className | property |
className:String
[read-only]
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.
public function get className():String
duration | property |
duration:Number
The duration of the effect, in milliseconds.
public function get duration():Number
public function set duration(value:Number):void
effect | property |
effect:IEffect
The IEffect object that created this IEffectInstance object.
public function get effect():IEffect
public function set effect(value:IEffect):void
effectTargetHost | property |
effectTargetHost:mx.effects:IEffectTargetHost
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.
public function get effectTargetHost():mx.effects:IEffectTargetHost
public function set effectTargetHost(value:mx.effects:IEffectTargetHost):void
hideFocusRing | property |
hideFocusRing:Boolean
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
.
public function get hideFocusRing():Boolean
public function set hideFocusRing(value:Boolean):void
playheadTime | property |
playheadTime:Number
[read-only]
Current position in time of the effect.
This property has a value between 0 and the actual duration
(which includes the value of the startDelay
,
repeatCount
, and repeatDelay
properties).
public function get playheadTime():Number
propertyChanges | property |
propertyChanges:PropertyChanges
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.
public function get propertyChanges():PropertyChanges
public function set propertyChanges(value:PropertyChanges):void
See also
repeatCount | property |
repeatCount:int
Number of times to repeat the effect. Possible values are any integer greater than or equal to 0.
public function get repeatCount():int
public function set repeatCount(value:int):void
repeatDelay | property |
repeatDelay:int
Amount of time, in milliseconds, to wait before repeating the effect.
public function get repeatDelay():int
public function set repeatDelay(value:int):void
startDelay | property |
startDelay:int
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.
public function get startDelay():int
public function set startDelay(value:int):void
suspendBackgroundProcessing | property |
suspendBackgroundProcessing:Boolean
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.
public function get suspendBackgroundProcessing():Boolean
public function set suspendBackgroundProcessing(value:Boolean):void
target | property |
target:Object
The UIComponent object to which this effect is applied.
public function get target():Object
public function set target(value:Object):void
triggerEvent | property |
triggerEvent:Event
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
.
public function get triggerEvent():Event
public function set triggerEvent(value:Event):void
EffectInstance | () | Constructor |
public function EffectInstance(target:Object)
Constructor.
Parameterstarget:Object — UIComponent object to animate with this effect.
|
end | () | method |
public function end():void
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.
See also
finishEffect | () | method |
public function finishEffect():void
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 | () | method |
public function finishRepeat():void
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 | () | method |
public function initEffect(event:Event):void
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.
Parameters
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 | () | method |
public function pause():void
Pauses the effect until you call the resume()
method.
play | () | method |
public function play():void
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.
See also
resume | () | method |
public function resume():void
Resumes the effect after it has been paused
by a call to the pause()
method.
reverse | () | method |
public function reverse():void
Plays the effect in reverse, starting from the current position of the effect.
startEffect | () | method |
public function startEffect():void
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 | () | method |
public function stop():void
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.
