Re: [Visualpython-users] Problem integrating VPython5 and PyQt4

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

I myself don't know anything about these other environments into which people 
want to embed Visual, so someone other than me will have to look for a solution. 
I thought that there had been some discussion a few months ago in this list by 
people who had successfully embedded Visual in some larger environment?
