Hi All,

I'm working on a GTK Widget in vala and was wondering if anyone can
point me somewhere or give me a hint as to how I emit signals in vala.

For instance, some event occurs inside of my widget as a result of a
user event or a timed interlude and the widget emits a signal which can
be caught and dealt with.

In one example I want to emit a "selection-changed" signal after
responding to a button-release event. This doesn't seem to be in the
custom widget example code here
http://live.gnome.org/Vala/GTKSample#head-88a57e061a4cc9b5cbe5c5c2f7a41cb78f6cccd2
 but probably should be there as it is an important part of writing custom 
widgets.

BR,
 K
