How are you using the function gtk_widget_hide?

Rather, how are you showing the widgets? I think if you are using
gtk_widget_showall() on the vbox, it will show all the children as well,
which would explain why your use of gtk_widget_hide()  didn't work. You
might want to try showing the component widgets separately, then when you
hide the widget in question it should disappear (and the vbox/main window
resize), but not be distroyed. I believe if you destroy a widget and then
try to access it again it does not get reinstantiated, i.e., once it's gone,
it's GONE.  So if you plan to reuse the widget, it would be better to just
hide it.

Hopefully this helps.
