Are you using wxGlade? in that case, keeping the GUI code separate makes 
sense, but I'm not sure it does otherwise. That's one reason I haven't 
used GUI-builders...

I think keeping all the "Real" functionality separate from the GUI is 
good, but you don't' need to bind the events there. The actual events 
can get bound in with the GUI classes, and the handlers then make calls 
into the the module that does the real work (The Model in MVP or MVC).

exactly -- SIZE event handlers are a strictly gui function -- keep them 
with that code.

This is a good one (and points you to others)
