The IndexChangedEvent class represents events that are dispatched when
an index changes.
This event can indicate that the index value of a child of a container changed,
the displayed child of a navigator container such as an Accordion or
ViewStack changed, or the order of column headers in a DataGrid
control changed.
public var newIndex:Number
Language Version : | ActionScript 3.0 |
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.
public var oldIndex:Number
Language Version : | ActionScript 3.0 |
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.
public var relatedObject:DisplayObject
Language Version : | ActionScript 3.0 |
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.
public var triggerEvent:Event
Language Version : | ActionScript 3.0 |
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.
public function IndexChangedEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, relatedObject:DisplayObject = null, oldIndex:Number = -1, newIndex:Number = -1, triggerEvent:Event = null)
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Constructor.
Normally called by a Flex control and not used in application code.
Parameters | type:String — The event type; indicates the action that caused the event.
|
|
| 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.
|
|
| relatedObject:DisplayObject (default = null ) — The child object associated with the index change.
|
|
| oldIndex:Number (default = -1 ) — The zero-based index before the change.
|
|
| newIndex:Number (default = -1 ) — The zero-based index after the change.
|
|
| triggerEvent:Event (default = null ) — The event that triggered this event.

public static const CHANGE:String = change
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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 |
public static const CHILD_INDEX_CHANGE:String = childIndexChange
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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.
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 of the
child after the change. |
oldIndex | The zero-based index of the
child before the change. |
relatedObject | Contains a reference
to the child object whose index changed. |
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 | null |
Type | IndexChangedEvent.CHILD_INDEX_CHANGE |
public static const HEADER_SHIFT:String = headerShift
Language Version : | ActionScript 3.0 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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.
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 of the
header after the change. |
oldIndex | The zero-based index of the
header before the change. |
relatedObject | null |
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.HEADER_SHIFT |
