Property Detail
targetproperty
public var target:DisplayObject

The child to remove from the view.

Constructor Detail
RemoveChild()Constructor
public function RemoveChild(target:DisplayObject = null)

Constructor.

Parameters
target:DisplayObject (default = null) — The child to remove from the view.
Method Detail
apply()method
public function apply(parent:UIComponent):void

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.

initialize()method 
public function initialize():void

Initializes the override. Flex calls this method before the first call to the apply() method, so you put one-time initialization code for the override in this method.

Flex calls this method automatically when the state is entered. It should not be called directly.

IOverride interface method; this class implements it as an empty method.

remove()method 
public function remove(parent:UIComponent):void

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.
