Starting with Flex 4.0, Adobe recommends that you use the spark.effects.Move class as an alternative to this class. |
The Move effect changes the position of a component over a specified time interval. You can specify the initial position with the
xFrom
and
yFrom
values, the destination position with xTo
and yTo
, or the number of pixels to move the component
with xBy
and yBy
.
If you specify any two of the values (initial position, destination,
or amount to move), Flex calculates the third.
If you specify all three, Flex ignores the xBy
and
yBy
values.
If you specify only the xTo
and yTo
values
or the xBy
and yBy
values,
Flex sets xFrom
and yFrom
to be the object's
current position.
If you specify a Move effect for a moveEffect
trigger,
and if you do not set the six From, To, and By properties,
Flex sets them to create a smooth transition between the object's
old position and its new position.
You typically apply this effect to a target in a container
that uses absolute positioning, such as Canvas,
or one with "layout=absolute"
, such as Application or Panel.
If you apply it to a target in a container that performs automatic layout,
such as a VBox or Grid container,
the move occurs, but the next time the container updates its layout,
it moves the target back to its original position.
You can set the container's autoLayout
property to false
to disable the move back, but that disables layout for all controls in the container.
The <mx:Move>
tag
inherits all of the tag attributes of its of its superclass,
and adds the following tag attributes:
<mx:Move id="ID" xFrom="val" yFrom="val" xTo="val" yTo="val" xBy="val" yBy="val" />

---|---|---|---|
Constructor. | Move | ||
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 the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
