[PyQt] Help about the use of OpenGL with PyQt

[projetmbc]

 >>> Your problem is with your OpenGL syntax. Simply change GL.GL_QUADS 
(which draw quadrilaterals) with GL.GL_TRIANGLES (self evident). Also,

as follows

Thanks and sorry for this simple problem but I'm a real newbie with OpenGL.

Where can I find documentations showing what kind of objects I can draw 
with OpenGL ?

Best regards and thanks a lot.
