[Qt-interest] QPainter issues with OpenGL ES v2

[Gabriel M. Beddingfield]

I have a QGLWidget that I can't get to display on OpenGL ES 
v2 (MeeGo "trunk").  The code works fine with a full OpenGL 
implementation.  The widget is making no direct OpenGL 
calls, instead using QPainter to paint the scene. 
Single-stepping through the code, the GLESv2 driver code is 
being executed.

Anybody have any clues on where the problem might be?  I've 
been fighting it for several days.  I'm currently pruning 
the code[1] to try and create a simple test case.

The docs mention something about using a QGraphicsView when 
using QPainter.[2]  I am not doing this... but this seems to 
be talking about something else (e.g. getting a QPushButton 
to render with OpenGL calls)
