Each widget goes through several stages before it is actually displayed on 
the screen. When a widget tree is "realized" its size is calculated, then 
it is "mapped" which is when it is actually shown on the screen. So maybe 
you try widget_realize() before you ask for the size.

Redrawing is done in an idle handler in the main loop. So this moving of 
windows will never show AFAIK.

Hope this is helps,
Axel.
