The WipeLeft class defines a bar 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    id=”ID”  />
