className | 屬性 |
className:String [唯讀] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The name of the effect class, such as "FadeInstance".
This is a short or "unqualified" class name
that does not include the package name.
If you need the qualified name, use the
getQualifiedClassName() method
in the flash.utils package.

effectTargetHost | 屬性 |
effectTargetHost:mx.effects:IEffectTargetHost| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
A property that lets you access the target list-based control of a data effect. This property enables an instance of an effect class to communicate with the list-based control on which the effect is playing.
實作
public function get effectTargetHost():mx.effects:IEffectTargetHost public function set effectTargetHost(value:mx.effects:IEffectTargetHost):voidhideFocusRing | 屬性 |
hideFocusRing:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Determines whether the effect should hide the focus ring when starting the effect. The effect target is responsible for the hiding the focus ring. Subclasses of the UIComponent class hide the focus ring automatically. If the effect target is not a subclass of the UIComponent class, you must add functionality to it to hide the focus ring.
Set this property to true
to hide the focus ring during the effect.
For subclasses of Effect, the default value is false.
For subclasses of MaskEffect, the default value is true.
實作
public function get hideFocusRing():Boolean public function set hideFocusRing(value:Boolean):voidplayCount | 屬性 |
protected var playCount:int = 0| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Number of times that the instance has been played.
playheadTime | 屬性 |
playheadTime:Number| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Current time position of the effect.
This property has a value between 0 and the total duration,
which includes the Effect's startDelay,
repeatCount, and repeatDelay.
實作
public function get playheadTime():Number public function set playheadTime(value:Number):voidpropertyChanges | 屬性 |
propertyChanges:PropertyChanges| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Specifies the PropertyChanges object containing
the start and end values for the set of properties
relevant to the effect's targets.
This property is only set if the
captureStartValues() method was called
on the effect that created this effect instance.
You often use the propertyChanges property
to create an effect that is used as part of a transition.
Flex automatically calls the captureStartValues()
method when it starts a transition.
Within your override of the Effectinstance.play()
method, you can examine the information within the
propertyChanges() method to initialize
the start and end values of the effect.

repeatCount | 屬性 |
repeatDelay | 屬性 |
startDelay | 屬性 |
startDelay:int| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Amount of time, in milliseconds,
to wait before starting the effect.
Possible values are any int greater than or equal to 0.
If the effect is repeated by using the repeatCount
property, the startDelay property is applied
only the first time the effect is played.

suspendBackgroundProcessing:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
If true, blocks all background processing
while the effect is playing.
Background processing includes measurement, layout,
and processing responses that have arrived from the server.
實作

triggerEvent | 屬性 |
triggerEvent:Event| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The event, if any, which triggered the playing of the effect. This property is useful when an effect is assigned to multiple triggering events.
If the effect was played programmatically by a call to the
play() method, rather than being triggered by an event,
this property is null.
實作
public function get triggerEvent():Event public function set triggerEvent(value:Event):voidEffectInstance | () | 建構函式 |
end | () | 方法 |
public function end():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Interrupts an effect instance that is currently playing,
and jumps immediately to the end of the effect.
This method is invoked by a call
to the Effect.end() method.
As part of its implementation, it calls
the finishEffect() method.
The effect instance dispatches an effectEnd event
when you call this method as part of ending the effect.
In a subclass of EffectInstance,
you can optionally override this method
As part of your override, you should call
the super.end() method
from the end of your override, after your logic.

finishEffect | () | 方法 |
public function finishEffect():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Called by the end() method when the effect
finishes playing.
This function dispatches an endEffect event
for the effect target.
You do not have to override this method in a subclass. You do not need to call this method when using effects, but you may need to call it if you create an effect subclass.
finishRepeat | () | 方法 |
public function finishRepeat():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Called after each iteration of a repeated effect finishes playing.
You do not have to override this method in a subclass. You do not need to call this method when using effects.
initEffect | () | 方法 |
public function initEffect(event:Event):void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
This method is called if the effect was triggered by the EffectManager.
This base class version saves the event that triggered the effect
in the triggerEvent property.
Each subclass should override this method.
參數
event:Event — The Event object that was dispatched
to trigger the effect.
For example, if the trigger was a mouseDownEffect, the event
would be a MouseEvent with type equal to MouseEvent.MOUSEDOWN.
|
pause | () | 方法 |
public function pause():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Pauses the effect until you call the resume() method.
play | () | 方法 |
public function play():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Plays the effect instance on the target.
Call the startEffect() method instead
to make an effect start playing on an EffectInstance.
In a subclass of EffectInstance, you must override this method.
The override must call the super.play() method
so that an effectStart event is dispatched
from the target.

resume | () | 方法 |
public function resume():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Resumes the effect after it has been paused
by a call to the pause() method.
reverse | () | 方法 |
public function reverse():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Plays the effect in reverse, starting from the current position of the effect.
startEffect | () | 方法 |
public function startEffect():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Plays the effect instance on the target after the
startDelay period has elapsed.
Called by the Effect class.
Use this function instead of the play() method
when starting an EffectInstance.
stop | () | 方法 |
public function stop():void| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Stops the effect, leaving the target in its current state.
This method is invoked by a call
to the Effect.stop() method.
As part of its implementation, it calls
the finishEffect() method.
The effect instance dispatches an effectEnd event
when you call this method as part of ending the effect.
