Re: [Visualpython-users] How to setting scene window to Close/Dispose?

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

Naming issues: A window containing VPython graphics is a VPython 
"display" object. By default, when you create a sphere or other 
displayable object VPython creates a display object named "scene". In 
documentation you'll find names like "sceneb" or "scene2" as examples of 
displays other than the default one.

from visual import *
box() # by default, a display named "scene" is created, with a box
scene2 = display()
sphere() # this sphere will appear in a second display named "scene2"

It is the case that if you have display.exit = False, closing that 
display doesn't terminate the program. I guess you could watch for that 
display or its contents no longer existing as a signal to stop the program.
