className | property |
className:String
[read-only] Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The name of the effect class, such as "Fade"
.
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.
Implementation
public function get className():String
customFilter | property |
customFilter:mx.effects:EffectTargetFilter
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies a custom filter object, of type EffectTargetFilter, used by the effect to determine the targets on which to play the effect.
Target filtering is only performed if you call the
captureStartValues()
method before playing the effect.
Flex automatically calls the captureStartValues()
method
when the effect is part of a transition.
Use the filter
property for simple filtering.
If the customFilter
property is non-null,
the filter
property is ignored.
The default value is null.

duration | property |
duration:Number
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Duration of the effect in milliseconds.
In a Parallel or Sequence effect, the duration
property sets the duration of each effect.
For example, if a Sequence effect has its duration
property set to 3000, each effect in the Sequence takes 3000 ms
to play.
For a repeated effect, the duration
property
specifies the duration of a single instance of the effect.
Therefore, if an effect has a duration
property
set to 2000, and a repeatCount
property set to 3,
the effect takes a total of 6000 ms (6 seconds) to play.
The default value is 500.
Implementation
public function get duration():Number
public function set duration(value:Number):void
effectTargetHost | property |
effectTargetHost:mx.effects:IEffectTargetHost
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | 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.
Implementation
public function get effectTargetHost():mx.effects:IEffectTargetHost
public function set effectTargetHost(value:mx.effects:IEffectTargetHost):void
filter | property |
filter:String
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies an algorithm for filtering targets for an effect.
A value of null
specifies no filtering.
Target filtering is only performed if you call the
captureStartValues()
method before playing the effect.
Flex automatically calls the captureStartValues()
method
when the effect is part of a transition, or part of a data effect
for a list-based control.
Use this property for simple filtering.
Use the customFilter
property for more complex filtering.
If the customFilter
property has a non-null value,
this property is ignored.
You can use the following values for the filter
property:
- A value of
"add"
plays the effect on any targets that are added as a child to a container. - A value of
"addItem"
plays the effect on the item renderer for any list items added to a List or TileList control. - A value of
"hide"
plays the effect on any targets whose visible property changed fromtrue
tofalse
. - A value of
"move"
plays the effect on any targets that changed theirx
ory
properties. - A value of
"remove"
plays the effect on any targets that are removed as a child of a container. - A value of
"removeItem"
plays the effect on the item renderer for any list items removed from a List or TileList control. - A value of
"replacedItem"
plays the effect on the item renderer for any list items replaced in a List or TileList control by a new item. - A value of
"replacementItem"

hideFocusRing:Boolean
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | 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, 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
.
Implementation
public function get hideFocusRing():Boolean

targets | property |
targets:Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
An Array of objects that are targets for the effect.
When the effect is playing, it performs the effect on each target
in parallel.
Setting the target
property replaces all objects
in this Array.
When the targets
property is set, the target
property returns the first item in this Array.
Implementation
public function get targets():Array
public function set targets(value:Array):void
triggerEvent | property |
triggerEvent:Event
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |

captureEndValues | () | method |
public function captureEndValues():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Captures the current values of the relevant properties on the effect's targets and saves them as end values.
Flex automatically calls the captureEndValues()
method
when the effect is part of a data change effect.
captureMoreStartValues | () | method |
public function captureMoreStartValues(targets:Array):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Captures the current values of the relevant properties of an additional set of targets
Flex uses this function when a data change effect is run.
Parameters
targets:Array — Array of targets for which values are captured
|
captureStartValues | () | method |
public function captureStartValues():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Captures the current values of the relevant properties
on the effect's targets.
Flex automatically calls the captureStartValues()
method when the effect is part of a transition.
Use this function when you want the effect to figure out the start and end values of the effect. The proper usage of this function is to use it in the following steps:
- Call the
captureStartValues()
method. The effect captures the starting effect values. - Make changes to your effect targets, such as adding/removing children, altering properties, changing location, or changing dimensions.
- Call the
play()
method. The effect captures the end values. This function populates theEffectInstance.propertyChanges
property for each effect instance created by this effect. Effect developers can use thepropertyChanges
property to retrieve the start and end values for their effect.
createInstance | () | method |
public function createInstance(target:Object = null):IEffectInstance
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Creates a single effect instance and initializes it.
Use this method instead of the play()
method
to manipulate the effect instance properties
before the effect instance plays.
The effect instance is created with the type
specified in the instanceClass
property.
It is then initialized using the initInstance()
method.
If the instance was created by the EffectManager
(when the effect is triggered by an effect trigger),
the effect is further initialized by a call to the
EffectInstance.initEffect()
method.
Calling the createInstance()
method
does not play the effect.
Call the startEffect()
method
on the returned effect instance.
This function is automatically called by the
Effect.play()
method.
Parameters
target:Object (default = null ) — Object to animate with this effect.
|
IEffectInstance — The effect instance object for the effect.
|
createInstances | () | method |
public function createInstances(targets:Array = null):Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Takes an Array of target objects and invokes the
createInstance()
method on each target.
Parameters
targets:Array (default = null ) — Array of objects to animate with this effect.
|
Array — Array of effect instance objects, one per target,
for the effect.
|
deleteInstance | () | method |
public function deleteInstance(instance:IEffectInstance):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Removes event listeners from an instance and removes it from the list of instances.
Parameters
instance:IEffectInstance — The effect instance.
|
end | () | method |
public function end(effectInstance:IEffectInstance = null):void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Interrupts an effect that is currently playing,
and jumps immediately to the end of the effect.
Calling this method invokes the EffectInstance.end()
method.
The effect instance dispatches an effectEnd
event
when you call this method as part of ending the effect.
If you pass an effect instance as an argument, just that instance is interrupted. If no argument is passed in, all effect instances currently spawned from the effect are interrupted.
Parameters
effectInstance:IEffectInstance (default = null ) — EffectInstance to terminate.

getAffectedProperties | () | method |
public function getAffectedProperties():Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns an Array of Strings, where each String is the name
of a property changed by this effect.
For example, the Move effect returns an Array that contains
"x"
and "y"
.
Every subclass of Effect must implement this method. The EffectManager uses this method to ensure that no two effects are trying to animate the same property of the same object at the same time.
ReturnsArray — An Array of Strings specifying the names of the
properties modified by this effect.
|
pause | () | method |
public function pause():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Pauses the effect until you call the resume()
method.
play | () | method |
public function play(targets:Array = null, playReversedFromEnd:Boolean = false):Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Begins playing the effect.
You typically call the end()
method
before you call the play()
method
to ensure that any previous instance of the effect
has ended before you start a new one.
All subclasses must implement this method.
Parameters
targets:Array (default = null ) — Array of target objects on which to play this effect.
If this parameter is specified, then the effect's targets
property is not used.
| |
playReversedFromEnd:Boolean (default = false ) — If true ,
play the effect backwards.
|
Array — Array of EffectInstance objects, one per target,
for the effect.
|
resume | () | method |
public function resume():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Resumes the effect after it has been paused
by a call to the pause()
method.
reverse | () | method |
public function reverse():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Plays the effect in reverse, if the effect is currently playing, starting from the current position of the effect.
stop | () | method |
public function stop():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Stops the effect, leaving the effect targets in their current state.
Unlike a call to the pause()
method,
you cannot call the resume()
method after calling
the stop()
method.
However, you can call the play()
method to restart the effect.
The effect instance dispatches an effectEnd
event
when you call this method as part of ending the effect.
For mask effects, the mask is not removed automatically when the effect is stopped. Running further mask effects on the same target(s) without first removing the mask can produce unexpected results.
