You can create a Sequence effect in MXML, as the following example shows:
<mx:Sequence id="WipeRightUp"> <mx:children> <mx:WipeRight duration="1000"/> <mx:WipeUp duration="1000"/> </mx:children> </mx:Sequence> <mx:VBox id="myBox" hideEffect="{WipeRightUp}"> <mx:TextArea id="aTextArea" text="hello"/> </mx:VBox>
Notice that 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 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 Sequence effect's
play()
method; for example:mySequenceEffect.play();
The <mx:Sequence>
tag
inherits all of the tag attributes of its superclass,
and adds the following tag attributes:
<mx:Sequence id="identifier"> <mx:children> <!-- Specify child effect tags --> </mx:children> </mx:Sequence>
