You can do this using composition. Store an instance of EventDispatcher as a
private member variable called m_dispatcher. Then implement IEventDispatcher
in MlEditmanager. Delegate addEventListener, dispatchEvent,
removeEventListener and hasEventListener to m_dispatcher.
public class MlEditmanager extends EditManager implements IEventDispatcher
{
private var m_dispatcher:IEventDispatcher;
public function MlEditmanager()
{
this.m_dispatcher = new EventDispatcher();
}
public function addEventListener(type, listener, useCapture, priority,
useWeakReference)
{
this.m_dispatcher.addEventListener(type, listener, useCapture,
priority, useWeakReference);
}
public function removeEventListener()
{
// Implement in the same way
}
}
HTH.
