<mx:Parallel>
and <mx:Sequence>
MXML tags.
Flex supports two methods to combine, or composite, effects:
parallel and sequence.
When you combine multiple effects in parallel,
the effects play at the same time.
When you combine multiple effects in sequence,
one effect must complete before the next effect starts.
You can create a composite effect in MXML, as the following example shows:
<mx:Parallel id="WipeRightUp"> <mx:children> <mx:WipeRight duration="1000"/> <mx:WipeUp duration="1000"/> </mx:children> </mx:Parallel> <mx:VBox id="myBox" hideEffect="WipeRightUp"> <mx:TextArea id="aTextArea" text="hello"/> </mx:VBox>
The <mx:children>
tag is optional.
Starting a composite effect in ActionScript is usually a five-step process:
- Create instances of the effect objects to be composited together;
for example:
myFadeEffect = new mx.effects.Fade(target);
- Set properties, such as
duration
, on the individual effect objects. - Create an instance of the Parallel or Sequence effect object;
for example:
mySequenceEffect = new mx.effects.Sequence();
- Call the
addChild()
method for each of the effect objects; for example:mySequenceEffect.addChild(myFadeEffect);
- Invoke the composite effect's
play()
method; for example:mySequenceEffect.play();

The CompositeEffect class adds the following tag attributes, and all the subclasses of the CompositeEffect class inherit these tag attributes:
<mx:tagname> <mx:children> <!-- Specify child effect tags --> </mx:children> </mx:tagname>

![]() | addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | |
![]() |
Dispatches an event into the event flow. | EventDispatcher | |
![]() |
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | |
![]() |
Indicates whether an object has a specified property defined. | Object | |
![]() |
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | |
![]() |
Indicates whether the specified property exists and is enumerable. | Object | |
![]() |
Removes a listener from the EventDispatcher object. | EventDispatcher | |
![]() |
Sets the availability of a dynamic property for loop operations. | Object | |
![]() |
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | |
![]() |
Returns the string representation of the specified object. | Object | |
![]() |
Returns the primitive value of the specified object. | Object | |
![]() |
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |
