It's been a while since I've looked at it or used it (haven't been  
doing an GUI programming recently). I should have said to put your  
code in the __init__ method after the call to init since the init  
method is regenerated each time.

You mentioned you were new to Python - you really need to learn more  
(specifically about inheritance) before you can fully understand  
this. The GladeWindow provides a show method but you can write your  
own show method that would get called instead of it. If you want the  
code to just be called once, using the __init__ method is appropriate  
but if your window is repeatedly shown/hidden and you want the code  
executed each time the window is shown.
