Defined by TextEvent
Defined by Event
Indicates whether an event is a bubbling event. If the event can bubble,
this value is true; otherwise it is false.
When an event occurs, it moves through the three phases of the event flow: the capture phase, which flows from the top of the display list hierarchy to the node just before the target node; the target phase, which comprises the target node; and the bubbling phase, which flows from the node subsequent to the target node back up the display list hierarchy.
Some events, such as the activate and unload
events, do not have a bubbling phase. The bubbles property
has a value of false for events that do not have a bubbling
phase.
read onlycancelable:Bool
Indicates whether the behavior associated with the event can be prevented.
If the behavior can be canceled, this value is true;
otherwise it is false.
read onlycurrentTarget:Any
The object that is actively processing the Event object with an event listener. For example, if a user clicks an OK button, the current target could be the node containing that button or one of its ancestors that has registered an event listener for that event.
read onlyeventPhase:EventPhase
The current phase in the event flow. This property can contain the following numeric values:
- The capture phase(
EventPhase.CAPTURING_PHASE). - The target phase(
EventPhase.AT_TARGET). - The bubbling phase(
EventPhase.BUBBLING_PHASE).
Inherited Methods
Defined by Event
Duplicates an instance of an Event subclass.
Returns a new Event object that is a copy of the original instance of
the Event object. You do not normally call clone(); the
EventDispatcher class calls it automatically when you redispatch an
event - that is, when you call dispatchEvent(event) from a
handler that is handling event.
The new Event object includes all the properties of the original.
When creating your own custom Event class, you must override the
inherited Event.clone() method in order for it to duplicate
the properties of your custom class. If you do not set all the properties
that you add in your event subclass, those properties will not have the
correct values when listeners handle the redispatched event.
In this example, PingEvent is a subclass of
Event and therefore implements its own version of
clone().
Returns:
A new Event object that is identical to the original.
formatToString (className:String, ?p1:Dynamic, ?p2:Dynamic, ?p3:Dynamic, ?p4:Dynamic, ?p5:Dynamic):String
Checks whether the preventDefault() method has been called on
the event. If the preventDefault() method has been called,
returns true; otherwise, returns false.
Returns:
If preventDefault() has been called, returns
true; otherwise, returns false.
Cancels an event's default behavior if that behavior can be canceled.
Many events have associated behaviors that are carried out by default. For example, if a user types a character into a text field, the default behavior is that the character is displayed in the text field. Because the TextEvent.TEXT_INPUT event's default behavior can be canceled, you can use the preventDefault() method to prevent the character from appearing.
An example of a behavior that is not cancelable is the default behavior associated with the Event.REMOVED event, which is generated whenever Flash Player is about to remove a display object from the display list. The default behavior (removing the element) cannot be canceled, so the preventDefault() method has no effect on this default behavior.
You can use the Event.cancelable property to check whether you can prevent the default behavior associated with a particular event. If the value of Event.cancelable is true, then preventDefault() can be used to cancel the event; otherwise, preventDefault() has no effect.
stopImmediatePropagation ():Void
Prevents processing of any event listeners in the current node and any
subsequent nodes in the event flow. This method takes effect immediately,
and it affects event listeners in the current node. In contrast, the
stopPropagation() method doesn't take effect until all the
event listeners in the current node finish processing.
Note: This method does not cancel the behavior associated with
this event; see preventDefault() for that functionality.
Prevents processing of any event listeners in nodes subsequent to the
current node in the event flow. This method does not affect any event
listeners in the current node(currentTarget). In contrast,
the stopImmediatePropagation() method prevents processing of
event listeners in both the current node and subsequent nodes. Additional
calls to this method have no effect. This method can be called in any
phase of the event flow.
Note: This method does not cancel the behavior associated with
this event; see preventDefault() for that functionality.
