name | proprietà |
public var name:String| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The name of the property to change. You must set this property, either in the SetProperty constructor or by setting the property value directly.
target | proprietà |
public var target:Object| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
The object containing the property to be changed.
If the property value is null, Flex uses the
immediate parent of the State object.
Il valore predefinito è null.

valueFactory | proprietà |
valueFactory:IDeferredInstance [sola scrittura] | Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |

Il valore predefinito è undefined.

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.
