EventTargetpublic interface EventTarget 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 .

Methods Summary |
---|
public void | addEventListener(java.lang.String type, org.w3c.dom.events.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(org.w3c.dom.events.Event evt)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(java.lang.String type, org.w3c.dom.events.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.
