Modifier and Type | Method and Description |
---|---|
void |
addEventListenerNS(java.lang.String namespaceURI,
java.lang.String type,
EventListener listener,
boolean useCapture,
java.lang.Object evtGroup)
This method allows the registration of an event listener in a
specified group or the default group and, depending on the
useCapture parameter, on the capture phase of the DOM
event flow or its target and bubbling phases. |
boolean |
dispatchEvent(Event evt)
This method allows the dispatch of events into the implementation's
event model.
|
EventSupport |
getEventSupport()
Returns the event support instance for this node, or null if any.
|
NodeEventTarget |
getParentNodeEventTarget()
Returns the parent node event target.
|
void |
removeEventListenerNS(java.lang.String namespaceURI,
java.lang.String type,
EventListener listener,
boolean useCapture)
This method allows the removal of an event listener, independently of
the associated event group.
