[Gambas-devel] DrawingArea, SetFocus, BUG ?

[Christian Faure]

Hi Benoit,

Working on a ReportDesigner, i get somes problems:

The IDE of ReportDesigner work creating and placing objects in a ScrollView
using a toolbox and allow drag and drop to move objects.

These objects are DrawingArea's

I call a DrawingArea.SetFocus() function to enable each object to handle 
keyboard events.

All work  ok, except when i  move an object outside of visible area and this 
object lose focus, then app crash with:
     QPainter::begin: Cannot paint null pixmap
     QPainter::setWorldMatrix: Will be reset by begin()

Attached file provide a small example of the problem

Thanks
