Re: Making Signal For A Widget.

[Tristan Van Berkom <vantr@touchtunes.com>]

You might do well to note also that gtkwidget.c is like a HUB for all 
theese events.
As input, you get your GdkEvents and as output, you have a bunch of 
basic signals
that are "emmited" at the GtkWidget level and handlers are "implemented" 
by various
subclasses.

you should probably read this:
   
http://developer.gnome.org/doc/API/2.0/gdk/gdk-Event-Structures.html#GdkEventButton

when a "clicked" signal is emitted (by the GtkButtonClass); the mouse 
button has
already been "released". now wether you mean the "Left button", the 
"button down" or
"button press" by "First" is an entirely different question.

Hope this helps,
