Yes, but those are different glade files. Aren't they? (Sorry I didn't look).

My guess is that the ConfigureNotify X event (or whatever it is called) needs
to be built into gtk. Then if Gtk emits a signal when the X Event is
triggered you could put together a handler that would destroy all of the
existing widgets and then tell libglade to load a new file and create a new
set of widgets. The handler can then do anything application specific to get
things moving along again (special variables, etc.) and you are off.

I don't think putting support for RandR directly into glade is the right
thing. Glade's purpose is to create a gui based on an XML file, nothing more.
Once the gui is created the rest is in the scope of the gui toolkit.

It isn't possible yet AFAIK, until gtk can deal with the RandR stuff. Then we
need a new release of pygtk (if there is anything added/changed in the gtk
interfaces).

We'll probably see this for the Gtk 2.0 release, not before unless people
like jg and keithp take a personal interest. (Hint, Hint) :-)
