Returns true if the calling thread is the current AWT EventQueue's dispatch thread.

if no previous push was made on this EventQueue

Warning: To avoid deadlock, do not declare this method synchronized in a subclass. Any pending events are transferred to the previous EventQueue for processing. Stops dispatching events using this EventQueue. NewEventQueue - an EventQueue (or subclass thereof) instance to be use Any pending events are transferred to the new EventQueue for processing by it. Replaces the existing EventQueue with the specified one. Public void push( EventQueue newEventQueue) The event currently being dispatched, or null if this method is invoked on a thread other than an event dispatching thread If this method is invoked from another thread, null will be returned. Note that this method should only be invoked from an application's event dispatching thread. This is useful if a method needs access to the event, but was not designed to receive a reference to it as an argument. Returns the the event currently being dispatched by the EventQueue associated with the calling thread. The timestamp of the last InputEvent, ActionEvent, or InvocationEvent to be dispatched, or System.currentTimeMillis() if this method is invoked on a thread other than an event dispatching thread If this method is invoked from another thread, the current system time (as reported by System.currentTimeMillis()) will be returned instead. May add timestamps to additional event types. Only InputEvents, ActionEvents, and InvocationEvents have timestamps however, future versions of the If no events have yet been dispatched, the EventQueue's initialization time will be returned instead.In the current version of the If an event with a timestamp is currently being dispatched, its timestamp will be returned. Returns the timestamp of the most recent event that had a timestamp, and that was dispatched from the EventQueue associated with the calling thread. Public static long getMostRecentEventTime() The manner in which the event is dispatched depends upon the type of the event and the type of the event's source object:Įvent - an instance of, or a subclass of it Protected void dispatchEvent(AWTEvent event)ĭispatches an event. The first event of the specified id or null if there is no such event if another thread has interrupted this thread This method will block until an event has been posted by another thread. Removes an event from the EventQueue and returns it. TheEvent - an instance of, or a subclass of it If there is an existing event on the queue with the same ID and event source, the source Component's coalesceEvents method will be called. Posts a 1.1-style event to the EventQueue. Returns the first event with the specified id, if any. Returns the first event on the EventQueue without removing it. Removes an event from the EventQueue and returns it.Ĭauses runnable to have its run method called in the dispatch thread of the EventQueue. Consult your browser's documentation for more information.įor information on the threading issues of the event dispatch machinery, see This behavior is implementation-dependent. Other browsers place all applets into the same context, implying that there will be only a single, global EventQueue for all applets. In such a scenario, there will be one EventQueue per context.

Some browsers partition applets in different code bases into separate contexts, and establish walls between these contexts. That is, if AWTEvent A is enqueued to the EventQueue before AWTEvent B then event B will not be dispatched before event A. That is, it is not permitted that several events from this queue are dispatched simultaneously. The only requirements are that events which were actually enqueued to this queue (note that events being posted to the EventQueue can be coalesced) are dispatched: The particular behavior of this machinery is implementation-dependent. Method on this EventQueue with the event to be dispatched as an argument. It encapsulates asynchronous event dispatch machinery which extracts events from the queue and dispatches them by calling EventQueue is a platform-independent class that queues events, both from the underlying peer classes and from trusted application classes.
