常數詳細資訊
CLOSE | 常數 |
public static const CLOSE:String = "close"
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | Flash Player 10, AIR 1.5 |
The DropDownEvent.CLOSE
constant defines the value of the
type
property of the event object for a close
event.
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 . |
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. |
triggerEvent | A value indicating the type of input action that triggered the event. |
OPEN | 常數 |
public static const OPEN:String = "open"
語言版本: | ActionScript 3.0 |
產品版本: | Flex 4 |
執行階段版本: | Flash Player 10, AIR 1.5 |
The DropDownEvent.OPEN
constant defines the value of the
type
property of the event object for a open
event.
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 . |
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. |
triggerEvent | A value indicating the type of input action that triggered the event. |
