Tween in Flex
Tweeneris a Class used to create tweenings and other transitions via ActionScript code for projects built on the Flash platform. It's released and maintained for both ActionScript 2.0 (including Flash Lite 2.0) and ActionScript 3.0.
The general idea of a tweening Class is that dynamic animation and transitions (created by code) are easier to maintain and control, and more stable than animation based on the regular Flash timeline, since you can control it by time rather than by frames.
