Property Detail

dragging

property

dragging:Boolean

Language Version :

ActionScript 3.0

Product Version :

Flex 4

Runtime Versions :

Flash Player 10, AIR 1.5

Contains true if the item renderer is being dragged.

Implementation
public function get dragging():Boolean
public function set dragging(value:Boolean):void

itemIndex

property

itemIndex:int

Language Version :

ActionScript 3.0

Product Version :

Flex 4

Runtime Versions :

Flash Player 10, AIR 1.5

The index of the item in the data provider of the host component of the item renderer.

Implementation
public function get itemIndex():int
public function set itemIndex(value:int):void

label

property

label:String

Language Version :

ActionScript 3.0

Product Version :

Flex 4

Runtime Versions :

Flash Player 10, AIR 1.5

The String to display in the item renderer.

The host component of the item renderer can use the itemToLabel() method to convert the data item to a String for display by the item renderer.

For controls like List and ButtonBar, you can use the labelField or labelFunction properties to specify the field of the data item that contains the String. Otherwise the host component uses the toString() method to convert the data item to a String.

Implementation
public function get label():String
public function set label(value:String):void

selected

property

selected:Boolean

Language Version :

ActionScript 3.0

Product Version :

Flex 4

Runtime Versions :

Flash Player 10, AIR 1.5

Contains true if the item renderer can show itself as selected.

Implementation
public function get selected():Boolean
public function set selected(value:Boolean):void

showsCaret

property

showsCaret:Boolean

Language Version :

ActionScript 3.0

Product Version :

Flex 4

Runtime Versions :

Flash Player 10, AIR 1.5

Contains true if the item renderer can show itself as focused.

Implementation
public function get showsCaret():Boolean
public function set showsCaret(value:Boolean):void
