How can I determine the max allowable WX_GL_DEPTH_SIZE for a wx GLCanvas?

Question

I am creating a wx.Frame with a GLCanvas. On some platforms, setting the WX_GL_DEPTH_SIZE attribute of the canvas to 32 works fine. On another platform, I just get a blank frame (the GLCanvas doesn't render) unless I reduce the depth size to 16. Is there an easy way in the calling code to determine the allowable values for the depth size?

Answer 1

The only solution I found is to use GLCanvas method IsDiplaySupported, however it seems that this method is available in wxPython 2.9 and not older versions.

Answer 2

Are you running Linux? Perhaps you could get that information from the table of display modes that glxinfo -t outputs.
