Event handlers can choose to 0N/A * block this event pump at any time, but should start a new pump (<b>not</b> 0N/A * a new EventDispatchThread) by again calling pumpEvents(Conditional). This 0N/A * secondary event pump will exit automatically as soon as the Condtional 0N/A * evaluate()s to false and an additional Event is pumped and dispatched. 0N/A * @author Amy Fowler 0N/A * @author David Mendenhall 2518N/A * Must be called on EDT only, that's why no synchronization 2518N/A // EventQueue may change during the dispatching 4537N/A // Threads in the AppContext 0N/A * filter out MouseEvent and ActionEvent that's outside 0N/A * the modalComponent hierarchy. 0N/A * KeyEvent is handled by using enqueueKeyEvent 0N/A * Modal internal frames are handled separately.
