Re: [Visualpython-users] slider

[Bruce S. <bas...@un...>]

Here's a specific example that does what you want:

from visual.controls import *

def update():
     k = float(int(100*(slider1.value)))/100
     title.text = '%s' % k

k = 0
title = label(text='0')
c = controls()
slider1 = slider(x=0, y=0, width=10, length=50,
                  max=6, action=lambda: update())

while 1:
     c.interact()

Perhaps you could suggest how the documentation on these controls could 
be improved? Thanks.
