Message-ID: Benoit: Related with my last message about a Dirview problem (can't create a Folder when the folder's list its too big for be shown in screen and the "New Folder" line isn't visible), I've found a solution... but I don't know if it's a bug or just a bad use of class by my side. I've downloaded the DirView Class code from Gambasdoc and -after comment the Inherits UserControl Line- I've modified the NewFolder sub: Public Sub NewFolder() Dim sDir As String Dim sPath As String Dim iInd As Integer Dim clave As String sDir = ("New Folder") clave = $hTreeView.Current.Key iInd = 1 Do If Not Exist(clave &/ sDir) Then Break Inc iInd sDir = ("New Folder") & " (" & CStr(iInd) & ")" Loop sPath = clave &/ sDir Mkdir sPath AddDir(clave, sDir) $bDeleteOnCancel = True $bInRename = True ' 'The next two lines are mine $hTreeView[sPath].EnsureVisible Wait 0.01 $hTreeView[sPath].Rename Catch Message.Error(("Cannot create directory.") & "\n\n" & Error.Text) End Now it works as I expected -The new Folder is created even it's row isn't visible-. BUT I don't know if this modification is "correct" or interferes in some other behaviour of the class... Can you give some feedback about this topic? Regards From nigelverity at ...67...

(Nigel Verity) Date: Tue, 1 Apr 2014 14:21:18 +0100 Subject: [Gambas-user] DataControl Validation Message-ID: Hi I have posted a couple of questions recently on using the data-bound controls. My long-term aim is to design some template applications, combining Gambas3 with Sqlite, to fill the role of MS Access on Linux for creating "quick and simple" databases. LibreOffice Base is such a poor tool for developing database applications, I am convinced that Gambas provides a much more effective platform. The .validate() procedure on the datacontrol enables values to be tested and modified before saving. If the validation rules require that the record save be abandoned, this is achieved very simply using the STOP EVENT statement. However, this causes the display of a message box showing "Invalid value". Is it possible to suppress this message box or to modify its text? I am using 3.1.1 on Debian.

There are actually at least three ways to force recompilation: (1) Go to IDE and hit the "Compile all" button (2) Open a terminal, cd into your project's directory and do $ gbc3 -a (3) Open a terminal, cd into your project's directory and do $ rm -rf .gambas (in there are the compiled classes) and then try to run the project from the IDE normally.

I've been studying Gambas for almost a week and a half and I'm very impressed with the simplicity and elegance of Gambas' object oriented Basic language implementation. Congratulations to all developers, specially Beno?t Minisini. What a superb software development environment you've shared with us! I hope I can join you soon to work on its development. In the mean time, I'd like to kindly ask for some clarifications regarding the treatment of classes by the interpreter. Let 'MMain' be the main module of a Gambas program and the meta-syntactic variables 'CLASS-CLASS' and 'OBJECT-CLASS' be the expressions 'MMain' and 'Class.Load("MMain")' respectivelly. Consider the evaluation of the following expressions inside the 'Main' method of 'MMain' module: TypeOf(CLASS-CLASS) ==> gb.Class TypeOf(OBJECT-CLASS) ==> gb.Object As you can see the CLASS-CLASS expression yields a class, while OBJECT-CLASS expression yields an object. One might wonder what's the class of the latter: OBJECT-CLASS Is Class ==> True That's expected as we may presume OBJECT-CLASS evaluates to an object, of the class 'Class', which describes the class 'MMain', which in its turn is the result of the evaluation of CLASS-CLASS. Surprisingly enough, when one applies the same expression to CLASS-CLASS they obtain: CLASS-CLASS Is Class ==> True The only possible explanation is that CLASS-CLASS is simultaneously a class and an object. However, it doesn't behave as an usual instance of the class 'Class'. For instance, it is impossible to access the public methods and properties defined within the class 'Class' using some expression like 'CLASS-CLASS.SYMBOL' where the meta-syntactic variable 'SYMBOL' is a public symbol of the class 'Class'. Therefore, the assertion that CLASS-CLASS evaluates to some object which is an instance of the class 'Class' is somewhat meaningless underneath the usual concept of class/instance of object oriented programming. My first question is: why does Gambas behave this way? What's the reasoning backing up the exception to the general rule that the evaluation of 'CLASS-CLASS', while an instance of the class 'Class', represents? Would not it be simpler and more intuitive (hopefully without loss of technical merits) to take CLASS-CLASS as just a "pure" class? I came to this issue while writing a method for validation of function signatures in a component I'm working on. It works well with methods residing in dynamic classes, since given an object 'OBJECT' which is an instance of a dynamic class 'CLASS' which implements the method 'METHOD', one can easily obtain the method's signature with the expression 'Object.Class(OBJECT)["METHOD"].Signature'. However, for static classes I couldn't find a way to obtain the signature directly from the class object given that 'Object.Class(CLASS)["METHOD"].Signature' wouldn't work since 'Object.Class(CLASS)' evaluates to the class 'Class' and not 'CLASS' as would be desired, and we couldn't use it directly as in the expression 'CLASS["METHOD"].Signature' as one would naturally expect after pondering about the fact, pointed out above, that 'CLASS Is Class' yields 'True'. The only way I have succeeded to obtain the signature is using the name 'NAME' of the static class 'CLASS' within the expression 'Class.Load("NAME")["METHOD"].Signature'. That is unfortunate because I'm compelled to discriminate between static and dynamic classes, not to mention I need to find a way to obtain the name of a static class from itself. I thought there could be a more elegant solution. Is there? The ideal solution would be to provide a general way to get the "true" object of the class 'Class' which describes the class 'CLASS', since the fact that 'CLASS' is a "false" (and bastard) object of the class 'Class', and therefore doesn't describe its own properties while a Class --- but the properties of its objects --- is immaterial to any practical application I could think of. Summarizing: currently it seems only to be possible to obtain an object of the class 'Class' which describes the class 'CLASS' if you have an object which is an instance of it; therefore it only works for dynamic classes, and you have the burden of instantiation. Maybe I haven't looked into the right place. Could you, please, help me? Related to this issue is the problem of having a variable callback function as a property of some object from a given class. What do you think is the best way to setup a callback function for a method? Just to make it less abstract: I'm writing a component for plotting arbitrary numeric functions. The class 'Plot' implements all the plot logic, but it must callback a function, defined by the parent which instantiates it, to calculate the plot points. What's the best way to implement this behavior? I've tried defining an event for 'Plot' class so each time the 'Plot' object would need to (re)calculate the points, let's say for a change in the intended interval of the function's domain, the event would be raised, so the parent would have to be observing the 'Plot' object to intercept the raised event and then do the calculation. The problem is that by design the event handlers don't return values to the offending object, so the event handler at hand would have to make sure of returning it in some other pre-established manner, like storing the computed point in 'Last.Y', and there would be no check from the interpreter about the implementation following the function's signature and returning a 'Float' value, for example. So, I decided instead to store the object and method's name that implements the mathematical function into the Plot object, so it could call it for the computation of points and invariably receive a return value. But for that to work correctly I needed to check the function's signature. That's why I ultimately came to the issues presented above. One initial hope I had was that 'Function' were a native type of Gambas, as suggested by the expression evaluation 'TypeOf(FUNCTION) ==> gb.Function', where FUNCTION is the meta-syntactic variable for a function symbol in the current scope. Unfortunately, that turned out to not be true. Is there any reason to not make functions first-class citizens? That would solve my entire problem from the root, albeit the considerations given above are somewhat unrelated and should be considered anyway. Do you suggest a fourth way of implementing the callback function? Is there a standard or ad-hoc way I'm missing? Thank you in advance. -- ,= ,-_-. =.

I think you mean they aren't dynamic classes. Modules are static classes by definition, aren't they? Anyway, the reasoning until the paragraph you quoted above is independent of that attribute of classes; I mean, regardless of 'CLASS-CLASS' being static or dynamic every expression described until that paragraph works the same way. In the text I wrote, the differences between dynamic and static classes only show up in the process of obtaining a proper object of the class 'Class' which describes the given class 'CLASS-CLASS', what is perfectly possible for dynamic classes, but I fail to see how to accomplish the same with static classes without the knowledge of its name at compilation time. > I will look more closely later.

With you so far. But, as Jussi pointed out, we aren't talking about classes in general but - and that may be related to the problem following - about a Module which is a static class. And it is not at all for granted that they behave similarly. We can also have a singleton (Create Static) class which is to be classified as a dynamic class but behaves like an object most of the time you use the class name. > Surprisingly > enough, when one applies the same expression to CLASS-CLASS they > obtain: > > CLASS-CLASS Is Class ==> True > > The only possible explanation is that CLASS-CLASS is simultaneously a > class and an object.

Besides the normal class/object model where a Class class would only be used for reflection, we want to, like, access class constants from the class name, like Align.Center in the Align class. That would be impossible if the symbol "Align" referred to an object of the Class class because it then wouldn't have the possibility to exhibit its own symbols. On the other hand, it _is_ a class and that's why TypeOf() is right. Basta. :-) > I came to this issue while writing a method for validation of function > signatures in a component I'm working on.

It seems that TypeOf(CLASS) served you well with MMain. It may not be an instance of the Class class but you can cast it to one :-) I attach you a project that, in its heart, uses the following procedure to print the signature of the first found method in some object's class: --8<------------------------------------------------------------------------ Public Sub PrintFirstMethod(hObj As Object) Dim hClass As Class Dim sSym As String ' Static class? Try hClass = hObj ' Not a static class, then we can use Object.Class If Error Then hClass = Object.Class(hObj) For Each sSym In hClass.Symbols If hClass[sSym].Kind <> Class.Method Then Continue Print "Signature of";; sSym;; "in";; hClass.Name; ":";; hClass[sSym].Signature Return Next Print "No method found in";; hClass.Name End --8<------------------------------------------------------------------------ It first tries to cast the given object to a Class object which will succeed if you give a static class, like in PrintFirstMethod(MMain), and will fail else. If it fails, we can be sure that it is a real object and can use the Object class. > Related to this issue is the problem of having a variable callback > function as a property of some object from a given class.

In Gambas, you mostly do it the other way around. If your Plot object wants data, it would raise its Plot_Data event which needs to be intercepted by your code. Then you would fill a property of the *Plot* object, like Plot.Data which you can decide to be a Float or whatever. You can see this strategy being used rather successfully in the interplay of Editor and Highlight of gb.qt4.ext or in DataBrowser of gb.db.form and others. > So, I decided instead to store the object and method's name > that implements the mathematical function into the Plot object, so it > could call it for the computation of points and invariably receive a > return value.

I don't know why, maybe because there are better alternatives, or functions - which are actually methods - don't act very object-like (they have no methods themselves or data you could manipulate [ hmm, actually they have a signature... but there are better ways to do what you want ]). You need to have an object that just *resembles* a function but isn't simply an array of bytecode. > Do you suggest a fourth way of implementing the callback function? Is > there a standard or ad-hoc way I'm missing? > There is the way I described above, there is the Eval() function which _may_ suffice for your needs and there is another possibility: define your interfaces. If your Plot object has a plottee (how I call the object providing plot data), require that the plottee exhibits a specific interface which the interpreter can check. It works like this: 1) Create a non-creatable Plottee.class and define a method to access points for the plot from it. This is the base class for all things that can deliver plot data. 2) In your Plotter.class, request a Plottee object as an argument to get your points. Consequently, your user has to define their own Plottee-like class to interface with your Plotter logic, by inheriting the Plottee.class. The interpreter will check if they inherits correctly (which includes overriding methods and properties with the correct signature). Attached is a project that shows this. If you, e.g., declare _next() in EvalPlottee as returning an Integer or anything not PointF, the interpreter will raise a runtime error. There may also be some things you didn't know yet. Feel free to ask. This may not be best way. Actually, I find it myself way too Java-like but I'm hungry and this mail stands between me and dinner. You should also consider the event-based approach outlined above which is more like how things are done in Gambas.

As you have shown that'd be impractical. After all we have the class 'Class' to derive objects that grants type introspection capabilities, the way it ought to be. I'm just very concerned about the 'Is' operator which says that every class is somehow an object which is an instance of the class 'Class'. That seems to me rather inconsistent. Notice that 'TypeOf' is a consistent function as far as I'm aware of: it says that classes are classes and objects are objects. In fact, I share with you the opinion that it's the authoritative reference about such matters. ;-) Now, having a class named "Class" that is in fact intended for introspection is a bit confusing for newcomers but it's not inconsistent at all. Maybe it should be called 'ClassIntrospection' or something to avoid that. I think what we can't do is to assert that every class is an instance of the class 'ClassIntrospection', because it's clearly not the case, regardless of what the operator 'Is' thinks; either it knows something about inheritance that I do not or it has a lot to learn with its cousin 'TypeOf'. I can't help but ask: am I missing some metaphysical principle about the way classes are arranged? Am I, 'Is'? ;-) Anyway we do need classes as first-class citizens of Gambas, but we can't use the name 'Class' for it until we change its meaning as described above. The root of all evil seems to be that the expression 'Dim hClass As Class' makes 'hClass' a handler for introspection objects of the class 'Class', while it actually should be making a handler for pure classes, as 'MMain', for example. I think it'd be far more intuitive, and perhaps yet more useful. If one wants an introspection object, they could declare it as 'Dim hObject As ClassIntrospection'. Good or not, one consequence of that is that it would be possible to make multiple aliases for a single class. But what's the problem? Isn't this the current situation for a single object? > > I came to this issue while writing a method for validation of > > function signatures in a component I'm working on. > > Pretty strange but sure a good way to learn Gambas primitives if you > can deal with it :-) And your first component after a week and half. > An impressive learning curve!

I've looked into language statements, native functions, operators and classes and have found nothing. It just happened to be the wrong place: all the magic is in a simple casting; a somewhat unpredictable one, though. Casting is really a subject matter that seems to be almost entirely overlooked in the language documentation. I couldn't find anything specifically about it at Gambas' Wiki. Is it even an official language feature? The only meaningful casting I did know about were those involving different numeric types, including booleans. Interesting enough, I've found that casting classes to objects results in introspection objects for the original classes, so you don't have to specifically cast them to the class 'Class'. That's a really meaningful and useful behavior. Take a look: Dim hObject As Object = MMain TypeOf(MMain) ==> gb.Class TypeOf(hObject) ==> gb.Object hObject Is Class ==> True hObject.Name ==> "MMain" It means that classes are already casted to introspection objects of the class 'Class' when your function starts. > > Related to this issue is the problem of having a variable callback > > function as a property of some object from a given class.

The idea you described above was my first implementation. Thinking better now, it's actually a good method. The flaw I saw within it is not a real concern; it was just a (perhaps silly) matter of style. Indeed the 'Eval' function will be of opportune use when I start to think about functions only known at runtime. Define my own interfaces?

My current implementation does kind of that, I mean, it defines a Plottee class, which the Plotter class uses for retrieving the points. However I was struggling with how to make the Plottee class instantiate objects which could use arbitrary functions. So I've resorted to implement it in an obscure way referencing objects and methods by its name and checking its signatures. As you have shown it turns out to not be necessary at all. Notwithstanding, it was very useful to learn about the guts of class treatment; the issue which originated this correspondence. :-) There is only a down side of this interface method: every new function needs a entire new class to implement it. Furthermore it's only useful for functions known at compilation time. > There may also be some things you didn't know yet. Feel free to ask. Thanks, I took note of that.

Yeah, perhaps the initial event-driven interface is actually the best one. Thank you so much for the enlightening response and source code examples. Happy Hacking!

All that is because, "is a" has two meanings in Gambas. 1) An object reference A "is a" class B. It means that the class of the object A is the class B. 2) An expression "is a" datatype. And there are two datatypes, "gb.Object" and "gb.Class". "gb.Object" is any expression that returns a non-null object reference. An object reference internally includes two pointers: a class pointer, and an object data pointer. "gb.Class" is any expression that returns a class. It includes one pointer, the class pointer. "gb.Class" exists only for internal optimization reasons. I could have used instead a "gb.Object", with a null object data pointer. But it would have been slower. Now, as stated in the wiki, classes are really objects whose class is the "Class" class. But a reference to a class as an object is not the same thing as a reference to the class. The first one has methods that describe the class structure, the second one allows to call the static methods of the class. > > I came to this issue while writing a method for validation of function > signatures in a component I'm working on.

(Internally, the function datatype exists, but all non-official things do no exist. By the way I told you nothing). When I need doing these sorts of things, I'm only using dynamic object. And if I have a static class, I transform it into a auto-instanciable dynamic class (like Forms objects, for example). If a class is auto-instanciable, using the class name as an object automatically transforms the "gb.Class" expression into a reference to the auto-created internal singleton object. So you exactly have the syntax you need. And when I will succeed in implementing a clean global syntax, you will just have to transform your auto-creatable class back to a static class.

A simpler example of its use is the ImageView control located in 'gb.form'. You use the ScrollArea exactly like the DrawingArea, except that: 1) You must define the contents size with the ResizeContents() method. 2) You must take the vaue of ScrollX and ScrollY properties into account when drawing inside the Draw event handler (at least for things that must move with the scrollbars). 3) A ScrollArea has no "Cached" property. You must implement the Draw event handler. 4) You have a "Shadow" property if you want to draw nice shadows on borders where scrolling is possible.

But I can't quite understand how have you reached the conclusion that "classes are really objects whose class is the 'Class' class"? What is the criteria classes are satisfying that 1) Makes them objects. 2) Granted (1), makes them instances of the class "Class". Are the answers to these two questions consistent with the Gambas' meaning of "object", "class" and "instance"? Or is that just a particular exception to the general rule? Do you see any problem with the perhaps more intuitive and consistent approach of making 'Class' a primitive type as explained in the model below? ** Reformulation of the interpreter's behavior regarding classes ** The declaration Dim hClass As Class = MMain would make 'hClass' point to the same class that 'MMain' points to so that TypeOf(MMain) ==> gb.Class TypeOf(hClass) ==> gb.Class If(hClass = MMain, "Equal", "Not Equal") ==> "Equal" MMain Is Class ==> [Error: Unexpected Class] hClass Is Class ==> [Error: Unexpected Class] The errors are the same current raised by the expression MMain Is Integer ==> [Error: Expected Integer] This is consistent because like the type 'Integer', the type 'Class' would be not a class, and therefore would not make sense as the right-hand side operand of the 'Is' operator which is intended to check instantiation regarding inheritance, which is clearly not applicable to classes in the reformulated model. On the other hand to obtain the introspection capabilities the declaration Dim hClassIntrospection As ClassInstropection = MMain would make 'hClassIntrospection' points to the object which describes the class 'MMain' so that TypeOf(hClassIntrospection) ==> gb.Object hClassIntrospection Is ClassIntrospection ==> True MMain Is ClassIntrospection ==> False hClass Is ClassIntrospection ==> False hClassIntrospection.Name ==> "MMain" If(hClassIntrospection = MMain, "Equal", "Not Equal") ==> [Error: Type mismatch: wanted Object, got Class Instead] If(hClassIntrospection = hClass, "Equal", "Not Equal") ==> [Error: Type mismatch: wanted Object, got Class Instead] Casting of classes to objects as in the declaration, Dim hObject As Object = MMain would retain the useful behavior of resulting in introspection objects: hObject Is ClassIntrospection ==> True I think this reformulation of the model would avoid the apparent ambiguity and the exceptional status of classes as objects while aiding consistency and maintaining introspection features.

For a given class named 'CLASS' the expression 'CLASS Is Class' evaluates to 'True' not because 'CLASS' is an instance of the class 'Class', but because in a object context 'CLASS' gets cast to its introspection object which in its turn is an instance of the class 'Class'. It's so obvious and clear now! The interpreter's behavior is perfectly consistent and unambiguous with respect to this matter. I feel I owe you and the operator 'Is' an apology, as I've suggested the interpreter's behavior was somewhat inconsistent. Sorry. In the end it's very good that this has happened. Now this subject is solved once and for all, and available in the mailing list for posterity. That said, I still would love to have a "pure" class type. It'd be like 'Class' or 'Object' but it wouldn't cast classes from 'gb.Class' to 'gb.Object'. That way we could store classes inside variables, make them accessible under properties and pass them as arguments to methods. Something like: Dim hPureClass As PureClass = MMain TypeOf(MMain) ==> gb.Class If(hPureClass = Identity(MMain), "Equal", "Not Equal") ==> "Equal" Public Sub Identity(hPureClass As PureClass) TypeOf(hPureClass) ==> gb.Class Return hPureClass End As far as I can see, it would not disrupt any existing code and would add a feature to the language that allows some things that are not strictly possible now, for example the implementation of callback functions by anonymous references to static or dynamic classes. However, if you happen to think that although being backward compatible this change would be too big or not worthy, it'd be sufficient, although not optimal (or so convenient as it could be), to circumvent the current limitations by being able to (un)cast an introspection 'Class' object to the class it describes, perhaps by a method or property thereof, intended for immediate use (a little bit like virtual classes). So it'd look like: Dim hClass As Class = MMain TypeOf(hClass) ==> gb.Object TypeOf(hClass.Class) ==> gb.Class If(hClass.Class = MMain, "Equal", "Not Equal") ==> "Equal" I don't know if it's possible at all given the current implementation of the interpreter. In the case it happens to be possible and relatively easy to implement, it'd solve the biggest drawback presented in this correspondence. Thank you for your attention and interest.

For Counter1 = 0 To 32766 If Exist(BasePath & "/image/pwo/" & Counter1 & "_0.png") Then ' Load the texture. ' Code commented out for brevity. Endif Next executed fairly quickly. I tested the bare loop by removing any code executedif Exist returned True, and the loop is slower than it used to be when actually loading textures. Unless the underlying packages in [K]ubuntu (13.10) or my network are causing the problem (the file checks are performed over an NFS share on my file server), there is a massive increase in the overhead of the Exist function with respect to files on a network share. The empty loop over NFS takes 43 seconds. Performed locally on my workstation's SSD it takes 0.04 seconds. Were any changes made to Gambas that could have caused this, or should I start investigating my file server and/or network's performance? Copying a file from my server to my workstation transfers at 120 MiB/s, which is extremely fast. The Exist function checks transfer at 500 KiB/s.

(Bruno =?UTF-8?B?RsOpbGl4?= Rezende Ribeiro) Date: Mon, 14 Apr 2014 22:56:05 -0300 Subject: [Gambas-user] Advising methods of non-fixed argument tuple in a parent class Message-ID: <20140414225605.1f499874@...3316...> Hello all! Suppose we want an array of variants which has the nice property of raising an event after any modification, like addition or removal of elements, has occurred to itself. Since the class 'Variant[]' does not have this specific capability but, on the order hand, has every other desired array handling functionality we need, we'll make good use of the OOP philosophy of re-usability and extend it to add our desired functionality. Our extended class will be called 'VariantArray' and will have an event called "Update" that will be raised after any modification procedure has taken place. Therefore, in its header we so declare: Inherits Variant[] Event Update() We now need to advise[1] the parent's methods intended for modification of the array structure. The idea is rather simple: we supplement a parent's method definition by simply raising the 'Update' event after its completion. Let's use the special method '_put' as our example case. This method allows instances of our class to be used as arrays in assignments. In a hypothetical N-dimensional array we'd have the following signature: Public Sub _put(vVariant As Variant, iIndex1 As Integer, ..., iIndexN As Integer) Where '...' is a meta-syntactical symbol which represents the full list of indexes parameters varying from 2 to N-1. Thus the override function would be: Public Sub _put(vVariant As Variant, iIndex1 As Integer, ..., iIndexN As Integer) Super._put(vVariant, iIndex1, ..., iIndexN) Raise Update() End For an array of non-fixed size we'd have the following signature: Public Sub _put(vVariant As Variant, iIndex1 As Integer, ...) Where the syntactical symbol '...' means the method can take extra arguments. As the result of the definition of an arbitrary argument tuple there is no way the previous syntax for calling the parent's method definition could possibly work, i.e., in the expression Super._put(vVariant, iIndex1, ...) there is no string of syntactical symbols one could replace the meta-syntactical symbol '...' in order to make the parent's '_put' method receive the same argument tuple of the child '_put' method. The only hope to solve this problem is to use the static class 'Param' to access the extra arguments in the form of an array. However, we can't use an ordinary function call to accomplish what we want, because it won't accept an array as a meta-argument. Fortunately that's what the method 'Call' of the 'Object' class provides us. Therefore, being 'PARENT' the meta-syntactical variable whose hypothetical syntactic expression points to the parent's method implementations, we'd use: Object.Call(PARENT, "_put", [vVariant, iIndex1].Insert(Param.All)) Even so, there is no expression one could fit in 'PARENT' that would make the call work as intended. In the previous case of an arbitrary but defined number of arguments we used the 'Super' keyword to reference the parent's method implementation. This worked there because it was a direct and imediate use, and would not work here in place of 'PARENT'. So we are stuck, because to reference the parent's method implementation we need to use a syntax which doesn't allow the use of a non-fixed tuple of arguments, and in order to use a non-fixed tuple of arguments we have to give up our ability of referencing the parent's method implementation. The conclusion is quite clear: it can't be done. My questions are: is there any error with the reasoning given above? If not, is there a workaround? If not, how could we improve Gambas to solve this problem? Irrespective to all of this, do you suggest another approach to accomplish the initial objective of obtaining an array which raises events when modified? What about the general idea of advising methods of an inherited class? In general, how can we make it work? Thank you for your attention. I look forward to your answer. Footnotes: [1] I've borrowed the term "advice" from the GNU Emacs terminology for a very similar concept.

AFAIK, you are right that we cannot call Super._put() directly when we want to pass a variable number of arguments. For that, we need to manipulate the Gambas stack to push that stuff and then call the method. That's precisely when Object.Call() would come into play and AFAIK, you are right, too, in that we cannot use Super there as it cannot be used alone. And there is no other way of accessing our inherited class. That looks like a limitation. However, multi-dimensional arrays are limited to eight dimensions in Gambas, so there is no practical problem at present that would you keep you from Select-Case'ing Param.Count and doing Super[cased-arg-list-here] = vValue. But I believe in the existence of problems of bigger importance than practical problems, like ideational ones [ hope that's the right English word... ] where the above solution fails miserably. In the Tobias-Boegian school of Gambas, we distinguish between "real" multi- dimensional arrays and "derived" multi-dimensional arrays. Real m-d arrays are those you were about to use, the ones you declare with Variant[iDim1, iDim2, ..., iDimN] where N <= 8. These have at least three drawbacks: (1) their number of dimensions is limited by 8; (2) the size of each dimension is static; and (3) they can only shape like matrices. Derived m-d arrays are array classes built by the interpreter out of other classes. If you have a class x, then x[] denotes an array type containing elements of type x. Moreover, x[] is again a class. So if you repeat that process, you obtain x[][] which is an array class that can hold x[] objects. Let's look at the three above points. It turns out that derived m-d arrays are superior: (1) no limit; (2) sizes of dimensions are fully dynamic; and (3) we are not limited to matrix-shape. Maybe now it becomes clear what I meant with matrix-shaped: if you have real m-d arrays, any dimension must have the same size at every point, e.g. if you have a m-d array of three dimensions, it will always look like a cuboid. Whereas 3d derived m-d arrays are arrays of arrays of arrays and every two arrays in that system may have different sizes. [ I first posted that explanation here[0]. ] If you are willing to use derived arrays (there seems no reason against), you don't have that problem of variable argument lists, as there is no syntactic multi-dimensional-ity, you just happen to access 1d arrays whose elements are again arrays. And finally let me tell you something about extending classes: it gets especially cool when you call your extending class like the extended class. Above, you would not call your class VariantArray but Variant[]. [ At present, you have to create .src/Variant[].class outside of the IDE in your project because the IDE forbids use of brackets in class names. However, the interpreter doesn't seem to have any problems with that. ] That way, you are overriding the Variant[] class in the interpreter's global symbol table, using inheritance, i.e. you extend it. You can add features to Variant[] which are immediately available to all users of the Variant[] class without having to change any code. That's explained in the docs as well[1].

Yup. You got that perfectly right! ;-) I wonder if using your summarizing sentence right away from the beginning of my original text would have had the same effect. In affirmative case I'm being overly verbose, but it happens that I'm not the biggest fan of misunderstanding, so I'd rather prefer to play a little bit safer. :-P Nevertheless, it'd be pointless if actually the extensive explanation achieves the contrary effect: hard comprehension. I welcome feedback on this matter too. > AFAIK, you are right that we cannot call Super._put() directly when > we want to pass a variable number of arguments.

So, I guess it'd be a reasonable feature request to include at least a way to bypass this particular limitation.

Oh... I just forgot for a moment that hard-coded limitation of 8 dimensions. But yeah, given that our concerns are attached to practical situations you've suggested a perfectly acceptable solution, unfortunately somewhat inconvenient, though; yet as convenient as it could possibly be with the current interpreter. > But I believe in the existence of problems of bigger importance than > practical problems, like ideational ones [ hope that's the right > English word... ] where the above solution fails miserably.

[ I first posted that explanation here[0]. ] I guess [0] is in German, and thus unfortunately I can't read it. I have the feeling, though I could be deadly wrong, that outside this mailing list, there are a lot more information and discussion about Gambas in languages other than English. It seems that [1] supports this claim. It's unfortunate because fewer people can have access to that information, and it segregates the user-base to some extent. > If you are willing to use derived arrays (there seems no reason > against), you don't have that problem of variable argument lists, as > there is no syntactic multi-dimensional-ity, you just happen to > access 1d arrays whose elements are again arrays. I agree with you that the use of m-d derived arrays is entirely taken care of by the interpreter and it's quite transparent to my code. However, if I'm going to replace the class 'Variant[]' presupposing full backward compatibility, as you've suggested below, I must make sure my code properly handle "real" arrays as well. > And finally let me tell you something about extending classes: it gets > especially cool when you call your extending class like the extended > class.

If the behavior of having classes with brackets in their names is useful --- and even the interpreter is fine with that --- I don't see why this wouldn't be an IDE bug. Have you or anyone else addressed this bug or submitted a bug report on this? > That way, you are overriding the Variant[] class in the interpreter's > global symbol table, using inheritance, i.e. you extend it.

Talking about that, don't you think that an 'Update' event as I've described would be a very nice core addition to the 'Array' class in the main distribution? It seems to me it would be generally useful for users. Poor 'Array' class... it doesn't have any events --- let's give it some useful ones. ;-) I really appreciate your very interesting response.

Suppose we are overriding the class 'Array' to add the event 'Update' which will be raised after the completion of any method which could possibly modify the array structure. We start by the 'Remove' method which has the following signature: Public Sub Remove(iIndex As Integer, Optional iLength As Integer) As our override method is not much more than a wrapper around the parent's method, it needs to call 'Super.Remove' method with the same arguments it has received in the first place. Consider our first attempt to do just that, which would be: Super.Remove(iIndex, iLength) However, that call won't work as expected because although 'iLength' is received as an optional argument, it's invariably passed along to the parent's method, be it originally given or not, in which case it would default to '0'. In order to solve that problem we may consider to discriminate semantically the optional argument, if that is at all possible. To discover if that is actually the case, we must prove that either one of the following properties must hold about the semantics of the method for some possible default value of the optional argument: 1. The method's semantics is defined for the default value of the optional argument, but would be indistinguishable if the optional argument were otherwise omitted. 2. The method's semantics is undefined for the default value of the optional argument. It turns out in this particular case the 'Remove' method satisfies both properties. For the first property we can just take 'iLength' as '1', since the default behavior (when iLength is omitted) is to remove just one element of the array. Then, our method would look like: Public Sub Remove(iIndex As Integer, Optional iLength As Integer = 1) Super.Remove(iIndex, iLength) Raise Update() End For the second property we could take 'iLength' as '0' because there is no a-priori nor auto-evident distinction between removing zero elements of an array and not executing the procedure of removal at all. Therefore we can be assured that no one would expect a meaningful behavior from a non-meaningful argument and then reserve that for internal use, promoting the semantics of the method as undefined/unpredictable for that particular optional argument's default value. Our override method would be: Public Sub Remove(iIndex As Integer, Optional iLength As Integer = 0) If iLength = 0 Then Super.Remove(iIndex) Else Super.Remove(iIndex, iLength) EndIf Raise Update() End Notice that this latter method's form could be used to obtain a method functionally indistinguishable from the former method's form by just replacing the zeros by ones. Nevertheless, the converse is not true. Although, we could successfully solve the problem for this particular instance of the problem resorting to semantical analysis, it does not help much with other methods which have an entire different semantics whose analysis must always be done in a case-by-case basis. Even worse, it's possible to prove the following statement: There is a primitive method, which accepts optional arguments, that can't be perfectly wrapped by any non-primitive method of the same signature if, and only if, there is a way for primitive methods to unambiguously check whether a particular optional argument was supplied and there is no way of doing so for non-primitive methods. Where 'primitive method' is defined as a method not written in Gambas which is callable from at least one method written in Gambas; and 'non-primitive method' is defined as a method written in Gambas. Furthermore we admit the premise that it's impossible for a non-primitive method to call another method referencing the unchanged original argument tuple. The theorem makes explicit our necessity of providing a way of checking unambiguously, in Gambas code, whether any given optional argument were actually supplied or, alternatively, preventing primitive methods of doing so. Otherwise, there will be methods for which it is impossible to remedy the situation of perfect-wrapping by pure semantic analysis. Now for a more pragmatic approach, it'd be very useful to document the default value of optional arguments as part of the method's signature for all primitive and non-primitive methods where it is applicable. Those methods can always be perfectly wrapped using the first property of the semantical analysis given above. Moreover there is a trivial algorithm to do so, granted we know the default values of every optional argument. That way we eliminate the step of semantical analysis even without modification to the interpreter's code. My questions are: do you see any problem with the reasoning outlined above? Have you ever faced the same problem? Do you know some workaround? How do you think Gambas may be improved to solve this problem? Thank you. -- ,= ,-_-. =.

We were only interested in Variant[] when we worked out that solution (our goal was to make homogeneous (all elements have the same type) Variant[] sortable as if it was a specialised native array of that type), so that problem didn't emerge. If my understanding is right (s. gbx_class.c), the behaviour makes sense as follows: native array classes are included explicitely in the interpreter, but non-native arrays are derived on-the-fly at runtime. So, if you create a NativeDatatype[].class, you override that included class, as you have seen, and everything is OK. If you create MyClass[].class, this will actually be the original class, as there is no MyClass[] in the interpreter's global symbol table yet. If you later reference MyClass[] somewhere in actual code, the interpreter will derive an array class from MyClass and override *your* class. That means that your class' logic is irretrievably lost for the interpreter (as his derived array classes will not call Super methods). This would explain what happens, but Benoit knows better.

I'm working on C/C++ components for Gambas (and if you write C/C++ components for Gambas, it is inevitable to look at the interpreter's source once in a while).

BUT there is only one German Gambas community I know of and that's the Gambas-Club of which I have taken care recently. Since I'm active on this list, the link is established (it's just not broadband). Of Ru Vuott and Willy Raets, I have noticed that they must have taken similar positions. I suppose that this is how it works with the other forums as well. So potentially, we can transfer most of the stuff into this list if people ask the right questions... maybe. :-) Too bad that you can't understand German, though. I had luck with others in the past who could at least somewhat read German. Actually, I have translated everything about array classes I said in that post in my last mail but there is also a German online book[0] we're writing about Gambas which happens to contain "original research" and "exclusive material" :-) (may it only be up-to-date documentation of some classes). > > > And finally let me tell you something about extending classes: it gets > > especially cool when you call your extending class like the extended > > class.

I myself never needed a data container which would tell me when it changed. That is also a decision I have made for gb.data: classes in there are data containers. They don't communicate with me (raise events), they only contain. And raising an event in code means to execute some functions, no matter if that object is actually able to generate events. It is not, e.g. when it has no event name which is the case for all current code. Since changing data in an array is surely one of its most used functions, it would be cool to see a benchmark with and without that event. But I bet the benchmark with event wouldn't look too nice...

Depending on how your set of functions is structured and how many you have of them, you could do one of at least two things: 1) Define a (Create Static) class that represents your function, implement the function in its _call() special method, and then you can pass that class (which is actually a singleton object) as a surrogate function pointer. [ There are other variants of that trick but this one is as close to the syntax of function pointers as I could get it. ] E.g. you want to pass a function pointer that just prints something, then you define your --8<--[ PrintFunction.class ]----------------------------------------- ' Gambas class file Create Static Public Sub _call(sMessage As String) Print sMessage End --8<------------------------------------------------------------------ and use it like PassAFunctionPointer(PrintFunction) where Public Sub PassAFunctionPointer(hFunc As Object) hFunc("wherever you get your arguments from") End 2) Define a (Create Static) class that represents your entire set of functions. That class implements functions of known names that you can later refer to: --8<--[ PrintFunctionSet.class ]-------------------------------------- ' Gambas class file Create Static Public Sub NormalPrint(sMessage As String) Print sMessage End Public Sub DecoratePrint(sMessage As String) Print "[*]";; sMessage End --8<------------------------------------------------------------------ You'd use this set like PassAFunctionSet(PrintFunctionSet, ["NormalPrint", "DecoratePrint", "DecoratePrint"]) i.e. you give the set and then a sequence of function names to be executed: Public Sub PassAFunctionSet(hSet As Object, aFuncs As String[]) Dim sFunc As String Dim iInd As Integer For Each sFunc In aFuncs Object.Call(hSet, sFunc, ["your argument #" & iInd]) Next End Of course, if you have lots of functions of similar purpose, you would opt for the second way because it means less classes and better organisation.

Suppose we are overriding the class 'Variant[]' to add the event 'Update' which will be raised after the completion of any method which could possibly modify the array structure. In particular, we need to override appropriately any function that happens to do so. For exposition purposes let's consider the 'Extract' function, which removes one or more elements from the array and returns them. It's signature is as follow: Public Function Extract(iStart As Integer, \ Optional iLength As Integer) As Variant[] Our inherited class has, hence, to override this function with another of the exact same signature, by Gambas' rules. However, it doesn't make sense to return an object of the base class, while the operation is executed by a derived class over an object thereof. It seems there is no easy or natural way around it. We could declare a second extraction function for the derived class named after a different symbol like "ExtractDerived", but we'd break the interface, what isn't a desired outcome. Another approach would be to forget this particular base class and go upwards until there is no possible conflicting functions and to inherit from there, what happens to be in this case the immediate base class of 'Variant[]' called "Array". However, we'd have to re-implement large portions of the 'Variant[]' class, that could otherwise be immediately deployed if not by our particular design problem at hand. One last, and arguably more reasonable, approach is to give up the syntactical native language's feature of inheritance --- and its useful properties -- and to define a dedicated container base class, which inherits from nowhere, semantically wrapping all functionality of the class 'Variant[]'. It'd work as a layer for accessing the underlying variant array which would be stored in a private variable and isolated from the outside world, i.e., not directly accessible by any property. The only way to modify the array's content would be to use the class' interface which would mimic that of 'Variant[]'. As we've seen, there is no way if not by modifications of the interpreter's very core. Thus, I'd like to know why Gambas enforces the signature of functions onwards inherited classes. If not by technical reasons, but only for methodological consistency requirements, I'd like to suggest that we make it, at least, allows to use the inherited class in place of the parent class within method signatures. Personally, I'd find yet more useful if there were no restriction at all. A very interesting and useful feature, related but independent of this suggestion, is that the interpreter could take care of casting objects in both directions in an hierarchy of classes. In order to accomplish it, there would be introduced two special methods which would be implemented in any class the programmer deems them meaningful and useful: '_castUp' and '_castDown', for casting an object from the inherited to the parent class, and from the parent to the inherited class, respectively. Being 'ThisClass' the inherited class and 'UpClass' its parent, the special methods signatures would be: Static Public Function _castUp (hThisClass As ThisClass) As UpClass Static Public Function _castDown (hUpClass As UpClass) As ThisClass The job of the interpreter would be to call these functions, in a possible chain, to cast automatically upside or downside every time an object of certain class is used in a context that requires an object of another class but in the same hierarchy.

Dim hChild as CChild Dim hParent as CParent hChild= New CChild hParent = hChild However, there is a use for a generalised castDown method. We have quite a few situations when the exact "child-type" is unknown at the time the object is created, but we know that when the methods that create the object are complete then that specialisation will be resolved. Particularly this happens with single pass parsers where the specialisation can't be resolved until some subsequent line of data is parsed. (A specific example, in many of the auction lists we receive, line N can be recognised as a new horse by virtue of the fact that the line begins "Lot [1-9]* " but the fact that it is a yearling or a mare or whatever is not disclosed until we get to line N+2 or N+3), As far as I know, something along the lines of Dim hParent as CParent Dim hChild as CChild hParent = New CParent With hParent .set the property values as we know them initially End With ... hChild=hParent <-- This bit doesn't "work" hChild.someproperty = somenewdata Here is how we do it, (which goes in the most ancestral class of the chain) (and appears to have worked OK for ~3 years): '' Casts the current object as an instance of the **sNewClass** class. The ''`new class must be a descendant of the current class. Public Function Cast(sNewClass As String) As Object Dim hNew As Object Dim sSymbol As String hNew = Object.New(sNewClass) ' If morphing downwards, then the cast is allowed! If (Object.Is(hNew, Object.Type(Me))) Then Goto DO_CAST ' Check we are trying for a cast in the proper chain If Classes[sNewClass].Parent <> Object.Class(Me).Parent Then Error.Raise(Subst("Illegal cast: &1 --/--> &2", Object.Type(Me), Object.Type(hNew))) Endif DO_CAST: For Each sSymbol In Object.Class(Me).Symbols If sSymbol = "."

I'm surely not good as you are but I didn't understand the > meanning of castup or down... What is it for ? Let me give you an abstract example. Suppose we have the class 'SuperClass' which implements the function 'Frobnicate' that has the following signature: Static Public Function Frobnicate(hSuperClass As SuperClass) \ As SuperClass Suppose now that we've extended our original class, and thus derived the class 'SubClass', and let 'hSubClass' be any object thereof. Suppose the function 'Frobnicate' was not overridden and that 'SuperClass.Frobnicate(hSubClass)' is generally not that useful because the implicit identity casting doesn't generate a very meaningful 'SuperClass' object for the problem at hand. However, we have a much more interesting idea than the interpreter of how to map 'SubClass' objects to meaningful and useful 'SuperClass' objects. Here the proposed special method '_castUp' comes in hand. We add it to the code of 'SubClass' in order to do the desired up-cast automatically: Static Public Function _castUp(hSubClass As SubClass) As SuperClass ' Do a magical conversion using arbitrary processing in accordance ' with our idea of a canonical map from 'SubClass' to 'SuperClass'. End Now when the interpreter evaluates the expression 'SuperClass.Frobnicate(hSubClass)' it'll notice there is an up-cast method and then it'll give this precedence over the implicit identity casting. Now we have a meaningful object to work with! The '_castDown' special method works analogously but the other way around. The only major difference is that the interpreter doesn't have a standard implicit identity cast in this direction and therefore raises an error when one tries to use a 'SuperClass' object in a 'SubClass' context. The main point to emphasize here is that we are interested in non-trivial castings. Therefore, we need it both directions and identity casts (the copy of common properties) doesn't suffice. Hope it helps. Happy Hacking! -- ,= ,-_-. =.

I hacked the interpreter today - just to get a better idea of what is going on in this case - and my patched gbx3 now accepts that you substitute, e.g. VariantArray for Variant[] in the signature of VariantArray.Extract() (of course, VariantArray Inherits Variant[]). Generally, if you override a class' method or property, you can substitute any class farther up the inheritance hierarchy with the overriding class. Here is a slightly related post by Benoit about signature checks[0] but I don't know if the reasoning applies to inherited classes, too... but continue reading: After I got the signature accepted, there were type conversion problems when I tried to convert the return value of Super.Extract(), which is Variant[], as a VariantArray. I hacked that away too in the two possible ways: (1) When VariantArray = Variant[], leave the value be a Variant[] behind the scenes. This imposed the problem that a subsequent call to Extract() would use Variant[]'s version and thus make the object useless (e.g. no Update events anymore). (2) When VariantArray = Variant[], I told the type system that the Variant[] is legally a VariantArray and that made the interpreter segfault deep inside its gears (which was expected). So there must be some serious technical reason against that. But only Benoit can tell us the truth. We could circumvent that crash when we simply disallowed that conversion and had a method that would create a VariantArray from a Variant[], by copying elements. There is a _convert interface available for native classes (those written in C/C++) to convert an object into another one of a different class. That this is unavailable to Gambas programmers has obvious technical reasons. But the one _convert() implementation I looked at (in gb.clipper), did the same: it created a new object of the destination type and copied the relevant parts of itself into that new object.

Attached. But be warned (again?): the interpreter is actually not my business. Virtually, I don't even know what I've done to the code as an entire with my patch but it worked in the single test case I had. I tested code like this to have VariantArray implement Extract() and it succeeded: Public Sub Extract(Start As Integer, Optional Length As Integer = 1) As VariantArray Dim hNew As New VariantArray Dim vElt As Variant For Each vElt in Super.Extract(Start, Length) hNew.Add(vElt) Next Raise ExtractEvent Return hNew End Note that VariantArray.Extract(), just like Variant[].Extract(), returns a new object which has, by default, no event name. So don't be surprised if the returned object doesn't fire any events. You have to manually assign it to an event observer using Object.Attach(). Another reason against giving events to data containers ;-) > > Thank you very much for your efforts coding on the interpreter.

End Struct To initialise those callback fields, Gambas needs to know with what you initialise them, so you will need to declare those functions as Extern. Generally, it's OK to have functions assigned to Pointer fields in Structs. > And then "how" do I use those functions in Gambas code ? > You can't (AFAICS!). The only two things you can "call" in Gambas are objects that implement a _call() method or methods of objects (or intrinsic functions which are actually methods of a special hidden object). And Struct fields are neither. However, you could pass that structure to a C library which would be able to call either function type (C or Gambas) successfully but I think you already know that. Therefore, if you don't want to or cannot write a component for what you are doing, you could at least write a little component to work around this limitation: one that calls function pointers for you. That's at least the only solution I can think of... Regards, Tobi -- "There's an old saying: Don't change anything... ever!" -- Mr. Monk From gambas at ...1...

Hi, I have just came back from "holidays", and I haven't read all the pending mails yet. I just want to say that if you have problem with Gambas inheritance and "SUPER" limitations, you can replace inheritance by "composition". I mean : instead of inheriting "Variant[]" or reimplementing it, you can create your own "MyVariantArray" class that embeds a Variant array as a private dynamic variable. Then you will be able to do almost everything you need. Another point: It's not a good idea to reimplement native array classes. These classes must be as fast as possible, they are used everywhere. I don't think that you need an "Update" event for every array in your application, do you? Regards, -- Beno?t Minisini From oitofelix at ...181...

Correct if I'm wrong, but I think that is best exploited when using '_unknown' and '_property' special methods to transparently deliver any method or property request directly to the private dynamic array. This way one don't have to wrap every possible array method or property and the class can be made agnostic of array type. > Another point: It's not a good idea to reimplement native array > classes.

Look at the "MediaPlayer" example, it displays the length of the video/audio file it plays. I admit that playing a file to know its length is a bit stupid. It should be possible to create a GStreamer pipe to just know the length of a multimedia file without playing it. -- Beno?t Minisini ------------------------------------------------------------------------------ Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform _______________________________________________ Gambas-user mailing list Gambas-user at lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user From epost at ...3323...

I'm working on a module for Gambas, fully written in Gambas language, which aims to provide full access to the X Window System's Xlib library through a high-level Gambas-ish interface. I'm in the very beginning, but I've been making progress and so far I've implemented 9% of the features of the C language X interface as described in [1]. However, I'm facing a major problem that needs to be addressed before I get too far. Let's take a look at a particular instance of it. Various Xlib functions accept or return a C 'long' data-type parameter. GCC reports that on my x86 machine 'long' is 4 bytes wide while on my x86_64 machine it's 8 bytes wide instead. AFAIK, Gambas 'Integer' and 'Long' data-type are always 4 and 8 bytes wide, respectively, regardless of architecture. How can I cope with that when declaring external functions and structures? The only solution I could think of is to use Gambas' preprocessor directives, but it isn't practical to put a preprocessor conditional again and again every time I'm declaring something which uses the same C language type: I'd have to do that several hundreds of times! So, I'd suggest to provide absolute C data type equivalents to 'char', 'short', 'int', 'long', 'long long', 'float', 'double' and 'long double', so we could interface smoothly with C libraries and write robust and easy to maintain components for Gambas, entirely in Gambas language. In this case the C compiler would decide what's the wideness of each data type at Gambas' compilation time. One suggestion for their names is: "CChar", "CShort", "CInt", "CLong", "CLongLong", "CFloat", "CDouble" and "CLongDouble". This feature alone would be a great improvement, but not enough. Within C libraries it's a common practice to define conditionally new data types in terms of the native ones. In order to have a complete environment to interface with external libraries inside Gambas, we also need a way to make aliases to native Gambas' data types conditionally. It could well be a preprocessor facility, but that isn't required at all. I'd suggest something that looks like: #If ARCH = "x86" # AliasType("CLong", "XID") #Else # AliasType("CInt", "XID") #Endif #AliasType("XID", "WindowID") #AliasType("XID", "FontID") Thanks in advance.

And even if that does happen I'll write a Wayland Gambas component when the time has come, and that's not now. ;-) Anyway, Xlib programs will still be runnable in Wayland environments for the foreseeable future by some compatibility layer. Also, at the unlikely worst possible case, maybe it's worth to write a component that will still be useful for a few years from now. Would you accept, in the main Gambas' distribution, a well written and documented Xlib component? > Use the "Pointer" datatype each time you see a long. It has the same > behaviour.

It'd be very handy if 'Pointer' was considered by the interpreter as an integer data type like 'Byte', 'Short', 'Integer' and 'Long'. That way one could use any integer function indiscriminately on a Pointer as well, rather than converting it to 'Long' (using 'CLong' function) every time it's an argument for an integer function. That is specially relevant when interfacing with external C libraries, where to make portable Gambas programs one need to treat the C data type 'long' as the Gambas data type 'Pointer'. This means that 'Pointer' isn't meaningful only in pointer contexts but also in ordinary integer contexts. What do you think about this proposed change? Is there any way in which it can be harmful to existing code or interpreter's functionality? Thanks in advance. Ps: In order to make portable Gambas programs which interface with external C libraries, one needs to follow the correct equivalence between C and Gambas integer data types, which is given by the table: [C] [Gambas] char Byte short Short int Integer long Pointer void * Pointer long long Long However, the Gambas Wiki page [1], besides having an incomplete table which does not address 'char', 'short' and 'long long', says that the equivalent of C's 'long' is Gambas' 'Long', what is only true on some 64-bit architectures.

But the Mask property is way weaker than regular expressions. The main point is that you can only describe fixed-length strings (plus/minus the finite number of #/9 fields in your Mask). So wherever you want to forbid "|", you would write "[^|]" but that also consumes any character but "|". So you cannot accept arbitrary strings but only strings of a length equal to the times you forbid the "|" character. Your initial approach was much better but one thing: if you use InStr() each time the TextBox changes, you will scan the whole contents each time they change but you only want to capture inputs, right? If you tell your user not to use Ctrl-V or stuff, you can do: Public Sub txtName_KeyPress() If Key.Text = "|" Then Stop Event End Regards, Tobi -- "There's an old saying: Don't change anything... ever!" -- Mr. Monk From epost at ...3323...

I am running Gambas 3.5.2 now, but perhaps I'll be able to pull the development version and try it out. Another feature request that I think would have been extremely great would be something like a .RichTextInsert() method for the TextEdit control. This way it would be very easy to insert HTML objects like tables, hyperlinks and so on at the cursor's current position. I may ask to much here now, but you don't get without asking :) I know that the QT TextEdit has methods for handling tables. Getting some basic table functionality like that in Gambas' TextEdit would be awesome, e.g. inserting/deleting tables, rows and columns, split and merging cells. I believe this is already built into QT, no?

For example; If we create a single form application (I'll call it FormMain) with only one button on the form (Button1) and the click event of button one looks like this; PUBLIC SUB Button1_Click() DIM hFormMain AS NEW FormMain hFormMain.Show END SUB Each time you click on Button1 a new FormMain will appear on your screen, click on Button1 of the new form and another new form will appear. Now if you have a hidden window and want to bring it into view then that's a different problem. I've done this kind of thing and had my share of trouble with it, give me a bit more info regarding your situation and perhaps I can help you out like others helped me.

Message-ID: <1398886913.16886.YahooMailBasic@...3268...> Hello, ...following "Allegro4" API guide, I wrote an little application in C language (here attached) to play an audio file WAV. ***The application works regularly.*** I tried to transpose that C code in "Gambas code" (here attached), but... it does not work. I don't understand why. What confuses me most is: if I compile that C code like a "shared library" .so, and then I use it by calling with Gambas, very strangely the "shared library" doesn't work. To sum up: - using via Terminal or via Gambas with "Shell" function the C compiled code, it works. - compiling that C code like a "shared library" .so and then calling it via Gambas with "Shell" function, it doesn't work; - using external "Allegro4" functions via pure Gambas code, it doesn't work; Maybe... has anyone an idea why... ? :-X regards vuott (European Union - Italia) -------------- next part -------------- A non-text attachment was scrubbed...

First: What do you mean by "no errors are given"? Did you click on some icon and nothing showed up? Or did you execute gbx3/gbr3 from terminal and it went away silently (because that would be really bad). Could you try to reinstall Gambas on top of that upgrade? Maybe some mime information got overwritten accidentally? Regards, Tobi -- "There's an old saying: Don't change anything... ever!" -- Mr. Monk From vuott at ...325...

It's so strange that. I tranformed many C codes in shared library (i.e. "aplaymidi") and all worked ! > I will look this later.

Hi Tobi, well, I used this line-command in Gambas code: Shell "gcc -o /tmp/allegroWAV.so " & Application.Path &/ "allegroWAV.c '/usr/lib/x86_64-linux-gnu/liballeg.so.4.4.2' -shared -fPIC" Wait > I think you should really write an actual C component for Gambas > programs to interface with. That would save you one or the other problem in the long term. Uhmmm... I understand. Thanks bye vuott
