Property Detail

disableLayout

property

disableLayout:Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

If true, the effect disables layout on its targets' parent containers, setting the containers autoLayout property to false, and also disables any layout constraints on the target objects. These properties are restored when the effect finishes.

The default value is false.

Implementation
public function get disableLayout():Boolean
public function set disableLayout(value:Boolean):void

easer

property

easer:IEaser

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The easing behavior for this effect. This IEaser object is used to convert the elapsed fraction of the animation into an eased fraction, which is then used to calculate the value at that eased elapsed fraction.

Note that it is possible to have easing at both the effect level and the Keyframe level (where Keyframes hold the values/times used in the MotionPath structures). These easing behaviors build on each other. The easer controls the easing of the overall effect. The Keyframe controls the easing in any particular interval of the animation. By default, the easing for Animate is non-linear (Sine(.5)). The easing for Keyframes is linear. If you desire an effect with easing at the keyframe level instead, you can set the easing of the effect to linear, and then set the easing specifically on the Keyframes.

The default value is spark.effects.easing.Sine(.5).

Implementation
public function get easer():IEaser
public function set easer(value:IEaser):void

spark.effects.easing.Sine

interpolator

property

interpolator:IInterpolator

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The interpolator used by this effect to calculate values between the start and end values of a property. By default, the NumberInterpolator class handles interpolation or, in the case of the start and end values being Arrays or Vectors, by the MultiValueInterpolator class. Interpolation of other types, or of Numbers that should be interpolated differently, such as uint values that hold color channel information, can be handled by supplying a different interpolator.

Implementation
public function get interpolator():IInterpolator
public function set interpolator(value:IInterpolator):void

motionPaths

property

motionPaths:Vector.<MotionPath>

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

A Vector of MotionPath objects, each of which holds the name of a property being animated and the values that the property takes during the animation. This Vector takes precedence over any properties declared in subclasses of Animate. For example, if this Array is set directly on a Move effect, then any properties of the Move effect, such as xFrom, are ignored.

Implementation
public function get motionPaths():Vector.<MotionPath>
public function set motionPaths(value:Vector.<MotionPath>):void

repeatBehavior

property

repeatBehavior:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The behavior of a repeating effect, which means an effect with repeatCount equal to either 0 or > 1. This value should be either RepeatBehavior.LOOP, which means the animation repeats in the same order each time, or RepeatBehavior.REVERSE, which means the animation reverses direction on each iteration.

The default value is RepeatBehavior.LOOP.

Implementation
public function get repeatBehavior():String
public function set repeatBehavior(value:String):void

()

Constructor

public function Animate(target:Object = null)

Language Version:

Event Detail

effectRepeat

Event

Event Object Type: mx.events.EffectEvent
property EffectEvent.type = mx.events.EffectEvent.EFFECT_REPEAT

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Dispatched when the effect begins a new repetition, for any effect that is repeated more than once. Flex also dispatches an effectUpdate event for the effect at the same time.

The EffectEvent.EFFECT_REPEAT constant defines the value of the type property of the event object for an effectRepeat event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`effectInstance`	The effect instance object for the event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

effectUpdate

Event

Event Object Type: mx.events.EffectEvent
property EffectEvent.type = mx.events.EffectEvent.EFFECT_UPDATE

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

Dispatched every time the effect updates the target.

The EffectEvent.EFFECT_UPDATE constant defines the value of the type property of the event object for an effectUpdate event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`effectInstance`	The effect instance object for the event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
