All Implemented Interfaces:

TaskSynchronizationManager

public class InterceptingEventQueue
extends java.awt.EventQueue
implements TaskSynchronizationManager

An event queue implementing the TaskSynchronizationManager interface. When AWT events are received, each invocation event is wrapped in a synchronizing object. If the queueTasks toggle is on, each invocation event is queued until the releaseTasks() method is called. When runTasks() is called, all queued events are executed.
