Comment (by aboudreault):

 Ok, i've made some work in the !SelectionPanel...... but i would like to
 have your opinion. I've complety removed the dependency between the
 !SelectionPanel and the default behavior. In fact, i've create an abstract
 class called Fusion.Widget.!SelectionPanel.!SelectionRenderer (name to be
 discussed) to define A behavior when a selection is done and off course an
 default selection renderer class that inherit from this class. This
 doesn't increase the complexity of the !SelectionPanel at all. If nothing
 is specified in the ApplicationDefinition, the default behavior will be
 used. Now, 2 new possibilities are now available:
  * Pass a simple callback function to the !SelectionPanel
    [[BR]]A simple function can be passed to the widget, and binded with
 MAP_SELECTION_ON (Like your example in the MapGuideTutorial).[[BR]][[BR]]
  * Pass a complex behavior created by a programmer
    [[BR]]A experimented programmer will be able to create his own
 !SelectionRenderer class. This part Fusion can be very complex and
 different for each user (IE: a user may needs to make something at
 initialization of the widget (like the default behavior), create his own
 events, define his own clearSelection method, display results in others
 windows, etc.) So, the user will create his own behavior with the
 !SelectionRenderer class and just pass it to the !SelectionPanel via the
 ApplicationDefinition.

 I really don't know if you'll like the idea... i'm waiting your comments.
