Actually, they are propagated from child to parent. So there is
effectively no way to prevent them being seen by the child. 
(Except by calling gtk_signal_handler_block() for each child
individually)

What returning TRUE means is that the event shouldn't be propagated
to the widget's parent. But other handlers for the current widget
will still be run. You want to call gtk_signal_emit_stop_by_name()
in addition to returning TRUE.
