| Versión de producto: | Flex 4 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Adds a visual element to this container.
The element is added after all other elements
and appears top of all other elements.
To add a visual element to a specific index position, use
the addElementAt() method.
If you add a visual element that already has a different container as a parent, the element is removed from the other container.
Parámetros
element:IVisualElement — The visual element to add as a child of this container.
|
IVisualElement — The element that was added.
|
Eventos
elementAdd: — Dispatched when
the element is added to the child list.
|
Emite
ArgumentError — If the element is the same as the visual container.

Adds a visual element to this container. The element is added at the index position specified. An index of 0 represents the first element in the display list.
If you add a visual element that already has a different container as a parent, the element is removed from the other container.
Parámetros
element:IVisualElement — The element to add as a child of this visual container.

index:int — The index position to which the element is added. If
you specify a currently occupied index position, the child
that exists at that position and all higher positions are moved
up one position in the child list.

| Versión de producto: | Flex 4 |
| Versiones de motor de ejecución: | Flash Player 10, AIR 1.5 |
Changes the position of an existing visual element in the visual container.
When you call the setElementIndex() method and specify an
index position that is already occupied, the only positions
that change are those in between the elements's former and new position.
All others stay the same.
If a visual element is moved to an index lower than its current index, the index of all elements in between increases by 1. If an element is moved to an index higher than its current index, the index of all elements in between decreases by 1.
Parámetros
element:IVisualElement — The element for which you want to change the index number.
| |
index:int — The resulting index number for the element.
|
Emite
RangeError — If the index does not exist in the child list.
