How do I tell when my app gets de-focused

["Garth's KidStuff" <garthskidstuff gmail com>]

Hey all,

Thanks in advance.

I'm creating a Gtk::Entry widget that needs to sit on top of everything else
in my app and so I call set_keep_above(true).  This works great as long as
my app is the focused app, but it stays on top of *everything* -- even other
apps when they get the focus.  Is there a better way to do this?  Or is
there a way to tell when my app loses focus?
