Examples of EventQueue

ae.java.awt.EventQueue
EventQueue is a platform-independent class that queues events, both from the underlying peer classes and from trusted application classes.
It encapsulates asynchronous event dispatch machinery which extracts events from the queue and dispatches them by calling {@link #dispatchEvent(AWTEvent) dispatchEvent(AWTEvent)} methodon this EventQueue with the event to be dispatched as an argument. The particular behavior of this machinery is implementation-dependent. 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:

Sequentially.
That is, it is not permitted that several events from this queue are dispatched simultaneously.
In the same order as they are enqueued.
That is, if AWTEvent A is enqueued to the EventQueue before AWTEvent B then event B will not be dispatched before event A.

Some browsers partition applets in different code bases into separate contexts, and establish walls between these contexts. In such a scenario, there will be one EventQueue per context. Other browsers place all applets into the same context, implying that there will be only a single, global EventQueue for all applets. This behavior is implementation-dependent. Consult your browser's documentation for more information.

charva.awt.EventQueue
The EventQueue class queues "AWT" events, which are used to trigger drawing actions. They can be enqueued using the postEvent() method by any thread (e.g the keyboard reading thread enqueues KeyEvents), but only the event-dispatching thread should call getNextEvent(), because only the event-dispatching thread should do any drawing. This is because the ncurses library is not re-entrant.
SyncEvents are enqueued with a lower priority than other events, and if multiple SyncEvents are found on the queue they are coalesced into a single SyncEvent.

com.sun.jdi.event.EventQueue
Manager of incoming debugger events for a target VM. Events are always grouped in {@link EventSet}s. EventSets generated by the debugger back end can be read here. There is one instance of EventQueue assigned to a particular {@link com.sun.jdi.VirtualMachine VirtualMachine}.
Some events cause the suspension of the target VM - event requests ( {@link com.sun.jdi.request}) with a {@link com.sun.jdi.request.EventRequest#suspendPolicy() suspend policy}of {@link com.sun.jdi.request.EventRequest#SUSPEND_ALL SUSPEND_ALL}or {@link com.sun.jdi.request.EventRequest#SUSPEND_EVENT_THREAD SUSPEND_EVENT_THREAD} and sometimes{@link VMStartEvent}. If these suspensions are not resumed the target VM will hang. Thus, it is always good policy to {@link #remove() remove()} every EventSet from theevent queue until an EventSet containing a {@link VMDisconnectEvent} is read.Unless {@link com.sun.jdi.VirtualMachine#resume() resume} isbeing handled in another way, each EventSet should invoke {@link EventSet#resume()}. @see EventSet @see VirtualMachine @author Robert Field @since 1.3

org.zkoss.zk.ui.event.EventQueue
An event queue. An event queue is a many-to-many 'channel' to publish events and to subscribe event listeners ( {@link EventListener}).
Asynchronous and Synchronous Event Listeners

There are two kinds of event listeners: synchronous and asynchronous. A synchronous listener works the same as a normal event listener (listeners registered to a component ( {@link org.zkoss.zk.ui.Component#addEventListener}). It is executed one-by-one. No two event listeners belonging to the same desktop will be executed at the same time. In additions, it is invoked under an execution (i.e., {@link org.zkoss.zk.ui.Executions#getCurrent} never null).It is allowed to manipulate the components belonging to the current execution.
On the other hand, an asynchronous listener is executed asynchronously in another thread. It can not access the components belonging to any desktop. There is no current execution ( {@link org.zkoss.zk.ui.Executions#getCurrent} is null}.However, it is useful to make the application more responsive when executing a long operation. A typical use is to execute the long operation in an asynchronous listener, and then all other events can be processed concurrently. @author tomyeh @since 5.0.0
