OpenGL + Qt 4.8.4

[cr4y88]

Hello guys...

I'm using Qt 4.8.4 on Windows OS. I'm trying to create an openGL program. I create a widget using ui then promote it into my class which I already derive it from QGLWidget.

I reimplement paintGL, initializeGL. When I try to create a simple GL_QUADS. The result is not what I expected. The quad is so small compared the size of the Widget I created.

Anyone can help me with this?

it seems I found the problem.
solved by reimplementing resizeGL with gluPerspective and gluLookAt

it seems opengl in windows and linux works differently
