Hello to everybody

I have a basic question: what's the clean approach for setting callbacks in 
window1 to a drawing area in window2 if window2 IS NOT SHOWN YET? 

I see that show () on window2 before creating the drawing area is fine, but 
I'd like to show window2 only later on, not when I define callbacks drawing 
on it but when there will actually be something to draw.

I was thinking of using a drawing area option ref, but I don't know whether is 
this a good idea. Would anybody have a hint for that?
