If true, measurement and layout are done
when the position or size of a child is changed.
If false, measurement and layout are done only once,
when children are added to or removed from the container.
When using the Move effect, the layout around the component that
is moving does not readjust to fit that the Move effect animates.
Setting a container's autoLayout property to
true has no effect on this behavior.
The Zoom effect does not work when the autoLayout
property is false.
The autoLayout property does not apply to
Accordion or ViewStack containers.

creationPolicy:String| Language Version: | ActionScript 3.0 |

| Runtime Versions: | Flash Player 9, AIR 1.1 |
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.
The default value is ContainerCreationPolicy.AUTO.

direction | property |
direction:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Determines how children are placed in the container.
Possible MXML values are "horizontal" and
"vertical".
In ActionScript, you can set the direction using the values
TileDirection.HORIZONTAL or TileDirection.VERTICAL.
The default value is "horizontal".
(If the container is a Legend container, which is a subclass of Tile,
the default value is "vertical".)
The first child is always placed at the upper-left of the
Tile container.
If the direction is "horizontal",
the children are placed left-to-right in the topmost row,
and then left-to-right in the second row, and so on.
If the value is "vertical", the children are placed
top-to-bottom in the leftmost column, and then top-to-bottom
in the second column, and so on.
The default value is "horizontal".
This property can be used as the source for data binding. When this property is modified, it dispatches the directionChanged event.

Number of child components in this container.
The number of children is initially equal

rawChildren:IChildList [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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.

public function get rawChildren():IChildListverticalScrollPosition | property |
verticalScrollPosition:Number| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |

The current position of the vertical scroll bar. This is equal to the distance in pixels between the top edge of the scrollable surface and the topmost piece of the surface that is currently visible.
The default value is 0.
This property can be used as the source for data binding. When this property is modified, it dispatches the viewChanged event.

viewMetrics:EdgeMetrics [read-only] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Returns an object that has four properties: left,
top, right, and bottom.
The value of each property equals the thickness of the chrome
(visual elements) around the edge of the container.
The chrome includes the border thickness.
If the horizontalScrollPolicy or verticalScrollPolicy
property value is ScrollPolicy.ON, the
chrome also includes the thickness of the corresponding
scroll bar. If a scroll policy is ScrollPolicy.AUTO,
the chrome measurement does not include the scroll bar thickness,
even if a scroll bar is displayed.
Subclasses of Container should override this method, so that
they include other chrome to be taken into account when positioning
the Container's children.
For example, the viewMetrics property for the
Panel class should return an object whose top property
includes the thickness of the Panel container's title bar.

Returns an object that has four properties: left,
top, right, and bottom.
The value of each property is equal to the thickness of the chrome

around the edge of the container plus the thickness of the object's margins.
The chrome includes the border thickness.
If the horizontalScrollPolicy or verticalScrollPolicy
property value is ScrollPolicy.ON, the
chrome also includes the thickness of the corresponding

addChild | () | method |
override public function addChild(child:DisplayObject):DisplayObject| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Adds a child DisplayObject to this Container. The child is added after other existing children, so that the first child added has index 0, the next has index 1, an so on.
Note: While the child argument to the method
is specified as of type DisplayObject, the argument must implement
the IUIComponent interface to be added as a child of a container.
All Flex components implement this interface.
Children are layered from back to front.
In other words, if children overlap, the one with index 0
is farthest to the back, and the one with index
numChildren - 1 is frontmost.
This means the newly added children are layered
in front of existing children.
Parameters
child:DisplayObject — The DisplayObject to add as a child of this Container.
It must implement the IUIComponent interface.
|
DisplayObject — The added child as an object of type DisplayObject.
You typically cast the return value to UIComponent,
or to the type of the added component.

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Adds a child DisplayObject to this Container. The child is added at the index specified.
Note: While the child argument to the method
is specified as of type DisplayObject, the argument must implement
the IUIComponent interface to be added as a child of a container.
All Flex components implement this interface.
Children are layered from back to front.
In other words, if children overlap, the one with index 0
is farthest to the back, and the one with index
numChildren - 1 is frontmost.
This means the newly added children are layered
in front of existing children.
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). If you want to replace an old child, you must first remove it before adding the new one.
Parameters
child:DisplayObject — The DisplayObject to add as a child of this Container.
It must implement the IUIComponent interface.
| |
index:int — The index to add the child at.
|
DisplayObject — The added child as an object of type DisplayObject.
You typically cast the return value to UIComponent,

| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Converts a Point object from content coordinates to global coordinates.
Content coordinates specify a pixel position relative to the upper left corner
of the component's content, and include all of the component's content area,
including any regions that are currently clipped and must be
accessed by scrolling the component.
You use the content coordinate system to set and get the positions of children
of a container that uses absolute positioning.
Global coordinates specify a pixel position relative to the upper-left corner
of the stage, that is, the outermost edge of the application.
Parameters
point:Point — A Point object that
specifies the x and y coordinates in the content coordinate system
as properties.
|
Point — A Point object with coordinates relative to the Stage.

createComponentFromDescriptor | () | method |
public function createComponentFromDescriptor(descriptor:ComponentDescriptor, recurse:Boolean):IFlexDisplayObject| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Given a single UIComponentDescriptor, create the corresponding component and add the component as a child of this container.
This method instantiates the new object but does not add it to the display list, so the object does not
appear on the screen by default. To add the new object to the display list, call the validateNow()
method on the container after calling the createComponentFromDescriptor() method,
as the following example shows:
myVBox.createComponentFromDescriptor(myVBox.childDescriptors[0],false);
myVBox.validateNow();
Alternatively, you can call the createComponentsFromDescriptors() method on the
container to create all components at one time. You are not required to call the validateNow()
method after calling the createComponentsFromDescriptors() method.
Parameters
descriptor:ComponentDescriptor — The UIComponentDescriptor for the
component to be created. This argument is either a
UIComponentDescriptor object or the index of one of the container's
children (an integer between 0 and n-1, where n is the total
number of children of this container).
| |
recurse:Boolean — If false, create this component
but none of its children.
If true, after creating the component, Flex calls
the createComponentsFromDescriptors() method to create all or some
of its children, based on the value of the component's creationPolicy property.
|
IFlexDisplayObject — The component that is created.

Iterate through the Array of childDescriptors,
and call the createComponentFromDescriptor() method for each one.
If the value of the container's creationPolicy property is
ContainerCreationPolicy.ALL, then this method is called
automatically during the initialization sequence.
If the value of the container's creationPolicy is
ContainerCreationPolicy.AUTO,
then this method is called automatically when the
container's children are about to become visible.
If the value of the container's creationPolicy property is
ContainerCreationPolicy.NONE,
then you should call this function
when you want to create this container's children.

executeBindings | () | method |
override public function executeBindings(recurse:Boolean = false):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Executes all the data bindings on this Container. Flex calls this method automatically once a Container has been created to cause any data bindings that have destinations inside of it to execute. 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.
Parameters
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.
|
executeChildBindings | () | method |
public function executeChildBindings(recurse:Boolean):void| Language Version: | ActionScript 3.0 |

| Runtime Versions: | Flash Player 9, AIR 1.1 |
Executes the bindings into this Container's child UIComponent objects. Flex calls this method automatically once a Container has been created.
Parameters
recurse:Boolean — If false, then only execute the bindings
on the immediate children of this Container.
If true, then also execute the bindings on this
container's grandchildren,
great-grandchildren, and so on.

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.
Parameters
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 | () | method |
override public function getChildByName(name:String):DisplayObject| Language Version: | ActionScript 3.0 |

Returns the child whose name property is the specified String.
Parameters
name:String — The identifier of the child.
|
DisplayObject — The DisplayObject representing 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.
Throws a run-time error if the child of the specified name does not exist.
|
getChildIndex | () | method |
override public function getChildIndex(child:DisplayObject):int| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | 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.
Parameters
child:DisplayObject — Reference to child whose index to get.
|
int — Number between 0 and (numChildren - 1).
|
getChildren | () | method |

protected function layoutChrome(unscaledWidth:Number, unscaledHeight:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Respond to size changes by setting the positions and sizes of this container's borders. This is an advanced method that you might override when creating a subclass of Container.
Flex calls the layoutChrome() method when the
container is added to a parent container using the addChild() method,
and when the container's invalidateDisplayList() method is called.
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.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.

See the getChildIndex() method for a
description of the child's index.
Parameters
child:DisplayObject — Reference to child whose index to set.
| |
newIndex:int — Number that indicates the new index.
Must be an integer between 0 and (numChildren - 1).

setElementIndex | () | method |
public function setElementIndex(element:IVisualElement, index:int):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | 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.
Parameters
element:IVisualElement — The element for which you want to change the index number.
| |
index:int — The resulting index number for the element.
|
swapElements | () | method |
public function swapElements(element1:IVisualElement, element2:IVisualElement):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Swaps the index of the two specified visual elements. All other elements remain in the same index position.
Parameters
element1:IVisualElement — The first visual element.
| |
element2:IVisualElement — The second visual element.
|
swapElementsAt | () | method |
public function swapElementsAt(index1:int, index2:int):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 4 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Swaps the visual elements at the two specified index positions in the container. All other visual elements remain in the same index position.
Parameters
index1:int — The index of the first element.
| |
index2:int — The index of the second element.
|
updateDisplayList | () | method |
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Respond to size changes by setting the positions and sizes of this container's children.
See the UIComponent.updateDisplayList() method for more information
about the updateDisplayList() method.
The Container.updateDisplayList() method sets the position
and size of the Container container's border.
In every subclass of Container, the subclass's updateDisplayList()
method should call the super.updateDisplayList() method,
so that the border is positioned properly.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
| |
unscaledHeight:Number — Specifies the height of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleY property of the component.

childAdd | Event |
mx.events.ChildExistenceChangedEventproperty ChildExistenceChangedEvent.type =
mx.events.ChildExistenceChangedEvent.CHILD_ADD| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched after a child has been added to a legend.
The childAdd event is dispatched when the addChild()
or addChildAt() method is called.
When a container is first created, the addChild()
method is automatically called for each child component declared
in the MXML file.
The addChildAt() method is automatically called
whenever a Repeater object adds or removes child objects.
The application developer may also manually call these
methods to add new children.
At the time when this event is sent, the child object has been
initialized, but its width and height have not yet been calculated,
and the child has not been drawn on the screen.
If you want to be notified when the child has been fully initialized
and rendered, then register as a listener for the child's
creationComplete event.
ChildExistenceChangedEvent.CHILD_ADD constant
defines the value of the type property of the event
object for a childAdd event.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
relatedObject | Contains a reference to the child object that was created. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |

Dispatched after the index (among the legend children)
of a legend child changes.
This event is only dispatched for the child specified as the argument to
the setChildIndex() method; it is not dispatched
for any other child whose index changes as a side effect of the call
to the setChildIndex() method.
The child's index is changed when the
setChildIndex() method is called.
type property of the event object for a childIndexChange event,
which indicates that a component's index among a container's children
has changed.
The properties of the event object have the following values:
| Property | Value |

myButton is the value of the currentTarget. |
inputType | Indicates whether this event was caused by a mouse or keyboard interaction. |
newIndex | The zero-based index of the child after the change. |
oldIndex | The zero-based index of the child before the change. |
relatedObject | Contains a reference to the child object whose index changed. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
