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 0N/A // used in handleException 0N/A // Note: We stop dispatching via a flag rather than using 0N/A // Thread.interrupt() because we can't guarantee that the wait() 0N/A // we interrupt will be EventQueue.getNextEvent()'s. -fredx 8-11-98 0N/A // wait for the dispatcher to complete 0N/A // fix 4122683, 4128923 0N/A // Post an empty event to ensure getNextEvent is unblocked 0N/A // We have to use postEventPrivate instead of postEvent because 0N/A // EventQueue.pop calls EventDispatchThread.stopDispatching. 0N/A // Calling SunToolkit.flushPendingEvents in this case could 0N/A // lead to deadlock. 0N/A * This synchronized block is to secure that the event dispatch 0N/A * thread won't die in the middle of posting a new event to the 0N/A * associated event queue. It is important because we notify 0N/A * that the event dispatch thread is busy after posting a new event 0N/A * to its queue, so the EventQueue.dispatchThread reference must 0N/A * be valid at that point. 0N/A * Event dispatch thread dies in case of an uncaught exception. 0N/A * A new event dispatch thread for this queue will be started 0N/A * only if a new event is posted to it. In case if no more 0N/A * events are posted after this thread died all events that 0N/A * currently are in the queue will never be dispatched. 0N/A * Fix for 4648733. Check both the associated java event 0N/A * queue and the PostEventQueue. 0N/A return false;
// AppContext.dispose() interrupts all 0N/A // Threads in the AppContext 0N/A // Can get and throw only unchecked exceptions 869N/A // don't rethrow the exception to avoid EDT recreation 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. If event is 0N/A * for some component from another heavyweight than modalComp, 0N/A * it is accepted. If heavyweight is the same - we still accept 0N/A * event and perform further filtering in LightweightDispatcher 0N/A // Exclude this object from modality and 0N/A // continue to pump it's events. 0N/A // 5.0u3 modal exclusion 0N/A // Exclude this window and all its children from 0N/A // modality and continue to pump it's events.
