Yes, it should be possible for all events (eg, onces received from X),
and you can do it for a few others. Unfortunately the PyGtk reference
manual does not show if it's okay to return a value or not, so you'd
have to look in the Gtk+ Reference Manual;
http://developer.gnome.org/doc/API/2.0/gtk/GtkWidget.html#GtkWidget-button-press-event
And look at the return value of the signal, if it's boolean, then you
can return True to block the event.
