[Glade-users] Newbie Question: Different widgets in one part of the main window

[graef websphere de (Carsten Gräf)]

Hey there,

I wonder how (and if) you can do this using glade:

Suppose you got a main (toplevel) window consisting of
a left and a right box. Now, depending of what I do in the
left box, I want a ctree widget or a a notebook or something 
else in the right box (but not in a new window!). 

So the problem is: If I add, say, a notebook in the right box with
glade, how can I possibly add a ctree widget there as well (and switching
the shown object in my application)?

Thanx for your help!!!
Carsten

P.S. I'm using php-gtk with glade support on a windows system.
