i believe that you want to use the "map" signal, and return FALSE from
your handler. its been a while since i did this, and i can't find the
code where i did it, so i'm not sure which widget you need to attach
to, but picking one of the lesser known signals like this is the way
to do this. i often do this for menus, for example: when map is
signalled, i redefine the content of the menu, return FALSE and voila:
a totally dynamic menu.
