Hey guys, I just saw this thread.
Last week I was able to get some basic integration between wxPython
and pyglet - some sample code is attached below. Although this
program runs just fine, my actual usage is more complex and I've
encountered some issues. Namely:
1. sometimes calling set_current() on both the pyglet Context and on
the wx.GLCanvas results in a GL "invalid operation" exception
(primarily on win32, not on OS X); however, I seem to need to call
both in order to get correct rendering. (For example, pyglet's text
rendering won't work until set_current has been called.)
2. sometimes the window is blank until I resize, regardless of how
many times I swap buffers (via pyglet or wx), or how many times I draw
into the window or interact with the GL area with my mouse.
If anyone has any suggestions or ideas on how best to fix/debug these
issues, I'd love to hear from them.
Thanks,
Peter
