The properties of the Event class carry basic information about an event, such as the event's type or whether the event's default behavior can be canceled. For many events, such as the events represented by the Event class constants, this basic information is sufficient. Other events, however, may require more detailed information. Events associated with a mouse click, for example, need to include additional information about the location of the click event and whether any keys were pressed during the click event. You can pass such additional information to event listeners by extending the Event class, which is what the MouseEvent class does. ActionScript 3.0 API defines several Event subclasses for common events that require additional information. Events associated with each of the Event subclasses are described in the documentation for each class.
The methods of the Event class can be used in event listener functions to affect the
behavior of the event object. Some events have an associated default behavior. For example,
the doubleClick event has an associated default behavior that highlights
the word under the mouse pointer at the time of the event.
Your event listener can cancel this
behavior by calling the preventDefault() method.
You can also make the current
event listener the last one to process an event by calling the stopPropagation()
or stopImmediatePropagation() method.
Other sources of information include:
- A useful description about the timing of events, code execution, and rendering at runtime in Ted Patrick's blog entry: Flash Player Mental Model - The Elastic Racetrack.
- A blog entry by Johannes Tacskovics about the timing of frame events, such as ENTER_FRAME, EXIT_FRAME: The MovieClip Lifecycle.

bubbles | property |
bubbles:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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.
Implementation
public function get bubbles():Booleancancelable | property |
cancelable:Boolean [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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.

public function get cancelable():BooleanRelated API Elements
currentTarget | property |
currentTarget:Object [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |

Implementation
public function get currentTarget():ObjectLearn more
eventPhase | property |
eventPhase:uint [read-only] | Language Version: | ActionScript 3.0 |

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).
Implementation
public function get eventPhase():uinttarget | property |
target:Object [read-only] | Language Version: | ActionScript 3.0 |

Event | () | Constructor |
public function Event(type:String, bubbles:Boolean = false, cancelable:Boolean = false)| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Creates an Event object to pass as a parameter to event listeners.
Parameterstype:String — The type of the event, accessible as Event.type.
| |
bubbles:Boolean (default = false)false.
| |
cancelable:Boolean (default = false)false.
|
clone | () | method |
public function clone():Event| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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().
class PingEvent extends Event {
var URL:String;
public override function clone():Event {
return new PingEvent(type, bubbles, cancelable, URL);
}
}
Event — A new Event object that is identical to the original.

formatToString | () | method |
public function formatToString(className:String, ... arguments):String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
A utility function for implementing the toString() method in custom
ActionScript 3.0 Event classes. Overriding the
toString() method is recommended, but not required.
class PingEvent extends Event {
var URL:String;
public override function toString():String {
return formatToString("PingEvent", "type", "bubbles", "cancelable", "eventPhase", "URL");
}
}
Parameters
className:String — The name of your custom Event class. In the previous example,
the className parameter is PingEvent.
| |
... arguments — The properties of the Event class and the
properties that you add in your custom Event class. In the previous example, the ...arguments
parameter includes type, bubbles, cancelable,
eventPhase, and URL.
|
String — The name of your custom Event class and the String value of your ...arguments
parameter.

isDefaultPrevented | () | method |
public function isDefaultPrevented():Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
Checks whether the preventDefault() method has been called on the event. If the
preventDefault() method has been called,
returns true; otherwise, returns false.
Boolean — If preventDefault() has been called, returns true; otherwise,
returns false.
|
Related API Elements
preventDefault | () | method |
public function preventDefault():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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 | () | method |
public function stopImmediatePropagation():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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.
Related API Elements
stopPropagation | () | method |
public function stopPropagation():void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 1.0, Flash Player 9, Flash Lite 4 |
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.

ADDED and ADDED_TO_STAGE events,
as well as the difference between REMOVED and REMOVED_FROM_STAGE
events. Clicking a sprite will remove it from the stage as well as everything nested within it.
For example, clicking the largest sprite will cause a REMOVED event
as well as three REMOVED_FROM_STAGE events to fire.
