Glwidget in qt issue with coordinates

I am running qt 4.7 on Mac OS X and t开发者_如何学运维he coordinates are being drawn wrong for glwidget. I've tried it on a Fedora box and it works fine. Does anyone know if there's a bug in glwidget for mac? or how I can fix it?

Found a solution: I had original installed only the libs, but when I installed the framework with qtcreator it worked!!!
