Constant Detail
CHILD_ADD | Constant |
public static const CHILD_ADD:String = "childAdd"| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The ChildExistenceChangedEvent.CHILD_ADD constant
defines the value of the type property of the event
object for a childAdd 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. |
relatedObject | Contains a reference to the child object that was created. |
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. |
CHILD_REMOVE | Constant |
public static const CHILD_REMOVE:String = "childRemove"| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The ChildExistenceChangedEvent.CHILD_REMOVE constant
defines the value of the type property of the event
object for a childRemove 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. |
relatedObject | Contains a reference to the child object that is about to be 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
Object listening for the event. |
OVERLAY_CREATED | Constant |
public static const OVERLAY_CREATED:String = "overlayCreated"| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The ChildExistenceChangedEvent.OVERLAY_CREATED constant
defines the value of the type property of the event object
for a overlayCreated 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. |
relatedObject | Contains a reference to the child object whose overlay was created. |
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. |
