<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>

Returns the duration of this effect as defined by the duration of all child effects. This takes into account the startDelay and repetition info for all child effects, along with their durations, and returns the appropriate result.

Adds a new child effect to this composite effect. A Sequence effect plays each child effect one at a time, in the order that they were added. A Parallel effect plays all child effects simultaneously; the order in which they are added does not matter.
參數
childEffect:IEffect — Child effect to be added
to the composite effect.
