hi elliot,

i just implemented signal emission hooks for gtk, there's a small
example for that in testgtk "Event Watcher" that traps enter/leave events
on widgets.
for the rest of the sound stuff, i'd like to know where (what cvs module,
e.g. "gtk-sound"?) the sound triggering is going to be setup, so i can
provide you with a basic framework for the gtk-module stuff (to follow
the idea owen proposed in late september, which is actually a very
elegant approach).
there also needs to be some consensus on how the whole thing should
be setup, e.g. whether that module will read an rc file and what
format that should be in, for example something like

sample_path "/usr/lib/samples:/home/timj/samples"

class GtkMenu {
  show ("open-door.au")
  hide ("close-door.au")
}

class GtkButton {
  clicked ("gun-shot.au", "death-cry.au")
}

needs class iteraters/hooks for the type system.
also, the current gtkrc syntax does not feature a `module' keyword
that would load a gtk-sound module (though there's GTK_MODULES= at
least).
