Methods Summary
public booleangetBubbles()

return
true iff this Event is of a class and type which supports bubbling. In the generic case, this is True.

        return bubbles;
    
public booleangetCancelable()

return
true iff this Event is of a class and type which (a) has a Default Behavior in this DOM, and (b)allows cancellation (blocking) of that behavior. In the generic case, this is False.

        return cancelable;
    
public org.w3c.dom.events.EventTargetgetCurrentTarget()

return
the Node (EventTarget) whose EventListeners are currently being processed. During capture and bubble phases, this may not be the target node.

        return currentTarget;
    
public shortgetEventPhase()

return
the current processing phase for this event -- CAPTURING_PHASE, AT_TARGET, BUBBLING_PHASE. (There may be an internal DEFAULT_PHASE as well, but the users won't see it.)

        return eventPhase;
    
public org.w3c.dom.events.EventTargetgetTarget()

return
the EventTarget (Node) to which the event was originally dispatched.

        return target;
    
public longgetTimeStamp()

	return timeStamp;
    
public java.lang.StringgetType()

return
event name as a string

        return type;
    
public voidinitEvent(java.lang.String eventTypeArg, boolean canBubbleArg, boolean cancelableArg)
The DOM doesn't deal with constructors, so instead we have an initializer call to set most of the read-only fields. The others are set, and reset, by the event subsystem during dispatch.

Note that init() -- and the subclass-specific initWhatever() calls -- may be reinvoked. At least one initialization is required; repeated initializations overwrite the event with new values of their parameters.


                                                                                                                        
          
                         
    
            type=eventTypeArg;
            bubbles=canBubbleArg;
            cancelable=cancelableArg;
            
            initialized=true;
    
public voidpreventDefault()
Prevents any default processing built into the target node from occurring.

        preventDefault=true;
    
public voidstopPropagation()
Causes exit from in-progress event dispatch before the next currentTarget is selected. Replaces the preventBubble() and preventCapture() methods which were present in early drafts; they may be reintroduced in future levels of the DOM.

        stopPropagation=true;
