# ZoomViewTransition - AS3 Flex

Package | spark.transitions
Class | public class ZoomViewTransition
Inheritance | ZoomViewTransition ViewTransitionBase EventDispatcher Object

Deprecated since 4.6

Language Version: | ActionScript 3.0

Product Version: | Flex 4.5

Runtime Versions: | AIR 2.5

The ZoomViewTransition class performs a zoom in or out transition for views. It performs its transition by zooming out the existing view to reveal the new view, or by zooming in the new view to cover the existing view.

The default duration of a ZoomViewTransition is 350ms. Also, by default it transitions the control bar and view content as one as if `transitionControlsWithContent` is `true`.

Note:Create and configure view transitions in ActionScript; you cannot create them in MXML.
