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


Starting with Flex 4.0, Apache recommends that you use the spark.effects.Wipe class as an alternative to this class.

The direction-specific Wipe effects in Flex 3 have been replaced by a more generic Wipe effect that takes a generic direction. To get similar behavior from the new Wipe effect, set the direction parameter appropriately.


The WipeLeft class defines a wipe left effect. The before or after state of the component must be invisible.

You often use this effect with the showEffect and hideEffect triggers. The showEffect trigger occurs when a component becomes visible by changing its visible property from false to true. The hideEffect trigger occurs when the component becomes invisible by changing its visible property from true to false.

This effect inherits the MaskEffect.show property. If you set the value to true, the component appears. If you set the value to false, the component disappears. The default value is true.

If you specify this effect for a showEffect or hideEffect trigger, Flex sets the show property for you, either to true if the component becomes invisible, or false if the component becomes visible.
