Beginner's question re. multicolumn lists, events

Using Alex Tweedy's helpful post ...

http://aspn.activestate.com/ASPN/Mail/Message/PythonCard/2718590

I've managed to implement an editable multicolumnlist called MCL  
(with one deviation from Alex's instructions, in case it's relevant  
to the following -- I edited PythonCard/components/multicolumnlist.py  
itself, thinking I probably want this feature in any mcl I create).

It works nicely, the mixin does it's magic, creates an editor and  
saves edits to MCL.items, but my problem is that it only seems to do  
so after a gainFocus event has been sent to MCL when the editor is  
closed. Consequently, using on_MCL_gainFocus to handle changes is  
unreliable.

I've found a way around this by re-entering and then closing the  
edited cell (the second gainFocus event is now aware of the changed  
data), but it's rather inelegant. I can live with it, as the only  
user of the program will be myself, but if anyone can point out a  
better method, it would be appreciated.

Regards,
Terry Maloney
