| Inheritance | Resize  TweenEffect Effect EventDispatcher Object |
If you specify only two of the three values of the
widthFrom, widthTo, and
widthBy properties, Flex calculates the third.
If you specify all three, Flex ignores the widthBy value.
If you specify only the widthBy or the
widthTo value, the widthFrom property
is set to be the object's current width.
The same is true for heightFrom, heightTo,
and heightBy property values.
If you specify a Resize effect for a resize 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 size and its new size.

createInstance(target:Object = null):IEffectInstance

| Effect | |
|
Returns an Array of Strings, where each String is the name
of a property that is changed by this effect.
| Effect | |
|
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event.

pause():void
Pauses the effect until you call the
resume() method. | Effect | |
|
Begins playing the effect.
| Effect | |

reverse():void
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 | |
|
Returns the string representation of the specified object.

| heightBy | property |
public var heightBy:NumberNumber of pixels by which to modify the height of the component. Values may be negative.
| heightFrom | property |
public var heightFrom:NumberInitial height, in pixels. If omitted, Flex uses the current height.
| heightTo | property |
public var heightTo:NumberFinal height, in pixels.
| hideChildrenTargets | property |
public var hideChildrenTargets:ArrayAn Array of Panel containers. The children of these Panel containers are hidden while the Resize effect plays.
You use data binding syntax to set this property in MXML, as the following example shows, where panelOne and panelTwo are the names of two Panel containers in your application:
<mx:Resize id="e" heightFrom="100" heightTo="400"
hideChildrenTargets="{[panelOne, panelTwo]}" />
| widthBy | property |
public var widthBy:NumberNumber of pixels by which to modify the width of the component. Values may be negative.
| widthFrom | property |
public var widthFrom:NumberInitial width, in pixels. If omitted, Flex uses the current width.
| widthTo | property |
public var widthTo:NumberFinal width, in pixels.
| Resize | () | constructor |
public function Resize(target:Object = null)Constructor.
