I've created a ghetto-ized ComboBox that should work nicely for Tkinter
(unfortunately no dropdown capabilities yet).
I've found why it's such a pain in the @ss to create one. You have to
re-create common methods and make sure they're mapped to the right
component (inside this widget are frame, entry, listbox, and scrollbar
widgets). I tried to look for ways I could inherit some methods from
other widgets but couldn't think of how to do it in an efficient way.
If anyone has suggestions to improve it, please respond... Remember...
I'm a traditional c/c++ turned python programmer who forgets that there
usually is a better, faster more graceful way to do things with Python
than with C/C++/Java.

class ComboBox:
Why not extend an existing Tkinter widget? This way you get at
least the geometry (pack, grid etc) methods thown in for free!
class ComboBox(Frame):
def __init__(self, parent, *args, **kw):
Frame.__init__(self, parent, *args, **kw)
You could extend Entry above is just an example...
Also worth pointing out are a couple of ComboBox's out there already
Pmw includes one as does Tix (IIRC)
Cheers,
Martin.
