[Gambas-devel] gtk 050120 / QT bugs

[Daniel Campos]

Hi:


This is a new pre-alpha version of the GTK+ component:

- I've implemented some things like the "drop part" from dnd
- Now you have a good clipboard support
- Cursors
- Less buggy picture and image classes.
- Some new widgets: TextArea and ProgressBar.
- Some bugs fixed, but I have to rewrite some of the form deletion code, 
as your application
may still crash when closing the main formulary, under still unknown 
circumstances (mistery :-)).
- GTK+ seems to be able to show full color cursors, while QT translates
it to b&w, at least using X.org server.
- The "PictureMask" property from the "Form" class has been implemented, 
so now allows
to create transparent forms with gtk+.
- The Huygens mission landed sucessfully on Titan :

I've found some bugs in the gb.qt "Cursor" implementation:

1) If you execute:

...
Dim hCur As Cursor
hCur=New Cursor(Picture["myicon"])
Me.Cursor=hCur
...

You got a "1 Allocations not freed" error

2) If you execute:

...
Dim hCur As Cursor
hCur=New Cursor(Picture["myicon"],30,20)
Me.Cursor=hCur
...

And "30" and "20" are bigger that the real icon size, you got
an error from QT:

"X Error: BadMatch (invalid parameter attributes) 8
  Major opcode:  93
  Minor opcode:  0
  Resource id:  0x300024e
X Error: BadCursor (invalid Cursor parameter) 6
  Major opcode:  2
  Minor opcode:  0
  Resource id:  0x300024f"


This should be checked, and "if X>picture.Width then X=Picture.Width-1"
