Classpublic class PostScaleAdapter
InheritancePostScaleAdapter Inheritance Object
Implements IUIComponent, IConstraintClient, IInvalidating

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The PostScaleAdapter class is used as a compatibility layer for Flex 3 classes that rely on width, height, min, max, explicit, measured, and other properties to be determined after scaling is applied. This is useful since in Flex 4, the properties are calculated before scaling is applied.

Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Moves this object to the specified x and y coordinates.

Parameters

x:Number — The new x-position for this object.
 
y:Number — The new y-position for this object.

owns

()method 
public function owns(displayObject:DisplayObject):Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Parameters

displayObject:DisplayObject

Returns
Boolean

parentChanged

()method 
public function parentChanged(p:DisplayObjectContainer):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Parameters

p:DisplayObjectContainer

removeEventListener

()method 
public function removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void

Parameters

type:String
 
listener:Function
 
useCapture:Boolean (default = false)

setActualSize

()method 
public function setActualSize(newWidth:Number, newHeight:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sets the actual size of this object.

This method is mainly for use in implementing the updateDisplayList() method, which is where you compute this object's actual size based on its explicit size, parent-relative (percent) size, and measured size. You then apply this actual size to the object by calling setActualSize().

In other situations, you should be setting properties such as width, height, percentWidth, or percentHeight rather than calling this method.

Parameters

newWidth:Number — The new width for this object.
 
newHeight:Number — The new height for this object.

setConstraintValue

()method 
public function setConstraintValue(constraintName:String, value:*):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sets the specified constraint value.

Parameters

constraintName:String — name of the constraint value. Constraint parameters are "baseline", "bottom", "horizontalCenter", "left", "right", "top", and "verticalCenter".

For more information about these parameters, see the Canvas and Panel containers and Styles Metadata AnchorStyles.

 
value:* — The new value for the constraint.

setVisible

()method 
public function setVisible(value:Boolean, noEvent:Boolean = false):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Parameters

value:Boolean
 
noEvent:Boolean (default = false)

validateNow

()method 
public function validateNow():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Validates and updates the properties and layout of this object by immediately calling validateProperties(), validateSize(), and validateDisplayList(), if necessary.

When properties are changed, the new values do not usually have an immediate effect on the component. Usually, all of the application code that needs to be run at that time is executed. Then the LayoutManager starts calling the validateProperties(), validateSize(), and validateDisplayList() methods on components, based on their need to be validated and their depth in the hierarchy of display list objects.

For example, setting the width property is delayed, because it may require recalculating the widths of the object's children or its parent. Delaying the processing also prevents it from being repeated multiple times if the application code sets the width property more than once. This method lets you manually override this behavior.

willTrigger

()method 
public function willTrigger(type:String):Boolean

Parameters

type:String

Returns
Boolean
