<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();
Pokaż składnię MXML

<mx:tagname>
<mx:children>
<!-- Specify child effect tags -->
</mx:children>
