Method Detail

initEvent

public void initEvent(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.

Specified by:

initEvent in interface org.w3c.dom.events.Event

getBubbles

public boolean getBubbles()

Specified by:

getBubbles in interface org.w3c.dom.events.Event

Returns:

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

getCancelable

public boolean getCancelable()

Specified by:

getCancelable in interface org.w3c.dom.events.Event

Returns:

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.

getCurrentTarget

public org.w3c.dom.events.EventTarget getCurrentTarget()

Specified by:

getCurrentTarget in interface org.w3c.dom.events.Event

Returns:

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

getEventPhase

public short getEventPhase()

Specified by:

getEventPhase in interface org.w3c.dom.events.Event

Returns:

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.)

getTarget

public org.w3c.dom.events.EventTarget getTarget()

Specified by:

getTarget in interface org.w3c.dom.events.Event

Returns:

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

getType

public java.lang.String getType()

Specified by:

getType in interface org.w3c.dom.events.Event

Returns:

event name as a string

getTimeStamp

public long getTimeStamp()

Specified by:

getTimeStamp in interface org.w3c.dom.events.Event

stopPropagation

public void stopPropagation()

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.

Specified by:

stopPropagation in interface org.w3c.dom.events.Event

preventDefault

public void preventDefault()

Prevents any default processing built into the target node from occurring.

Specified by:

preventDefault in interface org.w3c.dom.events.Event
