What is the best way to create a nested opengl canvas

Question

I would like to write a library that draws some opengl on a given window handle.

How can I initialize an opengl-context inside a given window? Is it possible to do that platform independent using SDL or some other library?

Answer 1

Qt provides a very good, cross platform mechanism for opening an OpenGL context and drawing into it. For details, see QtOpenGL.

Answer 2

You could use Open Producer or the OpenSceneGraph to do it as well.
