ListEvent

Package	spark.events
Class	public class ListEvent
Inheritance	ListEvent MouseEvent Event Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4.5

Runtime Versions:

Flash Player 10.2, AIR 2.5

ListEvents dispatched by ListBase components like ButtonBar and List in response to MouseEvents are constructed with the incoming mouse event's properties. The list event's x,y location, i.e. the value of its localX and localY properties, is defined relative to the entire component, not just the part of the component that has been scrolled into view. Similarly, the event's row and column indices may correspond to a cell that has not been scrolled into view.

Runtime Versions:

Flash Player 10.2, AIR 2.5

The ListEvent.ITEM_ROLL_OUT constant defines the value of the type property of the ListEvent object for an itemRollOut event, which indicates that the user rolled the mouse pointer out of a visual item in the control.

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`.
`itemIndex`	The data provider index of the item displayed by the item renderer where the event occurred.
`item`	The data provider item for the item renderer.
`itemRenderer`	The The item renderer that displayed this item.
`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.
`Type`	ListEvent.ITEM_ROLL_OUT

ITEM_ROLL_OVER

Constant

public static const ITEM_ROLL_OVER:String = "itemRollOver"

Language Version:

ActionScript 3.0

The ListEvent.ITEM_ROLL_OVER constant defines the value of the type property of the ListEvent object for an itemRollOver event, which indicates that the user rolled the mouse pointer over a visual item in the control.

The properties of the event object have the following values:

Property	Value
`bubbles`	false

`itemIndex`	The data provider index of the item displayed by the item renderer where the event occurred.
`item`	The data provider item for the item renderer.
`itemRenderer`	The The item renderer that displayed this item.
