Thanks Dan, but I was really looking for something much more elaborate :-) The structure of the Pmw library/widgets is difficult to describe, but I found it an amazingly powerful library that allow some pretty nice (and easy) extensions once you understood how it worked. Whilst I have never delved into the inner workings, I might try some form of a basic port of the code to PyQt (assuming there is nothing else available) - I'll have to look into it, because I suspect it might be a pretty big job! It will certainly stretch my knowledge of Python! :-)
