CLOSE

Constant
public static const CLOSE:String = "close"

Language Version: ActionScript 3.0
Product Version: Flex 4

The DropDownEvent.CLOSE constant defines the value of the type property of the event object for a close event.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
cancelablefalse
currentTargetThe 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.
targetThe 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.
triggerEventA value indicating the type of input action that triggered the event.
