Yes and no. I haven't checked the specs at freedesktop.org etc. (yet), 
but I do know exactly what XLib event I'm looking for, and how I might 
catch it if I weren't using a toolkit. Using XLib event calls directly 
in a Gtk application is probably a bad idea, however, as Gtk has its own 
way of dealing with events.
