CARET_CHANGE : String = "caretChange" [statico]

type property of the event object for a caretChange event,
which indicates that the current item in focus is about to change. | IndexChangeEvent | ||
CHANGE : String = "change" [statico]
The IndexChangeEvent.CHANGE constant defines the value of the
type property of the event object for a change event,

changes its selection. | IndexChangeEvent | ||
CHANGING : String = "changing" [statico]

type property of the event object for a changing event,

public var newIndex:int
Versione linguaggio: | ActionScript 3.0 |

events
it is the index of the current child.

bubbles:Boolean (default = false ) — Specifies whether the event can bubble
up the display list hierarchy.

cancelable:Boolean (default = false ) — Specifies whether the behavior
associated with the event can be prevented.

CARET_CHANGE | Costante |
public static const CARET_CHANGE:String = "caretChange"
Versione linguaggio: | ActionScript 3.0 |
Versione prodotto: | Flex 4 |
Versioni runtime: | Flash Player 10, AIR 1.5 |
The IndexChangeEvent.CARET_CHANGE
constant defines the value of the
type
property of the event object for a caretChange
event,
which indicates that the current item in focus is about to change.
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 . |
newIndex | The zero-based index of the selected item after the change. |
oldIndex | The zero-based index of the selected item before the change. |
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. |

property of the event object for a changing
event,
which indicates that the current selection is about to change.
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
