`public static const CURRENT_STATE_CHANGE:String = currentStateChange`

Language Version : | ActionScript 3.0

Product Version : | Flex 3

Runtime Versions : | 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.
`type` | StateChangeEvent.CURRENT_STATE_CHANGE

CURRENT_STATE_CHANGING | Constant |

`public static const CURRENT_STATE_CHANGING:String = currentStateChanging`
