CATEVENTDISPATCHER

Name

CatEventDispatcher

Purpose

The purpose of this utility routine is to intercept the event
callbacks from widgets and pass the "event" on to an object
EventHandler method. The EventHandler method must be written
with one positional parameter: the event structure that comes
from the widget. Note that the "name" of the object is added
as a field in every event structure.
