Using Combox Box

I am very, very pleased with my first use of the ComboxBoxEntry in pygtk,
so I want to try  it again, but this time, with a little more work.  I
want the source of the strings to be a database, and I would ideally want
those strings to be completely refreshed every time the list is popped
down.

I am probably wrong, but I figured that the way to do this would be to get
to the button widget part of things, and look for a 'pressed' signal.  I
can't figure out how to get the button widget, though ... the 'child'
attribute gets you the Entry widget, not the button (which I did use, in
my first attempt, and that worked great).

Can I get some help in doing the task I want to accomplish?  Should I
perhaps not go after that button?  Or, how would I detect that the popdown
list is about to pop down?

Thanks
