[Discuss-gnuradio] wxWidgets, wxPython, PyOpenGL and OpenGLContext

        Between wxWidgets-2.8 and wxWidgets-2.9, there are some breaking 
changes with the way the OpenGL rendering contexts are handled. You can see the 
difference in the samples/opengl/cube example in the wxWidgets-2.8.11 and 
wxWidgets-2.9.2 svn repo. 

I just have a quick quesion which is, where in gr-wxgui are the calls to 
wxGLCanvas made? 

The GL versions of gr-wxgui don't work with wxWidgets-2.9.2 (64-bit cocoa), due 
to the changes in the way OpenGL rendering contexts are handled in 

Would anyone happen to know which file in the gnuradio code base sets the 
OpenGL rendering contexts, for the wxWidgets GUIs?

Best regards,
