You use an AddChildAction effect within a transition definition
to control when the view state change defined by an AddChild property
occurs during the transition.

"firstChild", "lastChild", and "index",
where "index" specifies to use the index property
to determine the position of the child.
De standaardwaarde is "index".
relativeTo | eigenschap |
public var relativeTo:DisplayObjectContainer| Taalversie: | ActionScript 3.0 |
| Productversie: | Flex 3 |
| Runtimeversies: | Flash Player 9, AIR 1.1 |
The location where the child component is added.
