WipeLeft

Package | mx.effects
Class | public class WipeLeft
Inheritance | WipeLeft MaskEffect Effect flash.events.EventDispatcher

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 The direction-specific Wipe effects in Flex 3 have been replaced by a more generic Wipe effect that takes a generic direction.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.

The `<mx:WipeLeft>` tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

      <mx:WipeLeft
