I'm creating a scientific visualization application with rather high

C++/OpenGL and a python interface to the rendering engine. Now I'm
looking to build a GUI in python with the rendering engine as an
integrated window. I will most likely use wxPython for the GUI and I
know it has support for adding an OpenGL canvas.
Maybe including wxWidgets in the C++ program and just using the
wxPython-created canvas ID there will somehow be possible? I'll look
into that but any help or ideas are most welcome.
I banged my head on this for quite a while trying to integrate
OpenInventor and wxPython (and later PyGTKGLext). Basically, the OpenGL
callers don't need to know what the current canvas is. You tell the
canvas to activate itself, it tells OpenGL "hey, I'm the current canvas
now". Then OpenGL commands draw themselves on that canvas. It's really
much simpler than I initially thought. You just have to make sure that
there's a Python function somewhere in your begin-rendering sequence
that activates the canvas before OpenGL calls begin.
