[Qt-interest] When OpenGL Initialization happens? (QGraphicsScene - OpenGL glBegin/glEnd)

[fungos]

I was doing some tests with opengl in both Qt and Win32 and then I
found my problem. The problem is that opengl context is not
initialized when I try to use it inside Qt (by initializing my
library).

My question now is, when opengl initialization will happen in Qt? Just
when I try to use my opengk QGraphicsScene inside a QGraphicsView? Is
there a way to initialize opengl context with QApplication
initialization?

Attached are two samples using opengl, TestGL is the Qt test (using
QtCreator) and TestGL2 is the Win32 test (using Code::Blocks).

Thank you
