interface IDataSelector<T>

The index of the currently selected item in the item collection. Returns -1 if no item is selected.

The following example selects an item by passing its index to the selectedIndex property:

The following example listens for when the selection of a ListView component changes, and it requests the new selected index:

var listView = new ListView();

{
	var listView = cast(event.currentTarget, ListView);
	trace("selection change: " + listView.selectedIndex);
}
listView.addEventListener(Event.CHANGE, changeHandler);
