[pygtk] Apportioning space when resizing a box

[Funky Fred]

Actually, there sort of is a way. You can get the actual size of the 
container widget.
I forgot the name of the function to get the actual size, I think it's 
get_allocation, see: 
http://www.daa.com.au/pipermail/pygtk/2001-March/001022.html.
But I think I found an easier funciton, but I don't have the code on me.
Once you have the size of the container widget (your hbox or your table or 
what-have-you), you can then figure out 2/3 * width and 1/3 * width.

Then call set_size_request() on the child widths with the calculated widths 
(2/3 * width, etc)

Then trigger a redraw. I use redraw_children on the container widget, but I 
think there are various ways to trigger a redraw, and I redraw_children 
seems kind of slow. You could try just invaldating or queue_redraw on the 
children widgets your resizing..

If you just want to request 2/3 of the container widgets _requested_ size, 
you should be able to calculate that fairly trivially at the time you make 
all your requests.

then call parent.
