The IItemRenderer interface defines the basic set of APIs that a class must implement to create an item renderer that can communicate with a host component. The host component, such as the List or ButtonBar controls, must implement the IItemRendererOwner interface.

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.

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