The FadeInstance class implements the instance class for the Fade effect. Flex creates an instance of this class when it plays a Fade effect; you do not create one yourself.

Every effect class that is a subclass of the TweenEffect class supports the following events:

tweenEnd: Dispatched when the tween effect ends.
tweenUpdate: Dispatched every time a TweenEffect class calculates a new value.

The event object passed to the event listener for these events is of type TweenEvent. The TweenEvent class defines the property value, which contains the tween value calculated by the effect. For the Fade effect, the TweenEvent.value property contains a Number between the values of the Fade.alphaFrom and Fade.alphaTo properties.
