[Qt-interest] How does Qt manage the OpenGL multiple render contexts

[Joe Liu]

Hi,

I just want to learn more detail about Qt OpenGL;

Does it create new thread for each QGLWidget?
Otherwise, how can it know what state of which RC the user are trying to
modify;

merely out of curiosity;

BTW, is the Qt OpenGL a new implementation, like glew or anything else?
And does Qt OpenGL support the latest GL features, like V2.0?


Thanks


Joe
