Hi
I have an application built in QT and openGL. I have three widgets in the application and all of the widgets have a separate openGL context.

I want to keep a single openGL context for all of them now. Is there some simple and quick way through which I can change three contexts into one. (ask me for code snippets if I am not clear)

secondly, with the single OpenGL context, would I have a single InitializeGL, resizeGL and paintGL method?

any link to some quick tutorial

regards
