[Visualpython-users] WxPython + vpython

[Bruce P. <bap...@te...>]

Another approach (that I've not tried) is possibly to set up the VPython 
program as a server and control it from another process running wxPython. 
I've written a server that uses VPython and also a VBA (from Excel) routine 
that controls the VPython display. As they are running in separate 
processes, they don't interfere with each other. (I also made the server 
routine multi-threaded to allow it to continue updating the display while 
responding to calls from VB). I've been thinking of moving the UI from 
Excel VBA (which is a great rapid prototype platform) to wxPython -- I'd be 
interested to hear if anyone knows of problems with (or has tried) the 
multi-process approach.
