Hi Markus, Pmw has a ComboBox but it's ugly IMO. Tix also has one -- but it's not much different than the Pmw one. I created one and put it in a Tkinter.py file. You can see mine here: http://www.seritt.org/pub/tkinter/Tkinter-03132005.py -- I can honestly say it's almost fully functional :-)
Seriously though, you can use the Listbox for almost anything you would need a combobox for. In my mind, it's good for tight spaces (I'm sure someone on this fine board will add something or disagree with me), looks and little else.
