Constant Detail

RESIZE

Constant
public static const RESIZE:String = "resize"

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The ResizeEvent.RESIZE constant defines the value of the type property of the event object for a resize 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.
oldHeightThe previous height of the object, in pixels.
oldWidthThe previous width of the object, in pixels.
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.
