  Two things spring to mind: you could create a dummy holder 
(not visible) for the alternate widget.  Then have the widget to 
be replaced inside a single Box container.  Then use the widget 
reparent call to put the old one inside the hidden holder, and 
then the new one inside the empty Box.

  I have a nasty feeling that when you do this, though, empty 
parents get automatically deleted, so you could have a bit of a 
fight on your hands ...


  The other (easier!) thing I thought of was simply this: put a 
small GtkNotebook where you want the widget(s) to be.  Then, 
place each of your alternate widgets into a separate page in 
this notebook - only one will be visible at any one time.

  All you need do is set the 'tabs' visibility to 'off' 
(there's a notebook call to do that before showing it), so the 
fact that there's a notebook there is transparent (if you're 
using glade, manage the design etc. with tabs on to make it 
easier, then just turn 'em off before saving).

  The notebook size will reflect the max. size of any of the 
widgets/pages.  You can then select the correct visible page 
number (from your code) at will.
