newIndex

egenskap

public var newIndex:Number

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

The zero-based index after the change. For change events it is the index of the current child. For childIndexChange events, it is the new index of the child. For headerShift events, it is the new index of the header.

oldIndex

egenskap

public var oldIndex:Number

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

The zero-based index before the change. For change events it is the index of the previous child. For childIndexChange events, it is the previous index of the child. For headerShift events, it is the previous index of the header.

relatedObject

egenskap

public var relatedObject:DisplayObject

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

Flash Player 9, AIR 1.1

The child object whose index changed, or the object associated with the new index. This property is not set for header changes.

triggerEvent

egenskap

public var triggerEvent:Event

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

The IndexChangedEvent.CHANGE constant defines the value of the type property of the event object for a change event, which indicates that an index has changed, such as when and Accordion control changes the displayed panel or a ViewStack changes views.

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`.
`inputType`	Indicates whether this event was caused by a mouse or keyboard interaction.
`newIndex`	The zero-based index after the change.
`oldIndex`	The zero-based index before the change.
`relatedObject`	Contains a reference to the child object that corresponds to the new index.
`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`	The event that triggered this event.
`Type`	IndexChangedEvent.CHANGE
