常數詳細資訊
CURRENT_STATE_CHANGE | 常數 |
public static const CURRENT_STATE_CHANGE:String = "currentStateChange"| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | 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 | 常數 |
public static const CURRENT_STATE_CHANGING:String = "currentStateChanging"| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The StateChangeEvent.CURRENT_STATE_CHANGING constant defines the
value of the type property of the event that is dispatched
when the view state is about to change.
The value of this constant is "currentStateChanging".
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 is being entered. |
oldState | The name of the view state that is being 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. |
