The EventTarget interface is implemented by all Nodes in an implementation which supports the DOM Event Model. Therefore, this interface can be obtained by using binding-specific casting methods on an instance of the Node interface. The interface allows registration and removal of EventListeners on an EventTarget and dispatch of events to that EventTarget.

Method from org.w3c.dom.events.EventTarget Summary:
addEventListener, dispatchEvent, removeEventListener

Method from org.w3c.dom.events.EventTarget Detail:
public void addEventListener(String type, EventListener listener, boolean useCapture) This method allows the registration of event listeners on the event target. If an `EventListener` is added to an `EventTarget` while it is processing an event, it will not be triggered by the current actions but may be triggered during a later stage of event flow, such as the bubbling phase. If multiple identical `EventListener`s are registered on the same `EventTarget` with the same parameters the duplicate instances are discarded. They do not cause the `EventListener` to be called twice and since they are discarded they do not need to be removed with the `removeEventListener` method.
public boolean dispatchEvent(Event evt) throws EventException This method allows the dispatch of events into the implementations event model. Events dispatched in this manner will have the same capturing and bubbling behavior as events dispatched directly by the implementation. The target of the event is the `EventTarget` on which `dispatchEvent` is called.
public void removeEventListener(String type, EventListener listener, boolean useCapture) This method allows the removal of event listeners from the event target. If an `EventListener` is removed from an `EventTarget` while it is processing an event, it will not be triggered by the current actions. `EventListener`s can never be invoked after being removed. Calling `removeEventListener` with arguments which do not identify any currently registered `EventListener` on the `EventTarget` has no effect.

Method from org.w3c.dom.events.EventTarget Detail:

 public  void addEventListener(String type,
    EventListener listener,
    boolean useCapture)This method allows the registration of event listeners on the event
target. If an EventListener is added to an
EventTarget while it is processing an event, it will not
be triggered by the current actions but may be triggered during a
later stage of event flow, such as the bubbling phase.

 If multiple identical EventListeners are registered
on the same EventTarget with the same parameters the
duplicate instances are discarded. They do not cause the
EventListener to be called twice and since they are
discarded they do not need to be removed with the
removeEventListener method.

 public boolean dispatchEvent(Event evt) throws EventExceptionThis method allows the dispatch of events into the implementations
event model. Events dispatched in this manner will have the same
capturing and bubbling behavior as events dispatched directly by the
implementation. The target of the event is the
 EventTarget on which dispatchEvent is
called.

 public  void removeEventListener(String type,
    EventListener listener,
    boolean useCapture)This method allows the removal of event listeners from the event
target. If an EventListener is removed from an
EventTarget while it is processing an event, it will not
be triggered by the current actions. EventListeners can
never be invoked after being removed.

Calling removeEventListener with arguments which do
not identify any currently registered EventListener on
the EventTarget has no effect.
