Re: [Visualpython-users] event driven programming

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

This code fragment displays a blue sphere named ball, then enters an 
infinite loop looking for mouse events. If you click on the ball, the 
ball is "picked" and its color is changed to red:

from visual import *
ball=sphere(color=color.blue)
while True:
    if scene.mouse.events:
        m = scene.mouse.getevent()
        if m.pick is ball:
            ball.color = color.red
