Constant Detail
ELEMENT_ADD | Constant |
public static const ELEMENT_ADD:String = "elementAdd"| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
The ElementExistenceEvent.ELEMENT_ADD constant
defines the value of the type property of the event
object for an elementAdd 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. |
element | Contains a reference to the visual element that was added. |
index | The index where the visual element that was added. |
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. |

The ElementExistenceEvent.ELEMENT_REMOVE constant
defines the value of the type property of the event
object for an elementRemove 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. |
element | A reference to the visual element that is about to be removed. |
index | The index of visual element that is being removed. |
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
