| Constant | Defined By | ||
|---|---|---|---|
| CHANGE : String = "change" [static]
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. | IndexChangedEvent | ||
| CHILD_INDEX_CHANGE : String = "childIndexChange" [static]
The IndexChangedEvent.CHILD_INDEX_CHANGE constant defines the value of the
type property of the event object for a childIndexChange event,
which indicates that a component's index among a container's children
has changed. | IndexChangedEvent | ||
| HEADER_SHIFT : String = "headerShift" [static]
The IndexChangedEvent.HEADER_SHIFT constant defines the value of the
type property of the event object for a headerShift event,
which indicates that a header has changed its index, as when a user drags
a DataGrid column to a new position. | IndexChangedEvent | ||
newIndex | property |
public var newIndex:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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 | property |
public var oldIndex:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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 | property |
public var relatedObject:DisplayObject| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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 | property |
public var triggerEvent:Event| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The event that triggered this event.
Indicates whether this event was caused by a mouse or keyboard interaction.
The value is null when a container dispatches a
childIndexChanged event.

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

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. |
