Style | Description | Defined By | ||
---|---|---|---|---|
accentColor | Type: uint Format: Color CSS Inheritance: yes Theme: spark Accent color used by component skins. The default button skin uses this color to tint the background. Slider track highlighting uses this color. The default value is #0099FF . | Container | ||
backgroundAlpha | Type: Number CSS Inheritance: no Theme: halo, spark Alpha level of the color defined by the backgroundColor
property, of the image or SWF file defined by the backgroundImage
style.
Valid values range from 0.0 to 1.0. For most controls, the default value is 1.0,
but for ToolTip controls, the default value is 0.95 and for Alert controls, the default value is 0.9.
The default value is 1.0 . | Container | ||
backgroundAttachment | Type: String CSS Inheritance: no If a background image is specified, this style specifies whether it is fixed with regard to the viewport ( "fixed" )
or scrolls along with the content ("scroll" ).
The default value is "scroll" . | Container | ||
backgroundColor | Type: uint Format: Color CSS Inheritance: no Theme: halo, spark Background color of a component. You can have both a backgroundColor and a
backgroundImage set.
Some components do not have a background.
The DataGrid control ignores this style.
The default value is undefined , which means it is not set.
If both this style and the backgroundImage style
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
alpha values of the control's <mx:Container backgroundColor="0x66CC66"/> <mx:ControlName ... fillAlphas="[1,1]"/> </mx:Container> | Container | ||
backgroundDisabledColor | Type: uint Format: Color CSS Inheritance: yes Theme: halo Background color of the component when it is disabled. The global default value is undefined .

backgroundImage . The background image is displayed
on top of the background color.
The default value is undefined , meaning "not set".
If this style and the backgroundColor style are undefined,
the component has a transparent background.
The default skins of most Flex controls are partially transparent. As a result, the background image of
a container partially "bleeds through" to controls that are in that container. You can avoid this by setting the
alpha values of the control's <mx:Container backgroundColor="0x66CC66"/> <mx:ControlName ... fillAlphas="[1,1]"/> </mx:Container> | Container | ||
backgroundSize | Type: String CSS Inheritance: no Theme: halo Scales the image specified by backgroundImage
to different percentage sizes.
A value of "100%" stretches the image
to fit the entire component.

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

creationPolicy | property |
creationPolicy:String
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
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
.

rawChildren | property |
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.

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.

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.

override public function addChildAt(child:DisplayObject, index:int):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 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,
or to the type of the added component.

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.

createComponentsFromDescriptors | () | method |
public function createComponentsFromDescriptors(recurse:Boolean = true):void
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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.
Parameters
recurse:Boolean (default = true ) — If true , recursively
create components.
|
createDeferredContent | () | method |
public function createDeferredContent():void
Language Version : | ActionScript 3.0 |
Product Version : | Flex 4 |
Runtime Versions : | Flash Player 10, AIR 1.5 |
Performs the equivalent action of calling
the createComponentsFromDescriptors(true)
method for containers
that implement the IDeferredContentOwner interface to support deferred instantiation.

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 ) — If 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 |
Product Version : | Flex 3 |
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.

getChildAt | () | method |
override public function getChildAt(index:int):DisplayObject
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | 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.
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 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
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 |
public function getChildren():Array
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |

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.
| |
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.

Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Converts a Point
object from local to content coordinates.
Local coordinates specify a pixel position relative to the
upper left corner of the component.
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.
Parameters

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.
