Hi.
I found this example in this list:
http://groups.google.com/group/pyglet-users/browse_thread/thread/230885dcdaee0394/0e3628eef014e3a1?lnk=gst&q=wxpython#0e3628eef014e3a1
And now I'm using something like this, but don't know if it is a good
way to do it.

Does anyone have an example showing how to use Pyglet and wx.Python
together in the same app?
Thanks!
