Descrizione della funzione di costruzione

()

Funzione di costruzione

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

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Constructor.

Parametri

	`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.

Descrizione dei metodi

apply

()

metodo

override public function apply(parent:UIComponent):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

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.

Parametri

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

()

metodo

override public function remove(parent:UIComponent):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

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.
