Just a suggestion, but you may find it a lot easier to work with actual
function objects, as opposed to passing a string for the callback, to be
evaluated. When you pass a string it is not a closure and anything in there
will get evaluated when it is executed. So you could change your callback to
this (using one of my favorite python tools: functools.partial):
from functools import partial
callback = partial(AlphaValue, diffuseAmountSlider, "diffuseColorAmount")
the partial() function will take a function and its arguments and wrap them up
into a single callable object, which you can then pass around. You could even
pass more arguments to that new callable, which will be added onto the final
call:
def colors(required, optional1=None, optional2=None):
print required, optional1, optional2
colorFunc = partial(colors, optional2='red')
colorFunc('green')
# green None red
