public static const CURRENT_STATE_CHANGE:String = "currentStateChange"| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
The StateChangeEvent.CURRENT_STATE_CHANGE constant defines the
value of the type property of the event that is dispatched
when the view state has changed.
The value of this constant is "currentStateChange".
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
newState | The name of the view state that was entered. |
oldState | The name of the view state that was exited. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
