Product Version : Feathers 1.0.0

A generic container that supports layout, scrolling, and a background skin. For a lighter container, see LayoutGroup, which focuses specifically on layout without scrolling.

The following example creates a scroll container with a horizontal layout and adds two buttons to it:

var container:ScrollContainer = new ScrollContainer();
var layout:HorizontalLayout = new HorizontalLayout();
layout.gap = 20;
layout.padding = 20;
container.layout = layout;
this.addChild( container );

var yesButton:Button = new Button();
yesButton.label = "Yes";
container.addChild( yesButton );

var noButton:Button = new Button();
noButton.label = "No";
container.addChild( noButton );

Property Detail
autoSizeModeproperty
autoSizeMode:String

Determines how the container will set its own size when its dimensions (width and height) aren't set explicitly.

In the following example, the container will be sized to match the stage:

container.autoSizeMode = AutoSizeMode.STAGE;

Usually defaults to AutoSizeMode.CONTENT. However, if this component is the root of the Starling display list, defaults to AutoSizeMode.STAGE instead.


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

See also

displayListBypassEnabledproperty 
protected var displayListBypassEnabled:Boolean = true

A flag that indicates if the display list functions like addChild() and removeChild() will be passed to the internal view port.

globalStyleProviderproperty 
public static var globalStyleProvider:IStyleProvider

The default IStyleProvider for all ScrollContainer components.

The default value is null.

See also

isChildFocusEnabledproperty 
isChildFocusEnabled:Boolean

Determines if this component's children can receive focus. This property is completely independent from the isFocusEnabled property. In other words, it's possible to disable focus on this component while still allowing focus on its children (or the other way around).

In the following example, the focus is disabled:

object.isFocusEnabled = false;

The default value is true.


Implementation
    public function get isChildFocusEnabled():Boolean
    public function set isChildFocusEnabled(value:Boolean):void

Style Detail
layoutstyle
layout:ILayout

Controls the way that the container's children are positioned and sized.

The following example tells the container to use a horizontal layout:

var layout:HorizontalLayout = new HorizontalLayout();
layout.gap = 20;
layout.padding = 20;
container.layout = layout;

The default value is null.

Constant Detail
ALTERNATE_STYLE_NAME_TOOLBARConstant
public static const ALTERNATE_STYLE_NAME_TOOLBAR:String = "feathers-toolbar-scroll-container"

An alternate style name to use with ScrollContainer to allow a theme to give it a toolbar style. If a theme does not provide a style for the toolbar container, the theme will automatically fall back to using the default scroll container skin.

An alternate style name should always be added to a component's styleNameList before the component is initialized. If the style name is added later, it will be ignored.

In the following example, the toolbar style is applied to a scroll container:

var container:ScrollContainer = new ScrollContainer();
container.styleNameList.add( ScrollContainer.ALTERNATE_STYLE_NAME_TOOLBAR );
this.addChild( container );
