[Zope] Using the Tree Widget

[David VanKirk]

Yea I saw that and started working or writing my own function, but
there are some other things that didn't work for me.  I guess I don't
know how the widget calls that function.

Does it call that function once, or does it call it for each node?
Does the widget pass some info to the function (or can it be done) so
that the function knows what node the widget wants children for?  Does
the widget expect a certain type of object list to be returned from
the function?  How would I format the returned object to be displayed
if it's not in the standar Zope Object format?
