[PyOpenGL-Users] Anyone using wxPython's GLCanvas on Linux?

[Mike C. F. <mcf...@ro...>]

I've just discovered yet another "how can that possibly not work" issue 
with wxPython + PyOpenGL under RHLinux 8.0, which is making me wonder:

    * Does wxGLCanvas just not work on Linux?
          o Has anyone else really used it (not just running the demos,
            actually used it, doing any of the things decribed below)?
          o Did you discover and work around these problems (described
            below)?
          o Did the problems not show up at all?
    * Is there something wrong with how I'm doing SetCurrent() for the
      context?
          o I'm just calling  wxGLCanvas.SetCurrent(), which AFAICS is
            the correct thing to do.

Basically, here are the things that are not working:

    * Display-lists can't be generated, glGenLists always returns 0
    * glInitMultitextureARB returns 0 under wxPython contexts, but 1 for
      GLUT contexts (same machine, same everything else).  In other
      words, the extension isn't recognised for wxPython contexts but is
      for GLUT contexts
    * gluBuild2DMipmaps seg-faults under wxPython, works fine under GLUT

The symptoms would all suggest that (Py)OpenGL isn't recognising the 
current context (display-lists are context-specific, as are extensions 
and texture-objects), but I can't imagine what would cause such a thing 
in my code.  I've checked, and I'm definitely calling

        wxGLCanvas.SetCurrent(self)

on the wxGLCanvas instance.

So, I'm wondering, am I just the first person to really use the wxPython 
wxGLCanvas?  My testing on Linux has never been particularly extensive, 
but I can't imagine that anyone really using wxGLCanvas on this platform 
hasn't noticed such an effect.

Oh, same code, same versions of wxPython and PyOpenGL works fine on 
Win2K, and as noted above, all the code works fine with the GLUT 
contexts on Linux (and Win2K).

So, is this an isolated incident, or am I tredding upon new ground here?
