Re: [Visualpython-users] working visualpython + wxPython program?

[Patrick B. <pat...@sp...>]

Jonathan, thanks for the reply.

For the kinds of simple things I'd like to do, visual's 3D window 
wouldn't need to be embedded within the wxPython app, it would simply 
need to be controlled by it. Preferably in a direct manner, but it 
sounds from your answer like that wouldn't be possible either. Maybe I 
could start the visual part in its own process and communicate with it 
via a socket; maybe even just sending the visual "commands" (e.g. 
"cylinder(axis=(5,0,0), pos=(3,2,1))" etc.) through the socket and 
having the receiving end just exec() them. Of course that would mean I'd 
have to learn how to use sockets ;) ...
