Re: Gdk 'keys-changed' signal not emitted

[Tarek <tekbase gmail com>]

I tried changing it to a GtkWindow and still cant catch the signal.
Anyway to know if the signal is emitted at all in the first place?
maybe a GdkEventFilter?

Anyways, it seems the api documentation is a little confusing here and
might need some clearing up.

This was my first reference:
http://developer.gnome.org/doc/API/2.0/gdk/gdk-Keyboard-Handling.html#GdkKeymap-keys-changed

Thanks.
