flash.events.EventDispatcher

EventDispatcher is the base class for all classes in AS3 that dispatch events. The easiest way for you to create a class that can dispatch events is to have your class extend EventDispatcher.

Sometimes however, that is not possible. If, for example, your class already extends a different class that is not descended from EventDispatcher, then you are stuck, because classes and only extend one superclass. The solution in this case is to make your class implement IEventDispatcher, and hand off the functionality of the required methods to an instance of EventDispatcher instead.
