<P>
In your interface, you want to handle a lot of events in the
subwidgets that make up your mega-widget. For instance, when
somebody presses the button in a TixArrowButton widget, you want the
button to handle the event. The <tt>SetBindings</tt> method is used to
creates event bindings for the components inside the mega-widget. In
our TixArrowButton example, we use the bind command to specify that
the method <tt>tixArrowButton:IncrCount</tt> should be called each
time when the user presses the first mouse button. As a result, we
can count the number of times the user has pressed on the button
(obviously for no better reasons than using it as a dumb example).
