Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Starting with Flex 4.0, Adobe recommends that you use the spark.effects.Fade class as an alternative to this class. |
The Fade effect animates the
alpha
property of a component,
either from transparent to opaque, or from opaque to transparent.
If you specify the Fade effect for the showEffect
or hideEffect
trigger, and if you omit values for the
alphaFrom
and alphaTo
properties,
the effect automatically transitions alpha
from 0
to the target's current alpha
value on a
showEffect
trigger, and from the target's current
alpha
value to 0 on a hideEffect
trigger.
Note: To use the Fade effect with text, you must use an embedded font, not a device font.

Constructor. | Fade | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | ||
Captures the current values of the relevant properties
on the effect's targets and saves them as end values. | Effect | ||
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.
| Effect | ||
Captures the current values of the relevant properties
on the effect's targets. | Effect | ||
Creates a single effect instance and initializes it. | Effect | ||
Takes an Array of target objects and invokes the
createInstance() method on each target. | Effect | ||
Removes event listeners from an instance
and removes it from the list of instances. | Effect | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Interrupts an effect that is currently playing,
and jumps immediately to the end of the effect. | Effect | ||
Returns an Array of Strings, where each String is the name
of a property changed by this effect. | Effect | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Pauses the effect until you call the resume() method. | Effect | ||
Begins playing the effect. | Effect | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Resumes the effect after it has been paused
by a call to the pause() method. | Effect | ||
Plays the effect in reverse, if the effect is currently playing,
starting from the current position of the effect. | Effect | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Stops the effect, leaving the effect targets in their current state. | Effect | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |

the default value is 0.0.
If the effect causes the target component to appear,
the default value is the current value of the target's
alpha
property.
