public var name:String

Language Version: ActionScript 3.0

The name of the style to change. You must set this property, either in the SetStyle constructor or by setting the property value directly.

target

property 
public var target:Object

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

The object whose style is being changed. If the property value is null, Flex uses the immediate parent of the State object.

The default value is null.

value

property 
value:Object

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

The new value for the style.

The default value is undefined.



Implementation

    public function set value(value:Object):void

valueFactory

property 
valueFactory:IDeferredInstance  [write-only]

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 9, AIR 1.1

An optional write-only property from which to obtain a shared value. This is primarily used when this override's value is shared by multiple states or state groups.

The default value is undefined.

Constructor Detail

SetStyle

()Constructor
public function SetStyle(target:IStyleClient = null, name:String = null, value:Object = null, valueFactory:IDeferredInstance = null)

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

Constructor.

Parameters
target:IStyleClient (default = null) — The object whose style is being set. By default, Flex uses the immediate parent of the State object.
 
name:String (default = null) — The style to set.
 
value:Object (default = null) — The value of the style in the view state.
 
valueFactory:IDeferredInstance (default = null) — An optional write-only property from which to obtain a shared value. This is primarily used when this override's value is shared by multiple states or state groups.
Method Detail

apply

()method
override public function apply(parent:UIComponent):void

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

Applies the override. Flex retains the original value, so that it can restore the value later in the remove() method.

This method is called automatically when the state is entered. It should not be called directly.

Parameters

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.

remove

()method 
override public function remove(parent:UIComponent):void

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

Removes the override. The value remembered in the apply() method is restored.

This method is called automatically when the state is entered. It should not be called directly.

Parameters

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.
