apply

()

method

override public function apply(parent:UIComponent):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Applies the override. Flex retains the original value, so that it can restore the value later in the remove() method.

This method is called automatically when the state is entered. It should not be called directly.

Parameters

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.

remove

()

method

override public function remove(parent:UIComponent):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Removes the override. The value remembered in the apply() method is restored.

This method is called automatically when the state is entered. It should not be called directly.

Parameters

parent:UIComponent — The parent of the state object containing this override. The override should use this as its target if an explicit target was not specified.
