are undefined, the component has a transparent background.
For the Application container, this style specifies the background color while the application loads, and a background gradient while it is running. Flex calculates the gradient pattern between a color slightly darker than the specified color, and a color slightly lighter than the specified color. The default skins of most Flex controls are partially transparent. As a result, the background color of
a container partially "bleeds through" to controls that are in that container. You can avoid this by setting the

During initialization, the child descriptors are used to create the container's child UIComponent objects and its Repeater objects, and to give them the initial property values, event handlers, effects, and so on, that were specified in MXML.

The child creation policy for this MX Container.
ActionScript values can be ContainerCreationPolicy.AUTO,
ContainerCreationPolicy.ALL,
or ContainerCreationPolicy.NONE.
MXML values can be auto, all,
or none.
If no creationPolicy is specified for a container,
that container inherits its parent's creationPolicy.
If no creationPolicy is specified for the Application,
it defaults to ContainerCreationPolicy.AUTO.
A creationPolicy of ContainerCreationPolicy.AUTO means
that the container delays creating some or all descendants
until they are needed, a process which is known as deferred
instantiation.
This policy produces the best startup time because fewer
UIComponents are created initially.
However, this introduces navigation delays when a user navigates
to other parts of the application for the first time.
Navigator containers such as Accordion, TabNavigator, and ViewStack
implement the ContainerCreationPolicy.AUTO policy by creating all their
children immediately, but wait to create the deeper descendants
of a child until it becomes the selected child of the navigator
container.
A creationPolicy of ContainerCreationPolicy.ALL means
that the navigator containers immediately create deeper descendants
for each child, rather than waiting until that child is
selected. For single-view containers such as a VBox container,
there is no difference between the ContainerCreationPolicy.AUTO and
ContainerCreationPolicy.ALL policies.
A creationPolicy of ContainerCreationPolicy.NONE means
that the container creates none of its children.
In that case, it is the responsibility of the MXML author
to create the children by calling the
createComponentsFromDescriptors() method.
Il valore predefinito è ContainerCreationPolicy.AUTO.

rawChildren:IChildList [sola lettura] | Versione linguaggio: | ActionScript 3.0 |

A container typically contains child components, which can be enumerated
using the Container.getChildAt() method and
Container.numChildren property. In addition, the container
may contain style elements and skins, such as the border and background.
Flash Player and AIR do not draw any distinction between child components
and skins. They are all accessible using the player's
getChildAt() method and
numChildren property.
However, the Container class overrides the getChildAt() method
and numChildren property (and several other methods)
to create the illusion that
the container's children are the only child components.
If you need to access all of the children of the container (both the
content children and the skins), then use the methods and properties
on the rawChildren property instead of the regular Container methods.
For example, use the Container.rawChildren.getChildAt()) method.
However, if a container creates a ContentPane Sprite object for its children,
the rawChildren property value only counts the ContentPane, not the
container's children.
It is not always possible to determine when a container will have a ContentPane.
Note:If you call the addChild or
addChildAt method of the rawChildren object,
set tabFocusEnabled = false on the component that you have added.
Doing so prevents users from tabbing to the visual-only component
that you have added.

When you add a new child at an index that is already occupied by an old child, it doesn't replace the old child; instead the old child and the ones after it "slide over" and have their index incremented by one. For example, suppose a Container contains the children (A, B, C) and you add D at index 1. Then the container will contain (A, D, B, C).

Workaround for MXML container/bindings problem (177074): override Container.executeBindings() to prefer descriptor.document over parentDocument in the call to BindingManager.executeBindings(). This should always provide the correct behavior for instances created by descriptor, and will provide the original behavior for procedurally-created instances. (The bug may or may not appear in the latter case.) A more complete fix, guaranteeing correct behavior in both non-DI and reparented-component scenarios, is anticipated for updater 1.
Parametri
recurse:Boolean (default = false)false, then only execute the bindings
on this Container.
If true, then also execute the bindings on this
container's children, grandchildren,
great-grandchildren, and so on.

getChildAt | () | metodo |
override public function getChildAt(index:int):DisplayObject| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Gets the nth child component object.
The children returned from this method include children that are
declared in MXML and children that are added using the
addChild() or addChildAt() method.
Parametri
index:int — Number from 0 to (numChildren - 1).
|
DisplayObject — Reference to the child as an object of type DisplayObject.
You typically cast the return value to UIComponent,
or to the type of a specific Flex control, such as ComboBox or TextArea.
|
getChildByName | () | metodo |
override public function getChildByName(name:String):DisplayObject| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |

getChildIndex | () | metodo |
override public function getChildIndex(child:DisplayObject):int| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | Flash Player 9, AIR 1.1 |
Gets the zero-based index of a specific child.
The first child of the container (i.e.: the first child tag that appears in the MXML declaration) has an index of 0, the second child has an index of 1, and so on. The indexes of a container's children determine the order in which they get laid out. For example, in a VBox the child with index 0 is at the top, the child with index 1 is below it, etc.
If you add a child by calling the addChild() method,
the new child's index is equal to the largest index among existing
children plus one.
You can insert a child at a specified index by using the
addChildAt() method; in that case the indices of the
child previously at that index, and the children at higher indices,
all have their index increased by 1 so that all indices fall in the
range from 0 to (numChildren - 1).
If you remove a child by calling removeChild()
or removeChildAt() method, then the indices of the
remaining children are adjusted so that all indices fall in the
range from 0 to (numChildren - 1).
If myView.getChildIndex(myChild) returns 5,
then myView.getChildAt(5) returns myChild.
The index of a child may be changed by calling the
setChildIndex() method.
Parametri
child:DisplayObject — Reference to child whose index to get.
|
int — Number between 0 and (numChildren - 1).
|
getChildren | () | metodo |

The Container.layoutChrome() method is called regardless of the
value of the autoLayout property.
The Container.layoutChrome() method sets the
position and size of the Container container's border.
In every subclass of Container, the subclass's layoutChrome()
method should call the super.layoutChrome() method,
so that the border is positioned properly.
