[Qt-jambi-interest] ARGB Visuals in QT Jambi ?

[Børge Austvold]

Hi Gunnar,

Well I managed to get this up and running using native code to 
initialize the QApplication. I can now create a fullscreen application 
that paints transparent on the screen, cool! One thing is still missing, 
if I try to do this with a QGLWidget the screen turns black, QWidget is 
ok... any idea why GL painting fails on this ?
