The SkinnableContainer class is the base class for skinnable containers that have visual content. The SkinnableContainer container takes as children any components that implement the IVisualElement interface. All Spark and Halo components implement the IVisualElement interface, as does the GraphicElement class. That means the container can use the graphics classes, such as Rect and Ellipse, as children.

To improve performance and minimize application size, you can use the Group container. The Group container cannot be skinned.

The SkinnableContainer container has the following default characteristics:

CharacteristicDescription
Default sizeLarge enough to display its children
Minimum size0 pixels
Maximum size10000 pixels wide and 10000 pixels high

Common Styles
 Style Description Defined By
  
alignmentBaseline
Type: String CSS Inheritance: yes
Specifies the baseline to which the dominant baseline aligns. For example, if you set dominantBaseline to ASCENT, setting alignmentBaseline to DESCENT aligns the top of the text with the DESCENT baseline, or below the line. The largest element in the line generally determines the baselines.

baselines

Legal values are flash.text.engine.TextBaseline.ROMAN, flash.text.engine.TextBaseline.ASCENT, flash.text.engine.TextBaseline.DESCENT, flash.text.engine.TextBaseline.IDEOGRAPHIC_TOP, flash.text.engine.TextBaseline.IDEOGRAPHIC_CENTER, flash.text.engine.TextBaseline.IDEOGRAPHIC_BOTTOM, flash.text.engine.TextBaseline.USE_DOMINANT_BASELINE, flashx.textLayout.formats.FormatValue.INHERIT.

For all languages except Japanese and Chinese, FormatValue.AUTO becomes JustificationRule.SPACE, which adds extra space to the space characters. For Japanese and Chinese, FormatValue.AUTO becomes JustficationRule.EAST_ASIAN. In part, justification changes the spacing of punctuation. In Roman text the comma and Japanese periods take a full character's width but in East Asian text only half of a character's width. Also, in the East Asian text the spacing between sequential punctuation marks becomes tighter, obeying traditional East Asian typographic conventions. Note, too, in the example below the leading that is applied to the second line of the paragraphs. In the East Asian version, the last two lines push left. In the Roman version, the second and following lines push left.

justificationRule

Legal values are flashx.textLayout.formats.JustificationRule.EAST_ASIAN, flashx.textLayout.formats.JustificationRule.SPACE, flashx.textLayout.formats.FormatValue.AUTO, flashx.textLayout.formats.FormatValue.INHERIT.

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Content creation policy for this component.

Possible values are:

  • auto - Automatically create the content immediately before it is needed.
  • all - Create the content as soon as the parent component is created. This option should only be used as a last resort because it increases startup time and memory usage.
  • none - Content must be created manually by calling the createDeferredContent() method.

If no creationPolicy is specified for a container, that container inherits the value of its parent's creationPolicy property.

The default value is auto.



Implementation
    public function get creationPolicy():String
    public function set creationPolicy(value:String):void

deferredContentCreated

property 
deferredContentCreated:Boolean  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Contains true if deferred content has been created.



Implementation
    public function get deferredContentCreated():Boolean

layout

property 
layout:LayoutBase

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The layout object for this container. This object is responsible for the measurement and layout of the visual elements in the container.

The default value is BasicLayout.



Implementation
    public function get layout():LayoutBase
    public function set layout(value:LayoutBase):void

mxmlContent

property 
mxmlContent:Array  [write-only]

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The visual content children for this Group. This method is used internally by Flex and is not intended for direct use by developers.

The content items should only be IVisualElement objects. An mxmlContent Array should not be shared between multiple Group containers because visual elements can only live in one container at a time.

If the content is an Array, do not modify the Array directly. Use the methods defined by the Group class instead.



Implementation
    public function set mxmlContent(value:Array):void

mxmlContentFactory

property 
mxmlContentFactory:IDeferredInstance  [write-only]

Language Version: ActionScript 3.0
Product Version: Flex 4

A factory object that creates the initial value for the content property.



Implementation
    public function set mxmlContentFactory(value:IDeferredInstance):void

numElements

property 
numElements:int  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: 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.

Parameters

element:IVisualElement — The visual element to add as a child of this container.

Returns
IVisualElement — The element that was added.

addElementAt

()method 
public function addElementAt(element:IVisualElement, index:int):IVisualElement

Language Version: ActionScript 3.0

partAdded

()method 
override protected function partAdded(partName:String, instance:Object):void

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Called when a skin part is added. You do not call this method directly. For static parts, Flex calls it automatically when it calls the attachSkin() method. For dynamic parts, Flex calls it automatically when it calls the createDynamicPartInstance() method.

Override this function to attach behavior to the part. If you want to override behavior on a skin part that is inherited from a base class, do not call the super.partAdded() method. Otherwise, you should always call the super.partAdded() method.

Parameters

partName:String — The name of the part.
 
instance:Object — The instance of the part.

partRemoved

()method 
override protected function partRemoved(partName:String, instance:Object):void
