def printValue(value):

slider = DirectSlider(range=(0.0,1.0), value=1.0, pageSize=0.1, command = printValue)
slider['extraArgs'] = [slider['value']]

run()

Always 1.0, why?

I think it’s because…

>>> a = 5
>>> b = [a]
>>> a
5
>>> b
[5]
>>> a = 8
>>> a
8
>>> b
[5]
>>>

In other words, you give it the value 1 at first, but it doesn’t make the slider[“extraArgs”] updated anytime you change the slider[“value”] afterwards.

try running the directSlider in a task or update it whenever the value is changed.
