I should write function to check if desktop panel is started or not.

BTW. Does anyone know why sleep 10 && gbr2 ... doesn't work?
It works in terminal, but in System --> Preferences --> Startup
Applications, it doesn't.
I had to do this via script to make it work.
Is this some linux restriction or bug in Ubuntu?

Hi,

I finally wrote the tutorial about using external declarations.

It is a long text and perhaps difficult, but I didn't find any other way 
to put it in a simpler form: the problem of interfacing gambas to 
external libraries, from the perspective of a gambas user, is not simple.

I wrote it using zim, a nice wiki editor. I attach what I exported from 
the document, in both html and "Txt2Tags" (?) format.

Feel free to modify it as needed, to include it in the wiki, or 
whatever. I attach two projects related to the explanation, one short 
and simple and one much more complex, but more funny.

This document regards Gambas2. When it will be corrected/approved, I 
will port projects and documentation to Gambas3.

Now some technical question.

In the Drum Machine project, after having verified that it works 
correctly using pointers for read/write, I tried to create a new class 
which should be a gambas representation for an alsa event (which is a C 
struct). It does not work, and I don't know how to debug it (well, I 
could, using gdb or similar, but I was looking for a more direct way). 
My idea was to point a pointer to the instance of the class CEvent, and 
then dump a few bytes to see them. But gambas does not let me to assign 
a pointer to a class instance ("wanted integer, found object").

Moreover, in the gambas 3 documentation there is nothing that makes me 
think that "write #pointer, ..." is no more supported. Either gambas3 
supports it (but it does not seems to me), or the documentation is wrong.

Another thing is that if I declare a constant as a byte, and then try to 
"write #pointer, my_byte_constant", 4 bytes are written instead of just 
one. I had to mention it in the document.

I am really curious to give a try to gambas3 structures, but I want 
firstly terminate with gambas2.

Best regards,
Doriano Blengino

   How to interface Gambas to external libraries

INTRODUCTION

   There are lots of shared libraries available in a Linux system, capable of
   doing a lot of useful things, and many of those libraries can be used from
   Gambas using some of its features.

   The  first step to do is to find a suitable library to use for a given
   purpose; not all the libraries can be used, but the vast majority can. The
   prerequisite is that the library is written in plain C. Most libraries are
   written in C, while others are written in C++ and, perhaps, still other
   languages. This document will focus only about C libraries.

   Once the intended library is found, its general logic must be understood in
   order to determine what is needed, and how this new stuff will be used by
   the final program. The full documentation of the library, and possibly some
   example, should be readed carefully. Libraries are not programs, and hence
   their philosophy is quite different. A program tends to contain only the
   subroutines  required  to do its job, while a library is what the name
   implies:  a  collection of subroutines, to be used many times, by many
   different programs. It is not uncommon to find, inside libraries, two or
   more subroutines which do the same thing, in a slightly different way.
   Libraries sometimes are written keeping in mind that they will be used by
   different languages, not only C: python, ruby, ocaml, many others, Gambas
   included. Libraries tend to encapsulate the details of a task inside a
   "handle",  in  a  way similar to a Gambas object; but, they don't have
   properties and methods - everything is carried out by calling functions
   which these handles are passed to. If you think at a Gambas class with three
   properties and four methods, an external library implementing the same thing
   will have at least seven (three+four) subroutines, and probably a couple
   more to create and destroy the object. Other than this, there is not a big
   difference from setting a property and calling a function, the latter is
   simply  a  bit longer to write. To search for what we need, we must be
   prepared to read a lot of documentation, too often badly written (hey,
   apropos, how well do we document our software?).

THE EXTERN DECLARATION

   Extern  declaration  is  simple. It is like a normal Gambas subroutine
   declaration, but preceded by "EXTERN". The EXTERN keyword says to gambas
   that the body of the procedure is not defined by the gambas program we are
   writing, but somewhere else (an external library). We must also specify
   which  library  to  use:  this  is done by the clause "IN libraryXXX".
   Alternatively, you can use a separate LIBRARY statement: all the subsequent
   extern declarations will refer to this statement. Either "IN library" or
   "LIBRARY  xxx" can specify a version number after a colon, and this is
   recommended.

   Let's see an example, choosen because of its simplicity:
LIBRARY "libc:6"
EXTERN getgid() AS Integer

   These two lines say that a function named "getgid" exists in the library
   "libc" version 6. This function takes no parameters, and returns an integer
   (the group ID).

   The same thing can be written like this:
EXTERN getgid() AS Integer IN "libc:6"

   Another example, slightly more complicated. This time we have parameters,
   and the last thing to say about the formal declaration:
' int kill(pid_t pid, int sig);
EXTERN killme(pid AS Integer, sig AS Integer) AS Integer IN "libc:6" EXEC "kill
"

   The first line (the comment) shows the original declaration, and the second
   line the gambas one. We can note a number of things. First, what does the
   original declaration mean? It means "a function called kill returns an int,
   and it accepts two parameters. The first is named pid and its type is pid_t;
   the second is named sig and its type is int". Contrary to Gambas, the C
   language puts the type of a variable before the variable instead of after.
   Second, what in Gambas is called "Integer", in C is called "int". Third,
   what is "pid_t"? It's a type; we can understand it because it is written in
   a place where a type specifier is expected, and because ends with "_t"
   (underscore t).
   Third, a new clause EXEC "kill" is used in the Gambas declaration. This is
   necessary because we want to use a function named kill, but KILL is a name
   already  used  by  Gambas.  So,  in  Gambas, we must name the function
   differently, but anyway we must indicate its true name inside the library.
   The declaration says "I declare an external function named killme, but its
   real name is kill". I chose the name killme because in the attached gambas
   example this function is used to kill the running program.

   To be sincere I noticed that, even without renaming the function from kill
   to killme, the program was working the same. May be that this has something
   to do with case sensitivity - C is sensitive, and Gambas not, so there is
   still a difference between kill (lowercase) and KILL (uppercase). Anyway,
   when there is a possible name conflict, it is best to use this renaming
   technique.

WARNING --- END OF THE EASY PART

   (just joking)

   At this point, several things must be noted. Most of the suitable libraries
   are written in C, which is a different language than Gambas. We will need to
   know at least a little of C declarations, in order to translate them to
   gambas. Referring to the last example, one could ask why I translated the
   pid_t type to integer. The simple and correct answer is "because on my
   system  the  pid_t type is actually an integer". This answer is really
   correct, but must be explained better, talking about agrumes (?). We can
   think  about  lemons and oranges, which both are agrumes, and are very
   similar: they weight more or less the same, and often can be interchanged;
   you can eat them directly, or squeeze them to drink their juice, but it is
   unlikely that you will put orange juice on your fried fish. In C, this is
   expressed by the fact that it is unlikely that you want to use the kill()
   function passing it an arbitrary integer. Surely, you will pass a process
   identifier (PID), which actually is an integer, but it is indicated more
   precisely as pid_t. In my motivation, I also said "on my system the pid_t
   type...". Yes, on my system - on most system, the type pid_t is an integer,
   but this could be different.

   The final answer can be found by typing these two commands in a terminal:
grep -r pid_t /usr/include/* |grep "#define"
grep -r pid_t /usr/include/* |grep typedef

   which will show the involuted way types are managed in C. This argument is
   way too complicated to go further; giving that Gambas runs on Linux, and
   presumably on desktop systems, we can consider that all the parameters
   passed  to  a function, and returned by it, will be either integer, or
   pointers - which are integer too, or strings - which are pointers that are
   integers. There can be also floating point numbers - float and double. The
   following  table  lists  some  of  the  types you can encounter in a C
   declaration, and the suitable type to be used in gambas:
C type                  Gambas type
int                     ->      integer
long                    ->      long
float           ->      single
double          ->      float
xxxx*           ->      pointer (the asterisk means exactly "pointer")
char*           ->      pointer - but see later
other types     ->      integer or pointer (depends on the declaration); see la
ter

   We  will start to briefly introduce pointers, which are little used in
   Gambas. A pointer is an integer, but used very differently. The thing that
   more closely resembles a pointer in Gambas is a class instance. When you
   create, say, a Form in Gambas, a lot of data is stored somewhere in memory.
   That memory will hold all the specific settings of the form: its caption,
   its color, the list of all its children, and so on. The address of that
   block of memory is returned to your program, and stored into the variable
   which refers to the just created form:
MainForm = NEW Form()

   That variable MainForm is really a pointer: in only 4 (or 8) bytes it tracks
   a lot of data, stored somewhere in memory at a specific location (address).
   The  memory  is a long sequence of cells (bytes), each identified by a
   progressive number. A pointer contains the identifying number of a cell of
   memory (its address). In C, pointers are used for two reasons: the first is
   that  passing only an address (a pointer contains an address), is much
   quicker than passing a lot of data; this is the same reason why Gambas
   instance variables like MainForm are similar to pointers.

   The second reason is when the called function should modify the variable we
   pass. For example, if we in Gambas wrote:
INPUT a ' where a is an integer

   in C we would write:
void input(int *a);
...
input(&a);

   The reason is that we want our INPUT command to fill our variable "a". In C,
   we must call input() and say to it where our variable is, in order to let it
   fill the variable. The ampersand "&" takes the address of the variable, and
   passes it to the function. The declaration of input() says "int *a", which
   states that "a" is not an integer, but a pointer to an integer, ie, the
   parameter says where to find the value, not the value itself.

GAMBAS IMPLEMENTATION OF POINTERS

   Gambas has the datatype Pointer, and a set of operations suitable for it. To
   use a pointer, a normal declaration is required like any other variable.
   Then, a value must be assigned to it. When using a normal variable, often
   you can assign a literal, for example you can write "a=3". With pointers,
   this  is not advisable. A pointer gives access to any cell location in
   memory, but you should know in advance what location you are interested in,
   and  that  location  must be the correct one for the intended purpose,
   otherwise Gambas or the operating system will get angry. This is much the
   same  as  saying  that you can not write "MainForm = 3". You can write
   "MainForm = NEW Form()", or "MainForm = AnotherExistentForm", or "MainForm =
   NULL". So, a direct assignment to a pointer will always be to NULL, to
   another pointer, or to a call to some function returning a pointer. Just as
   a class instance variable like MainForm.

   Sometimes an external function returns a pointer, and this pointer will be
   required in order to invoke subsequent calls to the external library. This
   case is much like creating a Form, and using its reference to operate on the
   form itself. In this case, the data behind (pointed by) the pointer is said
   to be "opaque": we can not see through something opaque, so we don't know,
   and we don't want to know. This is the simplest case; an example about this
   is the LDAP library. The first thing to do to interact with LDAP is to open
   a connection to a server. All the subsequent operations will be made on the
   connection created by a specific call. Things go like this:
LIBRARY "libldap:2"
PRIVATE EXTERN ldap_init(host AS String, port AS Integer) AS Pointer
PRIVATE ldapconn as Pointer
...
ldapconn = ldap_init(host, 389)
IF ldapconn = NULL THEN error.Raise("Can not connect to the ldap server")

   As  already  seen, a LIBRARY is specified. Then, an EXTERN function is
   declared; this function is the one which must be called in order to do
   anything with ldap. The last two lines are the ones that, when executed,
   will  open  the connection and store its handle, or instance, for this
   connection. In this specific case, ldap_init() returns NULL if something
   goes wrong, so we can test for NULL to raise an error. Once obtained a
   handle to the connection, this handle must be specified on every subsequent
   call to the ldap library. For example, to delete an entry in the database,
   the following must be used:
PRIVATE EXTERN ldap_delete_s(ldconn AS Pointer, dn AS String) AS Integer
...
PUBLIC SUB remove(dn AS String) AS Integer
DIM res AS Integer
res = ldap_delete_s(ldapconn, dn)

   Unfortunately, things are not always so simple. One of the reasons C uses a
   pointer, is to let the subroutine write some data in the location indicated
   by the calling parameters. Remaining in the initialization of a library,
   ALSA for example is different. To initiate a dialog with the alsa sequencer,
   a handle for the sequencer is needed. The C declaration for this function
   is:
int snd_seq_open(snd_seq_t **seqp, const char * name, Int streams, Int mode);

   Hep! what is this "snd_seq_t **seqp"? We know that the asterisk is used to
   indicate a pointer - so what could mean a double asterisk? It's easy: a
   pointer to a pointer. This function snd_seq_open() uses the pointer notation
   to fill a value; this value is a pointer itself. Differently from the case
   of LDAP, where the function ldap_init() returns only one value, here this
   function returns two values. The return result of the function is an error
   code - all the ALSA functions use this scheme. A return result of zero means
   success. So to return more than a value, the function can only write some
   data to some location we specify, by using a pointer. The value it writes
   has type pointer, so the notation "double pointer" is used. So far so good.
   But can we translate this to Gambas? Yes and no. We need a pointer, and this
   is not a problem. Then we must take the address of this pointer, in order to
   obtain "a pointer to a pointer". Gambas3 can do that, Gambas2 can not.

   Let see the simpler way, only available in Gambas3. The VarPtr() function
   returns the address of a variable or, in other words, a pointer to that
   variable - and its name says so: VAR-PTR, "variable pointer". In gambas3 we
   would write:
PRIVATE EXTERN snd_seq_open(Pseq AS Pointer, name AS String, streams AS Integer
, mode AS Integer) AS Integer
...
PRIVATE AlsaHandler as Pointer
...
err = snd_seq_open(VarPtr(AlsaHandler), "default", 0, 0)

   The EXTERN declaration says that snd_seq_open() expects a pointer, which is
   true: snd_seq_open() expects a pointer to a pointer, which is anyway a
   pointer. So we declare a variable Alsahandler as pointer, and pass its
   address using VarPtr() which returns a pointer to the variable.

   In Gambas 2 this is not possible - we don't have VarPtr(). We must anyway
   declare a variable to hold the handle, like before, but then we can not get
   its address, or a pointer to it. We will attack the problem from another
   side. We need to find a location in memory to pass to alsa and, after that,
   go  to  peek in that location. In Gambas 2 the only way is the Alloc()
   function. By using Alloc(), we reserve a piece of memory somewhere, and
   obtain its address. This address is what we need to pass to snd_seq_open():
   a pointer contains an address. Well, can we start to write something? Yes:
' int snd_seq_open(snd_seq_t **seqp, const char * name, Int streams, Int mode);
PRIVATE EXTERN snd_seq_open(Pseq AS Pointer, name AS String, streams AS Integer
, mode AS Integer) AS Integereger
PRIVATE AlsaHandler as Pointer
...
DIM err AS Integer
DIM ret AS Pointer
ret = Alloc(4)  ' 4 is the size of a pointer in 32-bit systems; 8 for 64-bit sy
stems
err = snd_seq_open(ret, "default", 0, 0)

   When we want to open the connection and obtain a handler, we reserve some
   memory and pass its address, in order to have snd_seq_open() write useful
   data there. But then, how can we read that location to retrieve the handler?
   Here come the functionality of pointers in gambas. Pointers can work like
   streams - you can read from them and write to them. Actually, the memory of
   the computer is a file of memory cells, right? We can read a value from a
   pointer with:
READ #ret, AlsaHandler

   At this point, we succeeded. It's a little like an Odissey, but it is worth!
   We only must release the memory we reserved with Alloc(), so the Odissey is
   not yet over. That memory has been used in a temporary way, and we could
   neglect it, but if this operation was made many many times in a program, the
   program  continues to eat memory. Normally Gambas has automatic memory
   management, but in this case it cannot help because it doesn't know what we
   are doing with the memory, so we are responsible to free the memory when we
   are done with it:
Free(ret)

   There  are  other  reasons  to  use a pointer. Take the declaration of
   getloadavg(), a nice function that tells us how much our CPU has been busy
   in the last minute:
int getloadavg(double loadavg[], int nelem);

   This nice C language can even pass arrays to functions? Yes. And try to
   guess how it does it? Pointers again...
   In this case, the array passed to the function will be filled with one or
   more values, each signifying a different kind of load average; each value
   will be put in consecutive locations in the array. But C is not smart enough
   to know how big an array is, so the function can not know how many values to
   write. We have to tell the function, through the "nelem" parameter. To make
   it short, the correct declaration for this situation is this:
EXTERN getloadavg(ploadavg AS Pointer, nelem AS Integer) AS Intege      r

   We  need  to pass a pointer, because the function getloadavg expects a
   pointer, even if this could not be obvious by looking at its declaration.
   The pointer must point to free ram, because the function will fill the
   memory  pointed to by this pointer. Then, we will read the values and,
   lastly, we will fre the memory. Ax example usage is:
PUBLIC SUB get_load() AS Float
  DIM p AS Pointer
  DIM r AS Float
p = Alloc(8)
IF getloadavg(p, 1) <> 1 THEN
  Free(p)
  RETURN -1   ' error
ENDIF
READ #p, r
Free(p)
RETURN r
        END

   The subroutine is straightforward: we allocate 8 bytes because a gambas
   float is 8 bytes long. Then we call the getloadavg(), which will fill these
   8 bytes. Whether the operation succeeds or not, we must free the allocated
   memory. But, If the operation succeeded, first we must read the memory. This
   is why we have two "free(p)" in the subroutine. A more elegant way could be
   to use a FINALLY clause, but this way we are more close to the C spirit...

   getloadavg() returns the number of values read. Asking for only one value,
   it is legitimate to interpret a return result different from one as an
   error. If we asked for three, and only obtained two, we would have had a
   strange  situation  - something in between from a correct result and a
   failure. This and other funny things can be seen when trying to use some
   historical interfaces. For example, in some version of Unix there is not a
   clear  method  to read a file name. The function returns the number of
   character written, but no indication that the name is shorter than that. So
   you are only sure to have read the full name when you passed a buffer longer
   than the function result. But you have the function result *after* the call,
   not before! The typical usage is to take an arbitrary value, say 256, and do
   the first try. If it fails, you add another 256 bytes, and try again. And so
   on...

   Back to our getloadavg(), anyway. We used Alloc(8) because a gambas float is
   8 bytes long. And we used a gambas float in order to interface with a C
   double. But where is stated that a C double is 8 bytes long? In fact, there
   are out there machines where a double is 10 bytes. This is a serious issue,
   because the above subroutine will not work. We couuld allocate more memory,
   perhaps 64 bytes instead of 8: I am pretty sure that no computer exists wich
   use more than 64 bytes for a floating point number. But anyway, trying to
   read a 8-bytes value out of a 64-bytes value would yeld a nonsense. Perhaps
   is better to let a program crash, instead of giving the impression that it
   works. One question could arise... how can a C program work on so many
   different architectures? The answer is the following: because a new, perhaps
   different architecture, must have an omogeneous set of kernel, include files
   and  compiler. In a real C program you will never see a statement like
   "alloc(8)", but instead something like "alloc(sizeof(double))". The compiler
   knows the size of a double, and the keyword "sizeof" puts the knowledge of
   the compiler into the source program.

More on pointers

   Some better explanation is needed, at this point. The instruction READ
   #ret,... reads something from the location pointed to by the pointer "ret".
   It  is important to stress once again that this kind of things must be
   designed carefully. Working badly with pointers is one of the most common
   cause of failure of C programs and, when using pointers, Gambas can do no
   differently. In this case is easy, because we made our job in a few lines in
   a row.

   The semantics of the READ instruction in pointers resembles the one of
   STREAM, but with an important difference: while the stream is advanced
   automatically after a read or a write, the same operation on pointer does
   not. If our memory contained two variables to be read, one after the other,
   we had to advance the pointer by ourselves:
READ #mypointer, var1_4byte
mypointer += 4
READ #mypointer, var2_4byte

   As you can see, it is possible to treat a pointer like an integer. Using
   this mechanism, one can walk forward and back in memory to emulate what in C
   are called "struct". A "C struct" is a group of heterogeneous variables put
   side by side, which then can be treated like a single variable. Its closest
   counterpart in Gambas is, again, a class. Structures are often referenced by
   a pointer, especially when they are to be passed to a function. We will se
   later an alternative method to implement this in gambas, but now we are
   talking about pointers, so we will finish this topic. The C language has
   also "unions", which are an unknown thing to Gambas, and therefore they must
   be emulated using pointers (not completely true). Unions are composed of two
   or  more variables that share the same memory: writing to one variable
   modifies implicitly the others too: they are overlapped. The reason for this
   is to describe in a unique type different layouts. By combining struct and
   union,  complex  configurations can be generated, and this layouts are
   difficult not only to manage, but even to understand. To give an example, we
   will talk again about the ALSA sequencer. The sequencer works with events
   (mostly notes to be played) that have a time stamp to indicate "when" these
   events are to be played or carried out. This time stamp can be expressed in
   ticks, which is the traditional way related to the metronome. Ticks are
   normal integers. But ALSA goes further, and permits to use real-time time
   stamps, a much more precise indication, useful to synchronize music with
   other  things  (video, for example). This measurement is more precise,
   therefore it needs more memory to hold the bigger precision (two integers).
   So there are events having time specified with 4 bytes (an integer), and
   events having time specified with 8 bytes. They could have used simply two
   fields, respectively of 4 and 8 bytes, one after the other. But by using a
   union, they saved 4 bytes. The real memory reserved for time stamp is 8
   byte, big enough to hold either of the two values, but at a logic level
   these two values are mutually exclusive. All this is handled automatically
   by the C compiler. When playing with unions in Gambas, we must do all this
   by ourself.

A Gambas drum machine

   A concrete example about all we have seen until now is the ALSA library: a
   simple, very basic drum machine will be implemented in Gambas. First of all,
   what is a drum machine? It is a machine which emulates the combination of a
   drum player and a drum set. Many musicians use it, especially those who
   produce music all by themself. In the Gambas world, this is accomplished by
   using ALSA. ALSA is the Advanced Linux Sound Architecture, and its aim is to
   offer a complete set of functions to produce sounds and, hence, music. From
   the point of view of a computer, generic sound and music are two different
   things. If you play an MP3 file, ALSA will move the speakers as directed by
   the MP3 data, without knowing or analyzing anything. We are interested in
   another kind of interface - the sequencer interface. A sequencer copes with
   "events", which are "played" at the right times, using suitable parameters
   (or properties) for the event. If we think at a piano player, we can see
   that  he presses his keys, one or more together, at different moments.
   Simply, every keypress it's an event. The three most important things when
   pressing a key on a piano are: 1) when; 2) which key; 3) how strong. If you
   want to play two notes at the same time, you create two events having the
   same "timestamp". If you want to play a chord, you create three events
   having  the  same time, three different notes, and (probably) the same
   strongness. Then, you feed these events to the sequencer, and it will send
   them to something else which will produce the sounds. The sequencer does not
   care about producing sound: this can be produced by some software, or be
   outputted by a MIDI interface to some external musical instrument. If,
   instead of a piano, you say "I want trumpets", the three notes will be
   played by three trumpets. This interface does not specify "how long the
   notes play": they will sound until another event will say to stop. So a
   single note is actually done with two events: a NOTE-ON and a NOTE-OFF. In
   the case of drums, a note identifies a different piece of percussion: bass
   drum, snare drum, cymbals, maracas, bells, even whistles and much more.

   Music and computers have much in common. For example, a typical musical
   measure is divided in 4 quarters. Is the number four uncommon in computers?
   Keys on piano are numbered, and the strongness ("velocity") of a keypress
   can be expressed by a number, as well as the duration of a note. There are
   other values involved, for example the force a flute player uses to blow in
   his instrument (after the note has been started), but we will not go so
   deep. Only let me say that a good sequencer, combined with good hardware,
   can simulate surprisingly well an entire orchestra.

   The simple drum machine has a grid on the screen, and every cell of the grid
   represents a note: its row number specifies the note to be played (on a drum
   machine, different notes correspond to different pieces, or instruments).
   The column of a cell represents the time when the note will be played. The
   grid contains two measures which are played over and over - this is enough
   to construct a normal rythm. Every measure is divided in 4 quarters, and
   every quarter is divided further in four 16th's. The top row is a visual
   ruler, and the leftmost column is used to hear an instrument. Clicking in a
   cell toggles an "o" marker; to play the pattern click the button "Play
   grid". Other buttons produce some other sound, just to show simpler things
   like chords, legato's, arpeggio.

   To have the program produce sounds, the correct client/device and port (alsa
   terminology) must be written in the first two lines of FMain.class, and
   depends on the hardware installed. Issuing an "aconnect -ol" in a terminal
   shows the suitable devices. If a software synthetizer is present, like
   Timidity, probably it will show as "client 128". The MIDI out device could
   be number 16. The port number can probably be always 0. Another way to find
   out the correct numbers is to use an already working sequencer or MIDI
   player, like Kmidi, and peek at its midi configuration.

   The main reason to analyze this program is to look at a complete interface
   with an external library. Most of the issues have been presented already,
   but an important part not yet covered is how to cope with C structures using
   pointers.
   Instead of using pointers, an alternative way is to use declare variables in
   a class, and then pass an instance of that class to an external function;
   this is not covered here: the method would be better and clearer, but the
   pointers are more versatile. A yet better approach is possible in gambas3,
   which has native structures.

   Because the program is very alsa-specific, we will skip everything but the
   "event structure". Once all the things required by alsa are done (opening
   alsa, creating queues, ports, starting them and so on), only remains to
   construct events and send them to alsa, which will play them at the correct
   time. An event is defined by alsa like this:
snd_seq_event_type_t   type
unsigned char   flags
unsigned char   tag
unsigned char   queue
snd_seq_timestamp_t   time
snd_seq_addr_t   source
snd_seq_addr_t   dest
union {
   snd_seq_ev_note_t   note
   snd_seq_ev_ctrl_t   control
   snd_seq_ev_raw8_t   raw8
   snd_seq_ev_raw32_t   raw32
   snd_seq_ev_ext_t   ext
   snd_seq_ev_queue_control_t   queue
   snd_seq_timestamp_t   time
   snd_seq_addr_t   addr
   snd_seq_connect_t   connect
   snd_seq_result_t   result
}

   The first lines, before "union", are common to every kind of events; in
   fact, they contain the event "type", some "flags", a "tag", the "queue"
   where to enqueue the event, the "source" (who created the event?) and the
   "dest"  (to  whom  send  this  event?).  Let's  look at the firt line:
   "snd_seq_event_type_t type". The field is named "type", and its type is
   "snd_seq_event_type_t type". So we must inspect the documentation to find
   out how this type is made. We find:
typedef unsigned char snd_seq_event_type_t

   The line above says that "snd_seq_event_type_t" is an alias for "unsigned
   char". An unsigned char is a byte.
   The next three fields in the struct are flags tag and queue, all of type
   unsigned char, hence byte.
   Then the timestamp "time" is declared as "snd_seq_timestamp_t"; searching
   again for declaration, we find that it is a union containing either a midi
   tick (an unsigned int) or a struct which is composed by two unsigned int.
   The net result is that the length of this field is 2 unsigned ints, or 8
   bytes on 32-bit systems. The first part of an event is composed, by our
   point of view, of the following fields:
type_of_event                   a single byte
flags                                   a single byte
tag                                     a single byte
queue                           a single byte
timestamp, composed of:
  tick (int) or tv_sec          an integer
  tv_nsec                               an integer

   If  we  want  to fill the field "tick", we must point a pointer to the
   beginning of the event memory, then advance the pointer by 4 bytes, then
   write to the pointer the intended value (an integer).

   The CAlsa class allocates memory for just an event:
PUBLIC SUB alsa_open(myname AS String)
          ...
          ...
  ' alloc an event to work with. It is global to avoid alloc/dealloc burden
          ev = Alloc(SIZE_OF_SEQEV)

   and then manipulates this memory over and over before passing the event to
   alsa. The subroutine prepareev() clears the event and fills the common part.
   Here is its declaration:
PRIVATE SUB prepareev(type AS Byte, flags AS Byte, ts AS Integer) AS Pointer
        DIM p AS Pointer
        DIM i AS Integer

   The parameters of the function reflect what we are interested in - for
   example, we are not interested in the "tag" field, so we don't pass a value
   for it. The first step is to clear the event, to make sure that no unwanted
   data is there from before:
' clear the event
p = ev
FOR i = 1 TO SIZE_OF_SEQEV
  WRITE #p, 0, 1
  INC p
NEXT

   The pointer "p" is pointed to the beginning of the event with "p = ev". With
   a for-next a stream of zeroes is written out. The instruction "WRITE #p, 0,
   1" writes in the memory pointed by #p; it writes the value 0, using 1 byte.
   We must specify "1" (ie 1 byte), because the second parameter (0) is an
   integer constant, so gambas thinks it should write 4 bytes (or 8) - we force
   it to write a single byte. If instead of using a constant ("0"), we used a
   variable of type byte, gambas would have know the size of the variable (1
   byte), and we could have avoided to specify the size. But beware! This works
   with variables, but not with constants (a gambas 2 bug, I suppose).

   A better algorithm to clear the event would be to write 4 bytes at a time,
   and reduce the loop to 1/4. A still better way would be to simply rewrite
   fields we are interested in, and clear only the fields we know that are
   dirty.

   After clearing the event, we start to fill the relevant fields. Again, we
   point our pointer "p" to the correct place (we moved it, remember?), write a
   value, and move the pointer afterward:
p = ev
WRITE #p, type
p += 1          ' now p points to the flag field

   Notice that the "WRITE #p" has a slightly different syntax. This time a
   variable is written, so there is no need to tell gambas how many bytes to
   write. We want to write a single byte, and the variable "type" is 1 byte
   long.

   The rest of the routine is a repetition of what we have already seen. At the
   point of writing the timestamp, which is a C union, there is the following
   code:
WRITE #p, ts  ' timestamp
p += 4

   This  single  instruction  writes  the  first  of  the two integers of
   "snd_seq_timestamp_t time". Then:
ts = 0
WRITE #p, ts  ' 2^ part (realtime event)
p += 4

   Well, these three lines are not needed. We cleared all the memory before, so
   there is no need to set any field to zero. But we should anyway move the
   pointer. The two previous blocks of code could be as follows:
WRITE #p, ts  ' timestamp
p += 8

   The subroutine prepareev() is called by noteon() and noteoff(), which then
   continue to fill the event with own data. The noteon() subroutine is this:
PUBLIC SUB noteon(ts AS Integer, channel AS Byte, note AS Byte, velocity AS Byt
e)
  DIM p AS Pointer
  DIM err AS Integer
p = prepareev(SND_SEQ_EVENT_NOTEON, 0, ts)
WRITE #p, channel
INC p
WRITE #p, note
INC p
WRITE #p, velocity
err = snd_seq_event_output_buffer(handle, ev)

   The subroutine accepts a timestamp "ts", which says -when- to play the note,
   and refers to the time when the queue was started. A timestamp of zero, or
   anyway  a  value  less  than  the current time of the queue, is played
   immediately. If the timestamp is greater than the current queue time, then
   the  event will be played in the future, when the queue will reach the
   correct time. But alsa can also use relative timestamps, setting a flag in
   the event. The gambas CAlsa class uses this possibility embedding it in the
   timestamp directly. If the ts parameter to the prepareev() is set to a
   negative value, then the routine inverts its sign and sets the relative
   flag. In the main program, the routine btArpeggio_Click() produces three
   notes in succession by using this possibility:
PUBLIC SUB btArpeggio_Click()
  alsa.noteon(0, 0, 60, 100)
alsa.noteoff(-100, 0, 60, 100)
alsa.noteon(-100, 0, 64, 100)
alsa.noteoff(-200, 0, 64, 100)
alsa.noteon(-200, 0, 67, 100)
alsa.noteoff(-300, 0, 67, 100)
alsa.flush
        END

   To subroutine starts the first note at time 0, which means "now". After 100
   ticks, the note is shut off, and a new one is started (timestamp=-100 means
   "100 ticks after 0 -- 100 ticks after now"). And so on for the next notes.

   Given that playing notes is the most common task, and that to play a note
   one must create a note-on and a note-off, the CAlsa class implements a
   routine to do that with a single call. The following routine:
' 32 notes having their duration less than their spacing
' "staccato": every note terminates well before the next begins
PUBLIC SUB btStaccato_Click()
  DIM i AS Integer
FOR i = 1 TO 32
  ' relative timestamp=10, 20, 30... successive steps by 10
  ' but the notes have duration=5, not 10
  alsa.playnote(-10 * i, 0, 60 + i, 100, 5)
NEXT
alsa.flush
        END

   uses a single call to playnote(), which in turn generates internally two
   events.

   Lastly, to be precise, here is an explanation of the drum machine algorithm.

   The whole thing is to produce a stream of events, which will be played
   later. We must prepare a bunch of events in advance, so the hardware has
   data to work on. But a drum machine can be kept on for a long time, and we
   can not buffer all the needed events - we must supply a certain number of
   events  ahead  of  time, not too much and not too little. The internal
   "pointer" of the drum machine always is a musical measure ahead of the sound
   we are hearing. We can not predict reliably "when" new data will be needed,
   because the sequencer consumes the events basing itself on a timer that can
   be different from our. Without a feedback from the sequencer, it is nearly
   impossible to keep in sync. The problem is even more difficult if we want to
   have a visual feedback on what the sequencer is playing in a given moment.
   This is solved by adding, in the event stream, some event whose purpose is
   not to make sounds, but to come back to us: an echo. The sequencer receives
   this added events, and sends them back to us at the correct moment. When we
   see this echoes, we know at which point the sequencer is. The gambas drum
   machine sends an echo for every quarter, and uses this information, when it
   comes back, to give a visual feedback. These echo events can contain some
   user data - that datum is used to distinguish them; in the program, this can
   reveal a start of a measure, and in that condition a new measure is loaded
   (buffered in advance) to the sequencer.

   The problem, in this program, is that the normal alsa interface does not
   provide a callback to signal when an event is ready to be read (even if it
   did, gambas2 could not use it) . This is simulated by the CAlsa class, which
   raises a Gambas event when an alsa event of type "echo" has been read, but
   the CAlsa class itself uses polling to interrogate alsa. The frequency of
   this polling can be varied using the slider "poll freq" in the main program.
   Setting  this  frequency to low values should show an imprecise visual
   feedback of the drum machine, but the precision of the music should be
   unaffected.

How to interface Gambas to external libraries


== INTRODUCTION ==
There are lots of shared libraries available in a Linux system, capable of doing a lot of useful things, and many of those libraries can be used from Gambas using some of its features.


The first step to do is to find a suitable library to use for a given purpose; not all the libraries can be used, but the vast majority can. The prerequisite is that the library is written in plain C. Most libraries are written in C, while others are written in C++ and, perhaps, still other languages. This document will focus only about C libraries.


Once the intended library is found, its general logic must be understood in order to determine what is needed, and how this new stuff will be used by the final program. The full documentation of the library, and possibly some example, should be readed carefully. Libraries are not programs, and hence their philosophy is quite different. A program tends to contain only the subroutines required to do its job, while a library is what the name implies: a collection of subroutines, to be used many times, by many different programs. It is not uncommon to find, inside libraries, two or more subroutines which do the same thing, in a slightly different way. Libraries sometimes are written keeping in mind that they will be used by different languages, not only C: python, ruby, ocaml, many others, Gambas included. Libraries tend to encapsulate the details of a task inside a "handle", in a way similar to a Gambas object; but, they don't have properties and methods - everything is carried out by calling functions which these handles are passed to. If you think at a Gambas class with three properties and four methods, an external library implementing the same thing will have at least seven (three+four) subroutines, and probably a couple more to create and destroy the object. Other than this, there is not a big difference from setting a property and calling a function, the latter is simply a bit longer to write. To search for what we need, we must be prepared to read a lot of documentation, too often badly written (hey, apropos, how well do we document our software?).


== THE EXTERN DECLARATION ==
Extern declaration is simple. It is like a normal Gambas subroutine declaration, but preceded by "EXTERN". The EXTERN keyword says to gambas that the body of the procedure is not defined by the gambas program we are writing, but somewhere else (an external library). We must also specify which library to use: this is done by the clause "IN libraryXXX". Alternatively, you can use a separate LIBRARY statement: all the subsequent extern declarations will refer to this statement. Either "IN library" or "LIBRARY xxx" can specify a version number after a colon, and this is recommended.


Let's see an example, choosen because of its simplicity:



```
LIBRARY "libc:6"
EXTERN getgid() AS Integer
```

These two lines say that a function named "getgid" exists in the library "libc" version 6. This function takes no parameters, and returns an integer (the group ID).


The same thing can be written like this:



```
EXTERN getgid() AS Integer IN "libc:6"
```

Another example, slightly more complicated. This time we have parameters, and the last thing to say about the formal declaration:



```
' int kill(pid_t pid, int sig);
EXTERN killme(pid AS Integer, sig AS Integer) AS Integer IN "libc:6" EXEC "kill" 
```

The first line (the comment) shows the original declaration, and the second line the gambas one. We can note a number of things. First, what does the original declaration mean? It means "a function called kill returns an int, and it accepts two parameters. The first is named pid and its type is pid_t;  the second is named sig and its type is int". Contrary to Gambas, the C language puts the type of a variable before the variable instead of after.
Second, what in Gambas is called "Integer", in C is called "int". Third, what is "pid_t"? It's a type; we can understand it because it is written in a place where a type specifier is expected, and because ends with "_t" (underscore t).
Third, a new clause EXEC "kill" is used in the Gambas declaration. This is necessary because we want to use a function named kill, but KILL is a name already used by Gambas. So, in Gambas, we must name the function differently, but anyway we must indicate its true name inside the library. The declaration says "I declare an external function named killme, but its real name is kill". I chose the name killme because in the attached gambas example this function is used to kill the running program.


To be sincere I noticed that, even without renaming the function from kill to killme, the program was working the same. May be that this has something to do with case sensitivity - C is sensitive, and Gambas not, so there is still a difference between kill (lowercase) and KILL (uppercase). Anyway, when there is a possible name conflict, it is best to use this renaming technique.


== WARNING --- END OF THE EASY PART ==
//(just joking)//


At this point, several things must be noted. Most of the suitable libraries are written in C, which is a different language than Gambas. We will need to know at least a little of C declarations, in order to translate them to gambas. Referring to the last example, one could ask why I translated the pid_t type to integer. The simple and correct answer is "because on my system the pid_t type is actually an integer". This answer is really correct, but must be explained better, talking about agrumes (?). We can think about lemons and oranges, which both are agrumes, and are very similar: they weight more or less the same, and often can be interchanged; you can eat them directly, or squeeze them to drink their juice, but it is unlikely that you will put orange juice on your fried fish. In C, this is expressed by the fact that it is unlikely that you want to use the kill() function passing it an arbitrary integer. Surely, you will pass a process identifier (PID), which actually is an integer, but it is indicated more precisely as pid_t. In my motivation, I also said "on my system the pid_t type...". Yes, on my system - on most system, the type pid_t is an integer, but this could be different.


The final answer can be found by typing these two commands in a terminal:



```
grep -r pid_t /usr/include/* |grep "#define"
grep -r pid_t /usr/include/* |grep typedef
```

which will show the involuted way types are managed in C. This argument is way too complicated to go further; giving that Gambas runs on Linux, and presumably on desktop systems, we can consider that all the parameters passed to a function, and returned by it, will be either integer, or pointers - which are integer too, or strings - which are pointers that are integers. There can be also floating point numbers - float and double. The following table lists some of the types you can encounter in a C declaration, and the suitable type to be used in gambas:



```
C type			Gambas type
int			->	integer
long			->	long
float		->	single
double		->	float
xxxx*		->	pointer (the asterisk means exactly "pointer")
char*		->	pointer - but see later
other types	->	integer or pointer (depends on the declaration); see later
```

We will start to briefly introduce pointers, which are little used in Gambas. A pointer is an integer, but used very differently. The thing that more closely resembles a pointer in Gambas is a class instance. When you create, say, a Form in Gambas, a lot of data is stored somewhere in memory. That memory will hold all the specific settings of the form: its caption, its color, the list of all its children, and so on. The address of that block of memory is returned to your program, and stored into the variable which refers to the just created form:



```
MainForm = NEW Form()
```

That variable MainForm[  .t2t]is really a pointer: in only 4 (or 8) bytes it tracks a lot of data, stored somewhere in memory at a specific location (address). The memory is a long sequence of cells (bytes), each identified by a progressive number. A pointer contains the identifying number of a cell of memory (its address). In C, pointers are used for two reasons: the first is that passing only an address (a pointer contains an address), is much quicker than passing a lot of data; this is the same reason why Gambas instance variables like MainForm[  .t2t]are similar to pointers.


The second reason is when the called function should modify the variable we pass. For example, if we in Gambas wrote:



```
INPUT a	' where a is an integer
```

in C we would write:



```
void input(int *a);
...
input(&a);
```

The reason is that we want our INPUT command to fill our variable "a". In C, we must call input() and say to it where our variable is, in order to let it fill the variable. The ampersand "&" takes the address of the variable, and passes it to the function. The declaration of input() says "int *a", which states that "a" is not an integer, but a pointer to an integer, ie, the parameter says where to find the value, not the value itself.


== GAMBAS IMPLEMENTATION OF POINTERS ==
Gambas has the datatype Pointer, and a set of operations suitable for it. To use a pointer, a normal declaration is required like any other variable. Then, a value must be assigned to it. When using a normal variable, often you can assign a literal, for example you can write "a=3". With pointers, this is not advisable. A pointer gives access to any cell location in memory, but you should know in advance what location you are interested in, and that location must be the correct one for the intended purpose, otherwise Gambas or the operating system will get angry. This is much the same as saying that you can not write "MainForm = 3". You can write "MainForm = NEW Form()", or "MainForm = AnotherExistentForm", or "MainForm = NULL". So, a direct assignment to a pointer will always be to NULL, to another pointer, or to a call to some function returning a pointer. Just as a class instance variable like MainForm.


Sometimes an external function returns a pointer, and this pointer will be required in order to invoke subsequent calls to the external library. This case is much like creating a Form, and using its reference to operate on the form itself. In this case, the data behind (pointed by) the pointer is said to be "opaque": we can not see through something opaque, so we don't know, and we don't want to know. This is the simplest case; an example about this is the LDAP library. The first thing to do to interact with LDAP is to open a connection to a server. All the subsequent operations will be made on the connection created by a specific call. Things go like this:



```
LIBRARY "libldap:2"
PRIVATE EXTERN ldap_init(host AS String, port AS Integer) AS Pointer
PRIVATE ldapconn as Pointer
...
ldapconn = ldap_init(host, 389)
IF ldapconn = NULL THEN error.Raise("Can not connect to the ldap server")
```

As already seen, a LIBRARY is specified. Then, an EXTERN function is declared; this function is the one which must be called in order to do anything with ldap. The last two lines are the ones that, when executed, will open the connection and store its handle, or instance, for this connection. In this specific case, ldap_init() returns NULL if something goes wrong, so we can test for NULL to raise an error. Once obtained a handle to the connection, this handle must be specified on every subsequent call to the ldap library. For example, to delete an entry in the database, the following must be used:



```
PRIVATE EXTERN ldap_delete_s(ldconn AS Pointer, dn AS String) AS Integer
...
PUBLIC SUB remove(dn AS String) AS Integer
DIM res AS Integer
```


```
res = ldap_delete_s(ldapconn, dn)
```

Unfortunately, things are not always so simple. One of the reasons C uses a pointer, is to let the subroutine write some data in the location indicated by the calling parameters. Remaining in the initialization of a library, ALSA for example is different. To initiate a dialog with the alsa sequencer, a handle for the sequencer is needed. The C declaration for this function is:



```
int snd_seq_open(snd_seq_t **seqp, const char * name, Int streams, Int mode);
```

Hep! what is this "snd_seq_t **seqp"? We know that the asterisk is used to indicate a pointer - so what could mean a double asterisk? It's easy: a pointer to a pointer. This function snd_seq_open() uses the pointer notation to fill a value; this value is a pointer itself. Differently from the case of LDAP, where the function ldap_init() returns only one value, here this function returns two values. The return result of the function is an error code - all the ALSA functions use this scheme. A return result of zero means success. So to return more than a value, the function can only write some data to some location we specify, by using a pointer. The value it writes has type pointer, so the notation "double pointer" is used. So far so good. But can we translate this to Gambas? Yes and no. We need a pointer, and this is not a problem. Then we must take the address of this pointer, in order to obtain "a pointer to a pointer". Gambas3 can do that, Gambas2 can not.


Let see the simpler way, only available in Gambas3. The VarPtr() function returns the address of a variable or, in other words, a pointer to that variable - and its name says so: VAR-PTR, "variable pointer". In gambas3 we would write:



```
PRIVATE EXTERN snd_seq_open(Pseq AS Pointer, name AS String, streams AS Integer, mode AS Integer) AS Integer
...
PRIVATE AlsaHandler as Pointer
...
err = snd_seq_open(VarPtr(AlsaHandler), "default", 0, 0)
```

The EXTERN declaration says that snd_seq_open() expects a pointer, which is true: snd_seq_open() expects a pointer to a pointer, which is anyway a pointer. So we declare a variable Alsahandler as pointer, and pass its address using VarPtr() which returns a pointer to the variable.


In Gambas 2 this is not possible - we don't have VarPtr(). We must anyway declare a variable to hold the handle, like before, but then we can not get its address, or a pointer to it. We will attack the problem from another side. We need to find a location in memory to pass to alsa and, after that, go to peek in that location. In Gambas 2 the only way is the Alloc() function. By using Alloc(), we reserve a piece of memory somewhere, and obtain its address. This address is what we need to pass to snd_seq_open(): a pointer contains an address. Well, can we start to write something? Yes:



```
' int snd_seq_open(snd_seq_t **seqp, const char * name, Int streams, Int mode);
PRIVATE EXTERN snd_seq_open(Pseq AS Pointer, name AS String, streams AS Integer, mode AS Integer) AS Integereger
PRIVATE AlsaHandler as Pointer
...
DIM err AS Integer
DIM ret AS Pointer
```


```
ret = Alloc(4)	' 4 is the size of a pointer in 32-bit systems; 8 for 64-bit systems
err = snd_seq_open(ret, "default", 0, 0)
```

When we want to open the connection and obtain a handler, we reserve some memory and pass its address, in order to have snd_seq_open() write useful data there. But then, how can we read that location to retrieve the handler? Here come the functionality of pointers in gambas. Pointers can work like streams - you can read from them and write to them. Actually, the memory of the computer is a file of memory cells, right? We can read a value from a pointer with:



```
READ #ret, AlsaHandler
```

At this point, we succeeded. It's a little like an Odissey, but it is worth! We only must release the memory we reserved with Alloc(), so the Odissey is not yet over. That memory has been used in a temporary way, and we could neglect it, but if this operation was made many many times in a program, the program continues to eat memory. Normally Gambas has automatic memory management, but in this case it cannot help because it doesn't know what we are doing with the memory, so we are responsible to free the memory when we are done with it:



```
Free(ret)
```

There are other reasons to use a pointer. Take the declaration of getloadavg(), a nice function that tells us how much our CPU has been busy in the last minute:



```
int getloadavg(double loadavg[], int nelem);
```

This nice C language can even pass arrays to functions? Yes. And try to guess how it does it? Pointers again...
In this case, the array passed to the function will be filled with one or more values, each signifying a different kind of load average; each value will be put in consecutive locations in the array. But C is not smart enough to know how big an array is, so the function can not know how many values to write. We have to tell the function, through the "nelem" parameter. To make it short, the correct declaration for this situation is this:



```
EXTERN getloadavg(ploadavg AS Pointer, nelem AS Integer) AS Intege	r
```

We need to pass a pointer, because the function getloadavg expects a pointer, even if this could not be obvious by looking at its declaration. The pointer must point to free ram, because the function will fill the memory pointed to by this pointer. Then, we will read the values and, lastly, we will fre the memory. Ax example usage is:



```
PUBLIC SUB get_load() AS Float
  DIM p AS Pointer
  DIM r AS Float
```


```
p = Alloc(8)
IF getloadavg(p, 1) <> 1 THEN
  Free(p)
  RETURN -1   ' error
ENDIF 
```


```
READ #p, r
Free(p)
RETURN r
	END
```

The subroutine is straightforward: we allocate 8 bytes because a gambas float is 8 bytes long. Then we call the getloadavg(), which will fill these 8 bytes. Whether the operation succeeds or not, we must free the allocated memory. But, If the operation succeeded, first we must read the memory. This is why we have two "free(p)" in the subroutine. A more elegant way could be to use a FINALLY clause, but this way we are more close to the C spirit...


getloadavg() returns the number of values read. Asking for only one value, it is legitimate to interpret a return result different from one as an error. If we asked for three, and only obtained two, we would have had a strange situation - something in between from a correct result and a failure. This and other funny things can be seen when trying to use some historical interfaces. For example, in some version of Unix there is not a clear method to read a file name. The function returns the number of character written, but no indication that the name is shorter than that. So you are only sure to have read the full name when you passed a buffer longer than the function result. But you have the function result *after* the call, not before! The typical usage is to take an arbitrary value, say 256, and do the first try. If it fails, you add another 256 bytes, and try again. And so on...


Back to our getloadavg(), anyway. We used Alloc(8) because a gambas float is 8 bytes long. And we used a gambas float in order to interface with a C double. But where is stated that a C double is 8 bytes long? In fact, there are out there machines where a double is 10 bytes. This is a serious issue, because the above subroutine will not work. We couuld allocate more memory, perhaps 64 bytes instead of 8: I am pretty sure that no computer exists wich use more than 64 bytes for a floating point number. But anyway, trying to read a 8-bytes value out of a 64-bytes value would yeld a nonsense. Perhaps is better to let a program crash, instead of giving the impression that it works. One question could arise... how can a C program work on so many different architectures? The answer is the following: because a new, perhaps different architecture, must have an omogeneous set of kernel, include files and compiler. In a real C program you will never see a statement like "alloc(8)", but instead something like "alloc(sizeof(double))". The compiler knows the size of a double, and the keyword "sizeof" puts the knowledge of the compiler into the source program.


== More on pointers ==
Some better explanation is needed, at this point. The instruction READ #ret,... reads something from the location pointed to by the pointer "ret". It is important to stress once again that this kind of things must be designed carefully. Working badly with pointers is one of the most common cause of failure of C programs and, when using pointers, Gambas can do no differently. In this case is easy, because we made our job in a few lines in a row.


The semantics of the READ instruction in pointers resembles the one of STREAM, but with an important difference: while the stream is advanced automatically after a read or a write, the same operation on pointer does not. If our memory contained two variables to be read, one after the other, we had to advance the pointer by ourselves:



```
READ #mypointer, var1_4byte
mypointer += 4
READ #mypointer, var2_4byte
```

As you can see, it is possible to treat a pointer like an integer. Using this mechanism, one can walk forward and back in memory to emulate what in C are called "struct". A "C struct" is a group of heterogeneous variables put side by side, which then can be treated like a single variable. Its closest counterpart in Gambas is, again, a class. Structures are often referenced by a pointer, especially when they are to be passed to a function. We will se later an alternative method to implement this in gambas, but now we are talking about pointers, so we will finish this topic. The C language has also "unions", which are an unknown thing to Gambas, and therefore they must be emulated using pointers (not completely true). Unions are composed of two or more variables that share the same memory: writing to one variable modifies implicitly the others too: they are overlapped. The reason for this is to describe in a unique type different layouts. By combining struct and union, complex configurations can be generated, and this layouts are difficult not only to manage, but even to understand. To give an example, we will talk again about the ALSA sequencer. The sequencer works with events (mostly notes to be played) that have a time stamp to indicate "when" these events are to be played or carried out. This time stamp can be expressed in ticks, which is the traditional way related to the metronome. Ticks are normal integers. But ALSA goes further, and permits to use real-time time stamps, a much more precise indication, useful to synchronize music with other things (video, for example). This measurement is more precise, therefore it needs more memory to hold the bigger precision (two integers). So there are events having time specified with 4 bytes (an integer), and events having time specified with 8 bytes. They could have used simply two fields, respectively of 4 and 8 bytes, one after the other. But by using a union, they saved 4 bytes. The real memory reserved for time stamp is 8 byte, big enough to hold either of the two values, but at a logic level these two values are mutually exclusive. All this is handled automatically by the C compiler. When playing with unions in Gambas, we must do all this by ourself.


== A Gambas drum machine ==
A concrete example about all we have seen until now is the ALSA library: a simple, very basic drum machine will be implemented in Gambas. First of all, what is a drum machine? It is a machine which emulates the combination of a drum player and a drum set. Many musicians use it, especially those who produce music all by themself. In the Gambas world, this is accomplished by using ALSA. ALSA is the Advanced Linux Sound Architecture, and its aim is to offer a complete set of functions to produce sounds and, hence, music. From the point of view of a computer, generic sound and music are two different things. If you play an MP3 file, ALSA will move the speakers as directed by the MP3 data, without knowing or analyzing anything. We are interested in another kind of interface - the sequencer interface. A sequencer copes with "events", which are "played" at the right times, using suitable parameters (or properties) for the event. If we think at a piano player, we can see that he presses his keys, one or more together, at different moments. Simply, every keypress it's an event. The three most important things when pressing a key on a piano are: 1) when; 2) which key; 3) how strong. If you want to play two notes at the same time, you create two events having the same "timestamp". If you want to play a chord, you create three events having the same time, three different notes, and (probably) the same strongness. Then, you feed these events to the sequencer, and it will send them to something else which will produce the sounds. The sequencer does not care about producing sound: this can be produced by some software, or be outputted by a MIDI interface to some external musical instrument. If, instead of a piano, you say "I want trumpets", the three notes will be played by three trumpets. This interface does not specify "how long the notes play": they will sound until another event will say to stop. So a single note is actually done with two events: a NOTE-ON and a NOTE-OFF. In the case of drums, a note identifies a different piece of percussion: bass drum, snare drum, cymbals, maracas, bells, even whistles and much more.


Music and computers have much in common. For example, a typical musical measure is divided in 4 quarters. Is the number four uncommon in computers? Keys on piano are numbered, and the strongness ("velocity") of a keypress can be expressed by a number, as well as the duration of a note. There are other values involved, for example the force a flute player uses to blow in his instrument (after the note has been started), but we will not go so deep. Only let me say that a good sequencer, combined with good hardware, can simulate surprisingly well an entire orchestra.


The simple drum machine has a grid on the screen, and every cell of the grid represents a note: its row number specifies the note to be played (on a drum machine, different notes correspond to different pieces, or instruments). The column of a cell represents the time when the note will be played. The grid contains two measures which are played over and over - this is enough to construct a normal rythm. Every measure is divided in 4 quarters, and every quarter is divided further in four 16th's. The top row is a visual ruler, and the leftmost column is used to hear an instrument. Clicking in a cell toggles an "o" marker; to play the pattern click the button "Play grid". Other buttons produce some other sound, just to show simpler things like chords, legato's, arpeggio.


To have the program produce sounds, the correct client/device and port (alsa terminology) must be written in the first two lines of FMain.class, and depends on the hardware installed. Issuing an "aconnect -ol" in a terminal shows the suitable devices. If a software synthetizer is present, like Timidity, probably it will show as "client 128". The MIDI out device could be number 16. The port number can probably be always 0. Another way to find out the correct numbers is to use an already working sequencer or MIDI player, like Kmidi, and peek at its midi configuration.


The main reason to analyze this program is to look at a complete interface with an external library. Most of the issues have been presented already, but an important part not yet covered is how to cope with C structures using pointers.
Instead of using pointers, an alternative way is to use declare variables in a class, and then pass an instance of that class to an external function; this is not covered here: the method would be better and clearer, but the pointers are more versatile. A yet better approach is possible in gambas3, which has native structures.


Because the program is very alsa-specific, we will skip everything but the "event structure". Once all the things required by alsa are done (opening alsa, creating queues, ports, starting them and so on), only remains to construct events and send them to alsa, which will play them at the correct time. An event is defined by alsa like this:



```
snd_seq_event_type_t   type
unsigned char   flags
unsigned char   tag
unsigned char   queue
snd_seq_timestamp_t   time
snd_seq_addr_t   source
snd_seq_addr_t   dest
union {
   snd_seq_ev_note_t   note
   snd_seq_ev_ctrl_t   control
   snd_seq_ev_raw8_t   raw8
   snd_seq_ev_raw32_t   raw32
   snd_seq_ev_ext_t   ext
   snd_seq_ev_queue_control_t   queue
   snd_seq_timestamp_t   time
   snd_seq_addr_t   addr
   snd_seq_connect_t   connect
   snd_seq_result_t   result
} 
```

The first lines, before "union", are common to every kind of events; in fact, they contain the event "type", some "flags", a "tag", the "queue" where to enqueue the event, the "source" (who created the event?) and the "dest" (to whom send this event?). Let's look at the firt line: "snd_seq_event_type_t type". The field is named "type", and its type is "snd_seq_event_type_t type". So we must inspect the documentation to find out how this type is made. We find:



```
typedef unsigned char snd_seq_event_type_t
```

The line above says that "snd_seq_event_type_t" is an alias for "unsigned char". An unsigned char is a byte.
The next three fields in the struct are flags tag and queue, all of type unsigned char, hence byte.
Then the timestamp "time" is declared as "snd_seq_timestamp_t"; searching again for declaration, we find that it is a union containing either a midi tick (an unsigned int) or a struct which is composed by two unsigned int. The net result is that the length of this field is 2 unsigned ints, or 8 bytes on 32-bit systems. The first part of an event is composed, by our point of view, of the following fields:



```
type_of_event			a single byte
flags					a single byte
tag					a single byte
queue				a single byte
timestamp, composed of:
  tick (int) or tv_sec		an integer
  tv_nsec				an integer
```

If we want to fill the field "tick", we must point a pointer to the beginning of the event memory, then advance the pointer by 4 bytes, then write to the pointer the intended value (an integer).


The CAlsa class allocates memory for just an event:



```
PUBLIC SUB alsa_open(myname AS String)
  	  ...
  	  ...
  ' alloc an event to work with. It is global to avoid alloc/dealloc burden
  	  ev = Alloc(SIZE_OF_SEQEV)
```

and then manipulates this memory over and over before passing the event to alsa. The subroutine prepareev() clears the event and fills the common part. Here is its declaration:



```
PRIVATE SUB prepareev(type AS Byte, flags AS Byte, ts AS Integer) AS Pointer
  	DIM p AS Pointer
  	DIM i AS Integer
```

The parameters of the function reflect what we are interested in - for example, we are not interested in the "tag" field, so we don't pass a value for it. The first step is to clear the event, to make sure that no unwanted data is there from before:



```
' clear the event
p = ev
FOR i = 1 TO SIZE_OF_SEQEV
  WRITE #p, 0, 1
  INC p
NEXT 
```

The pointer "p" is pointed to the beginning of the event with "p = ev". With a for-next a stream of zeroes is written out. The instruction "WRITE #p, 0, 1" writes in the memory pointed by #p; it writes the value 0, using 1 byte. We must specify "1" (ie 1 byte), because the second parameter (0) is an integer constant, so gambas thinks it should write 4 bytes (or 8) - we force it to write a single byte. If instead of using a constant ("0"), we used a variable of type byte, gambas would have know the size of the variable (1 byte), and we could have avoided to specify the size. But beware! This works with variables, but not with constants (a gambas 2 bug, I suppose).


A better algorithm to clear the event would be to write 4 bytes at a time, and reduce the loop to 1/4. A still better way would be to simply rewrite fields we are interested in, and clear only the fields we know that are dirty.


After clearing the event, we start to fill the relevant fields. Again, we point our pointer "p" to the correct place (we moved it, remember?), write a value, and move the pointer afterward:



```
p = ev
WRITE #p, type
p += 1		' now p points to the flag field
```

Notice that the "WRITE #p" has a slightly different syntax. This time a variable is written, so there is no need to tell gambas how many bytes to write. We want to write a single byte, and the variable "type" is 1 byte long.


The rest of the routine is a repetition of what we have already seen. At the point of writing the timestamp, which is a C union, there is the following code:



```
WRITE #p, ts  ' timestamp
p += 4
```

This single instruction writes the first of the two integers of "snd_seq_timestamp_t   time". Then:



```
ts = 0
WRITE #p, ts  ' 2^ part (realtime event)
p += 4
```

Well, these three lines are not needed. We cleared all the memory before, so there is no need to set any field to zero. But we should anyway move the pointer. The two previous blocks of code could be as follows:



```
WRITE #p, ts  ' timestamp
p += 8
```

The subroutine prepareev() is called by noteon() and noteoff(), which then continue to fill the event with own data. The noteon() subroutine is this:



```
PUBLIC SUB noteon(ts AS Integer, channel AS Byte, note AS Byte, velocity AS Byte)
  DIM p AS Pointer
  DIM err AS Integer
```


```
p = prepareev(SND_SEQ_EVENT_NOTEON, 0, ts)
WRITE #p, channel
INC p
WRITE #p, note
INC p
WRITE #p, velocity
```


```
err = snd_seq_event_output_buffer(handle, ev)
```

The subroutine accepts a timestamp "ts", which says -when- to play the note, and refers to the time when the queue was started. A timestamp of zero, or anyway a value less than the current time of the queue, is played immediately. If the timestamp is greater than the current queue time, then the event will be played in the future, when the queue will reach the correct time. But alsa can also use relative timestamps, setting a flag in the event. The gambas CAlsa class uses this possibility embedding it in the timestamp directly. If the ts parameter to the prepareev() is set to a negative value, then the routine inverts its sign and sets the relative flag. In the main program, the routine btArpeggio_Click() produces three notes in succession by using this possibility:



```
PUBLIC SUB btArpeggio_Click()
  alsa.noteon(0, 0, 60, 100)
```


```
alsa.noteoff(-100, 0, 60, 100)
alsa.noteon(-100, 0, 64, 100)
```


```
alsa.noteoff(-200, 0, 64, 100)
alsa.noteon(-200, 0, 67, 100)
```


```
alsa.noteoff(-300, 0, 67, 100)
```


```
alsa.flush
	END
```

To subroutine starts the first note at time 0, which means "now". After 100 ticks, the note is shut off, and a new one is started (timestamp=-100 means "100 ticks after 0 -- 100 ticks after now"). And so on for the next notes.


Given that playing notes is the most common task, and that to play a note one must create a note-on and a note-off, the CAlsa class implements a routine to do that with a single call. The following routine:



```
' 32 notes having their duration less than their spacing
' "staccato": every note terminates well before the next begins
PUBLIC SUB btStaccato_Click()
  DIM i AS Integer
```


```
FOR i = 1 TO 32
  ' relative timestamp=10, 20, 30... successive steps by 10
  ' but the notes have duration=5, not 10
  alsa.playnote(-10 * i, 0, 60 + i, 100, 5)
NEXT
alsa.flush
	END
```

uses a single call to playnote(), which in turn generates internally two events.


Lastly, to be precise, here is an explanation of the drum machine algorithm.


The whole thing is to produce a stream of events, which will be played later. We must prepare a bunch of events in advance, so the hardware has data to work on. But a drum machine can be kept on for a long time, and we can not buffer all the needed events - we must supply a certain number of events ahead of time, not too much and not too little. The internal "pointer" of the drum machine always is a musical measure ahead of the sound we are hearing. We can not predict reliably "when" new data will be needed, because the sequencer consumes the events basing itself on a timer that can be different from our. Without a feedback from the sequencer, it is nearly impossible to keep in sync. The problem is even more difficult if we want to have a visual feedback on what the sequencer is playing in a given moment. This is solved by adding, in the event stream, some event whose purpose is not to make sounds, but to come back to us: an echo. The sequencer receives this added events, and sends them back to us at the correct moment. When we see this echoes, we know at which point the sequencer is. The gambas drum machine sends an echo for every quarter, and uses this information, when it comes back, to give a visual feedback. These echo events can contain some user data - that datum is used to distinguish them; in the program, this can reveal a start of a measure, and in that condition a new measure is loaded (buffered in advance) to the sequencer.


The problem, in this program, is that the normal alsa interface does not provide a callback to signal when an event is ready to be read (even if it did, gambas2 could not use it) . This is simulated by the CAlsa class, which raises a Gambas event when an alsa event of type "echo" has been read, but the CAlsa class itself uses polling to interrogate alsa. The frequency of this polling can be varied using the slider "poll freq" in the main program. Setting this frequency to low values should show an imprecise visual feedback of the drum machine, but the precision of the music should be unaffected.

It is explicitely said that "WRITE #Pointer" is not supported anymore in 
Gambas 3, in the WRITE documentation page. And so on for the READ instruction.

Mmm. it could be a bug in Gambas 2. A workaround would be using CByte() 
explicitely.

The Gambas 3 structures were implemented for the use of extern C structures. 
Moreover, in Gambas 3, you can now use Gambas functions as C function pointer  
(as known as "callbacks") almost transparently.

I guess you are using the gb.sdl.sound component.

Can you provide the MP3 that are not played correctly?

I found the workaround for the situation:
The above mentioned happens when I record a sound with Audacity (e.g.
YouTube)  and save as MP3 with 48.000Hz as project frequency (Audigy-2).
When I convert the sound with Audacity to 44.000 Hz, then convert the new
MP3 to WAV with Nautilus-script, and finally reconvert with the same script
to MP3 the problem disappears. At least I wrote down how to reproduce the
bug.

I've changed the topic header - but just to comment here, this is a long 
standing and inconsistant problem I've noticed in the linux environment 
gambas.

I has has happened more to more when I do ctrl C or use a menu with a copy 
option, then switch immediately to gambas and do a Ctrl V or visa-versa.

On the occasions it dosn't work, either nothing pastes, or what pastes was 
from some previous copy.

Can't reproduce it  not common - but just repeating that it does exist. My two 
linux distro's I've experienced this in as ARCH and KUbuntu.

Mmm... this is an excerpt from the first lines of "External-howto.html",

Both are contained in the attached files - the C declaration, along with 
explanation and unrolling of structs/typedef/#define and so on, in the 
document; the Gambas class trying to emulate the C declaration, in the 
project "Gambas2-Drummachine....". For your convenience, I will repeat 
both at the end of this email.

Sorry, I think that it is not so clear. "No more supported", or 
equivalent semantics, is totally absent from the page. It is true that 
there is a frame specifying the syntax for READ in Gambas3, but it 
speaks only about "READ #Stream". This makes me think that the "READ 
#Stream" syntax or behavior changed, not necessarily that pointers are 
no more valid. Perhaps would be better to say something more in the 
first frame, the one just below the title of the page: "WARNING! The 
syntax has changed in Gambas 3. READ/WRITE with pointers is no more 
supported in Gambas 3. See below."

You said that you removed this syntax because of possible problems with 
memory alignment. What about BytePtr(), SinglePtr() and the alike? Do 
they not suffer from the same problem? (Just a curiosity).

I know... it was me that kindly requested that feature, I suppose... :-)
And, apropos...
I saw that alsa does not really provides a callback - there is something 
about in an undocumented source (an utility for alsa). Instead, what 
alsa provides, is a file descriptor which can be poll()ed or select()ed. 
Then I have seen a source for QT, which uses this capability. It seems 
the QT has a way to pass it a file descriptor, so it can raise events 
intermixed with GUI events. Glib too has something similar. I thought to 
use or fool some gambas stream to obtain the same result... but perhaps 
you have a better idea.

Now let us see the problem about the alsa (musical) event structure. 
Giving that I made it to work, probably I did understand that structure 
and, if I only had a simple way to debug my gambas implementation, I 
would have had success. The alsa declaration is:

    snd_seq_event_type_t    type
    unsigned char           flags
    unsigned char           tag
    unsigned char           queue
    snd_seq_timestamp_t     time
    snd_seq_addr_t          source
    snd_seq_addr_t          dest
    union {
       snd_seq_ev_note_t    note
        ...

The first field, type, is a byte. The fifth field, time, is a union 
having a total length of two ints, eight bytes in total.
The source and dest fields are struct composed of two bytes each. After 
this fields, that are common to every alsa event, comes a specialized 
part for every different event. I only used the snd_seq_ev_note_t.

My gambas translation is:

    ' Gambas class file

    ' object data to simulate a C struct

    type AS Byte            '    snd_seq_event_type_t type
    flags AS Byte           '    unsigned char flags
    tag AS Byte             '    unsigned char tag
    PUBLIC queue AS Byte    '    unsigned char queue
    time_tick AS Integer    '    snd_seq_timestamp_t Time
    time_dummy AS Integer   '    snd_seq_timestamp_t Time (2 part of union)
    PUBLIC sourceq AS Byte  '    snd_seq_addr_t source (source client)
    PUBLIC sourcep AS Byte  '    snd_seq_addr_t source (source port)
    PUBLIC destq AS Byte    '    snd_seq_addr_t dest (dest client)
    PUBLIC destp AS Byte    '    snd_seq_addr_t dest (dest port)

    ' note on fields of union {   snd_seq_ev_note_t note ...
    channel AS Byte
    note AS Byte
    velocity AS Byte

    ' a few bytes as filler
    dummy1 AS Integer
    dummy2 AS Integer
    ...

If you can use MIDI, or you have a soft synth like timidity, you can try 
to run the project to see what is going on.
In FMain.class, in the subroutine btLegato2_Click(), you find:

    ' alsa.playnoteobj(-10 * i, 0, 60 + i, 100, 20)
    alsa.playnote(-10 * i, 0, 60 + i, 100, 20)

Decomment the first line and comment-out the second. The second line 
prepares a C struct as the one above, using pointers to write in a 
memory region previously allocated, once for the whole life of the 
running program. The first line instead, tries to do the same by using a 
gambas class. An instance of that class is created once, and then 
repeatedly written to to set the various fields; finally, a pointer to 
the instance is passed to alsa, but alsa replies with "invalid 
argument". My machine is a 32-bit AMD Duron, with a Debian stable 
distribution; the test was made with gambas 2.0.0.

Best regards,
Doriano

Salut,

I'v that troubles also, but I think in my case it's my KVM and/or the
KVM and VMware-Workstation because I'v that on my Ubuntu 8.04 (a real
computer) but also on Mandriva  2010.1 (also a real computer) and on all
VMware-Workstations from SuSE 9.x over BSD to Windows (worst since
Office 2007).

I do not belief, that "Computers" or "OS" have problems with Ctrl+C/+V

Subject: [Gambas-user] Find method and string question
Message-ID: <4C74FA6F.7080606@...221...>

Hi folks,

Just to make sure I have got it right:

Does .Find only find whole strings, not part-strings?

Say flx[5] contains "This is a string" and I search for

flx.Find("string", gb.Text)

it doesn't find it (but should find number 5).

If flx[5] contains only "string", it is found.

At least it appears so, my string here is divided not by whitespaces but 
by chr$(6), and I was searching for one of the part-strings. It didn't 
recognize it, so that's why I ask just to make sure.

Regards

Rolf

Hi!
I would like to have TimeLeft property to timer object.
It is only missing thing which forces me to write my own delay function.

So, nothing very important, but if this is easy to implement...

That is explicitetly mentioned in the READ & WRITE documentation page. See the

Actually the interpreter can do it, but there is no function in the language

Note that 'WRITE #p, 0, 1' does not write one byte, but only the integer 0 on 
four bytes. You must do 'WRITE #p, chr$(0), 1'

WRITE #p, outq writes four bytes as outq is an integer, not one byte.

And so on... I think you must check all your use of the WRITE instruction, 
which write a number of bytes that depends on the datatype of its second 
argument.

In Gambas 3, you say explicitely what datatype you want to write (WRITE 
#Stream, Expression As Datatype).

As for the use of an object instead of a memory allocation, I don't know. I 
must study that in detail. When passing an object to an extern function, the 
extern function receives the memory address of the first field. So now I must 
check that all datatypes match, and that there is no alignment problem.

This time I would use it with trayicon (mouse over) to inform user about
when next event is going to occur.
There was an other reason long time ago when I needed that... I just
couldn't remember.
I wonder if it was something more general...

In Europe we do it like that. All calendars begin with Monday. Sunday is 
part of the weekend. I know that in Germany before  we had a big 
discussion about it, but then we switched to the current system. Must 
have been in the sixties or early seventies, just the time when I 
started school, so I heard about the final discussion.

But: isn't that a matter of the locale? If you say KDE for instance that 
you are in the US, all calendar apps should recognize this.

i just want to say that i've queried something like that 3 week ago :)

Something that allow to delay mouse events ... for exemple for mouse
there is two case ...

Mouse is in the widget during a time ... or mouse button is pressed
during a time ... and for keyboard  just button is pressed during a
time.

But how to make that usable ?

i use timer for that

On mouse down -> timer.start

On mouse up -> timer stop
on mouse leave -> timer stop

timer timer -> do what you need


timer.delay = 1000

It should be a valid archive! I think that is a bug in maverick.

Apparently the first day of the week is Monday everywhere but in US! If 
somebody can confirm...

I will make a change in Gambas 3, and if I have time, I will try to backport 
it to Gambas 2.

Hi Rolf,
Thanks for the reply, but changing KDE locale didn't change the DateChooser display.

I am writing an application to generate the Bible Calendar for this year and more.
The user plugs in dates of New Moons sightings to generate a current Biblical month.

The user selects (Monday-Sunday DateChooser) new moon dates on DateChooser,
then the Biblical Calendar is generated and displayed (Sunday-Sabbath).
It doesn't change the generated calendar results - but it can confuse the users.
Thanks, Tom

Subject: [Gambas-user] Question about collections and inheritance
Message-ID: <AANLkTimu=vWPV0T6fJsp+ix_Qkyo+nj4RO6WPK3XZ=PG@...627...>

   Hi all.

   I'm trying to code a very basic Xml Excel Generator, and I'm workin with
a collection. This is my code:

' Gambas class file

Inherits Collection

Public Function Add($ID As String) As Style

  Dim $style As New Style($ID)

  Super.Add($style, $ID)

  Return $style

End

Public Function _GetXml() As String

  Dim $style As Style
  Dim $text As String = "\t<s:Styles>\n"

  For Each $style In Me
    $text &= $style._GetXml() & "\n"
  Next

  $text &= "\t</s:Styles>"
  Return $text

End

   Style is another class I have. My class inherits the Collection class and
I override the Add function. All of this works fine, my question is about
another Collection functionality:

    With a normal Collection we can do something like this:

  Dim $col As Collection
  $col.Add("My value", "key")
  Print *$col["key"]*

   I can access to my item whit his "key". How can I override this
functionality in my class, because Gambas return me a Variant data type
element and I want to return my own data type, my Style class.

   Thanks.

P.S. Sorry my english, I trying to learn it but I'm still newbie

Very strange. A friend of us picked the same document from the gambas 
list, and put it on the italian site of gambas (www.gambas-it.org). 
Anyway, I attach a tarred copy of the new document, which contains 
corrections.

My copy of the documentation is different. With all evidence, a 
correction about this topic was added after I downloaded the gambas 
sources from sourceforge. Anyway, the important thing is that now the 
documentation is correct.

I corrected the above errors, and attach the revised project.
It worked anyway, because the extraneous bytes written after the 
intended ones, were afterwards rewritten with correct values. Perhaps 
the compiler could reject statements like "write #p, 0, 1", or perhaps 
gambas2 is going to museum in favor of gambas3.

In a previous email I said that by declaring a constant as a byte, and 
then writing it out with a "write #pointer...", 4 bytes were written 
instead of one. This is not totally true - I did'nt verified. What is 
true, instead, is that declaring a constant as byte, and then writing it 
out to a stream, 4 bytes are written. This was verified in an old 
temptative of the drum machine, where OSS was used instead of alsa, and 
a gambas stream (file) was used to write to the file /dev/sequencer2.

Doriano Blengino

Yep. According to Wikipedia, Sunday is the first day of the week mainly in 
monotheistic religions. 

So I cannot rely on the country! I must let the programmer decide, and provide 
a property in the DateChooser control. Or better a global property in the 
System class.

Hi. I attached a little example.

The GTK version is needed if you're under a 'gtk' desktop, but it works
well even under qt. So the GTK version is the good one; it has two more lines 
of code because the NOT-gtk version crashes the Gambas IDE. Is it a bug, 
Benoit?

I don't see any difference in the source code of both projects. Both work as 
expected. Are you sure that you sent the good files?

You have to override the _get() method. Something like that I presume:

Public sub _get(Id As String) As Style

  Return Super[Id]

End

Sorry, I messed up things. Anyway the two lines are these:

TabStrip1[TabStrip1.Count - 1].Text = "Tab " & (TabStrip1.Count - 1)
TabStrip1.Index = TabStrip1.Count - 1

With gb.qt you *don't need* these two lines to create a 'New Tab' and put 
focus on it. It works perfectly.

If you remove these two lines gb.qt still works, but gb.gtk crashes the IDE.
Attached the fixed example. Try selecting gb.gtk and you get a crash, at least 
on my system. 

Gambas 2.20
Qt 3.3.8b
Gtk 2.12.12 

Saluti,

Stefano

Subject: [Gambas-user] A minor bug with TabStrip Control  - GTK
Message-ID: <1283049918.2807.70.camel@...1975...>


Greetings all,

I think I have found a minor bug with the TabStrip control where the
Tabs remain 'invisible'  when you toggle the visibility mode while it is
in the foreground of another control.
I could not find this bug listed anywhere - it may have already been
fixed in V3.

Gambas version used in testing 2.20.
Issues only occurs with gb.gtk - gb.qt seems to be fine.

[To Test set project properties to gb.gtk]

I created a standard form with a:
Gridview control
TabStrip control 
Label control in the body of Tab[0]  (to test visibility of controls in
TabStrip body).
Button

I set the arrangement of the TabStrip control to - 'Bring To Foreground'
in the GUI.

The area of the Tabs in the TabStrip control must be over the background
control.

--------------------------------------------------------------------------------------
[Code used to display bug.]

PUBLIC SUB Form_Open()
TabStrip1.Visible = FALSE
END

PUBLIC SUB Button1_Click()

  TabStrip1.Visible = TRUE

END
--------------------------------------------------------------

When you click on Button1 the body of the TabStrip becomes visible - the
label control in Tab[0] is visible.
The tabs ( any number ) remain invisible provided they are over the
background control.

Note # If you add the line Gridview1.visible = FALSE to the Button1
Click event , the tabs of the TabStrip control are then visible at run
time.

I found that every control I tested as the background control ( Panel,
Text box, Frame...) produced the same results as long as the Tabs were
over the background control.

Here is the explanation:

When you create a TabStrip child, it is inserted in the current tab.

Apparently, after having increased the Count property, gb.qt shows the last 
tab, whereas gb.gtk stays on the first tab. So when you browse the children of 
the first tab and insert a new TextArea, it is inserted there, and then you 
have one more child in the first tab. That new child is found in the next 
iteration of the browse loop, and so a new child is created again in the first 
tab, and so on, until no more control can be created.

I fixed the bug in revision #3154.

Subject: [Gambas-user] TableView issue
Message-ID: <AANLkTi=fPWCz6B2UMhXjGZ2zFwHwzuzRCw7W4UYaw_MA@...627...>

Hello List,

I found a strange behavior of the tableview control. I use Gambas 2.20, qt,
on ubuntu 10.04.

I try to create an editable table.
As long as I use only text input, it works fine.
As long as I use lists or text and list but with unprotected
(readonly=false, as by default) lists, it works fine. In this case I can use
the arrows to move up and down, left and right. It is very comfortable.
As long as I use protected lists (readonly=true) it works fine as well,
except that I cannot move left and right with the arrows. It is less
comfortable but still okay.

The problem comes when I use some columns with protected and some others
with unprotected lists.
In this case, when I use the arrows for moving horizontally and I move from
an unprotected cell to a protected one, it crashes the code with an error
message about the combo box.

If I was not clear then take the attached code, select a cell and move by
pressing the arrows. The middle column is "unprotected".


Can someone tell me if it's a bug or what should I do different?

Thx,
Robi

Any idea's how to do this.

I updated the svn today and since then some major parts of my code won't work, 
though the logic in those files has not been touched for months.

Any help appreciated
1) How to identify current svn version
2) How to select an arbitary version and roll back.

'svn info https://gambas.svn.sourceforge.net/svnroot/gambas/gambas/trunk' will 
give you information on the gambas repository.

'svn info' will give you information about the current directory.

Note that there is no "current version" of your local repository, as each 
directory and each file can come from a different repository version.

> 2) How to select an arbitary version and roll back.

'svn update -r REVISION'

Note that you may have conflicts, as with 'svn update'.

If you want to come from a fresh repository, you can do a checkout too by 
specifying the revision number.

'svn help COMMAND' can be useful too.

This was a bug! Can you try the revision #3162 to tell me if it works better 
for you?

That is a bug, but I thought I have fixed it. I must check again then...

Subject: [Gambas-user] Controls by code are invisible in Gnome
Message-ID: <AANLkTi=PCCDqtCCjKd850H_QHK4_2x_bJqiDrcpn7iNi@...627...>

I was testing a custom control in a Ubuntu 9.10 virtualized by
VirtualBox (using Gambas 2.18), and my controls become invisible in
execution time. This not happens on Kubuntu 10.04 on virtualbox too
(using Gambas 2.20).

I was suprized when I verified that the same happens with controls
provided by Gambas,  What's could be happening?

'lbl1 is invisible in time execution
PUBLIC SUB _new()
  DIM lbl1 AS NEW Label(ME)

  lbl1.Text = "Hi people"
END
