Hi Aaron,
I've modified your example code in an attempt to make it dynamic based
on a given data set.
The data is a nested dictionary of this form:
data = dict(
containerA= (
dict(CatAA=['A1', 'B1', 'C1'],
CatAB=['A2', 'B2', 'C2'],
CatAC=['A3', 'B3', 'C3'])),
containerB= (
dict(CatBA=['A4', 'B4', 'C4'],
CatBB=['A5', 'B5', 'C5'],
CatBC=['A6', 'B6', 'C6'])),
containerC= (
dict(CatCA=['A7', 'B7', 'C7'],
CatCB=['A8', 'B8', 'C8'],
CatCC=['A9', 'B9', 'C9'])))
I now have to create buttons dynamically based on how the containers and
categories in this data set (and eventually figure out how to also take
the categories' contents into account and generate buttons for those as
well, which can be controlled by Animator instance).
At the moment I'm running into the problem that when I create an
instance of a "WidgetPage" inside a loop and hand it over to your
Animator (see line 113), the bindings go all wrong of course and the
pages all end up at the same memory address, thus overwriting each other.
I tried copy.deepcopy (see line 111) but that seems to barf with class
instances.
Here is my full code:

Any ideas?
Cheers and thanks again for this awesome example!
