Swap the Image Buffer - QPixmap - Display 3d data

[SenSej]

Maybe -I already thought about it.

But i started to try out some opengl stuff.
More ore less only the HelloGL example.
I can compile and run, but it crashes imediatly.

How can i check for proper OpenGL installation?

ATI Driver sais - all fine.
I´m able to execute Nate Robin examples. Does this realy needs OpenGL support? Or is it just to learn OpenGl?

So... how can i check it? Thanx in advance
