Re: [Visualpython-users] gtk embedding.

[Bruce S. <Bru...@nc...>]

I don't really follow the details of this, but it doesn't sound like a
good candidate for the standard version of VPython because it is
apparently GTK-specific, and VPython attempts to be
platform-independent.

I'm currently studying how it might be possible to base VPython on
wxPython, in which case the OpenGL canvas could be part of a window,
with cross-platform support for menus etc. My immediate concern is, as
I've commented before, to be able to run VPython on a 64-bit Python on
the Mac, based on Cocoa. On the wxpython-users list, wxPython experts
have been very helpful in my quest, including making a suggestion on
how to get around the very serious problem that the Cocoa interact
loop must be in the primary thread, the roadblock that David Scherer
and I were unable to get around when we tried in 2008.
