Class EventDispatchThreadedEventListener

java.lang.Object
  extended by org.fest.swing.listener.EventDispatchThreadedEventListener
All Implemented Interfaces:
AWTEventListener, EventListener

@ThreadSafe
public abstract class EventDispatchThreadedEventListener
extends Object
implements AWTEventListener

Understands a AWTEventListener that ensures all events are handled on the event dispatch thread.

NOTE from Abbot: Applet runners may run several simultaneous event dispatch threads when displaying multiple applets simultaneously. If this listener is installed in the parent context of those dispatch threads, it will be invoked on each of those threads, possibly simultaneously.
