InheritanceSimpleScrollBar Inheritance FeathersControl Inheritance starling.display.Sprite
Implements IDirectionalScrollBar

Product Version : Feathers 1.0.0

Select a value between a minimum and a maximum by dragging a thumb over a physical range. This type of scroll bar does not have a visible track, and it does not have increment and decrement buttons. It is ideal for mobile applications where the scroll bar is often simply a visual element to indicate the scroll position. For a more feature-rich scroll bar, see the ScrollBar component.

The following example updates a list to use simple scroll bars:

list.horizontalScrollBarFactory = function():IScrollBar
{
    return new SimpleScrollBar();
};
list.verticalScrollBarFactory = function():IScrollBar
{
    return new SimpleScrollBar();
};

Property Detail
clampToRangeproperty
public var clampToRange:Boolean = false

Determines if the value should be clamped to the range between the minimum and maximum. If false and the value is outside of the range, the thumb will shrink as if the range were increasing.

In the following example, the clamping behavior is updated:

scrollBar.clampToRange = true;

The default value is false.

globalStyleProviderproperty 
public static var globalStyleProvider:IStyleProvider

The default IStyleProvider for all SimpleScrollBar components.

The default value is null.

See also

thumbproperty 
protected var thumb:DisplayObject

The thumb sub-component.

For internal use in subclasses.

See also

thumbFactoryproperty 
thumbFactory:Function

A function used to generate the scroll bar's thumb sub-component. The thumb must be an instance of BasicButton. This factory can be used to change properties on the thumb when it is first created. For instance, if you are skinning Feathers components without a theme, you might use this factory to set skins and other styles on the thumb.

The function should have the following signature:

function():BasicButton

In the following example, a custom thumb factory is passed to the scroll bar:

scrollBar.thumbFactory = function():BasicButton
{
    var thumb:BasicButton = new BasicButton();
    var skin:ImageSkin = new ImageSkin( upTexture );
    skin.setTextureForState( ButtonState.DOWN, downTexture );
    thumb.defaultSkin = skin;
    return thumb;
};

The default value is null.


Implementation
    public function get thumbFactory():Function
    public function set thumbFactory(value:Function):void

See also

thumbPropertiesproperty 
thumbProperties:Object

An object that stores properties for the scroll bar's thumb, and the properties will be passed down to the thumb when the scroll bar validates. For a list of available properties, refer to feathers.controls.BasicButton.

If the subcomponent has its own subcomponents, their properties can be set too, using attribute @ notation. For example, to set the skin on the thumb which is in a SimpleScrollBar, which is in a List, you can use the following syntax:

list.verticalScrollBarProperties.@thumbProperties.defaultSkin = new Image(texture);

Setting properties in a thumbFactory function instead of using thumbProperties will result in better performance.

In the following example, the scroll bar's thumb properties are updated:

scrollBar.thumbProperties.defaultSkin = new Image( upTexture );
scrollBar.thumbProperties.downSkin = new Image( downTexture );

The default value is null.


Implementation
    public function get thumbProperties():Object
    public function set thumbProperties(value:Object):void

See also

thumbStyleNameproperty 
protected var thumbStyleName:String = "feathers-simple-scroll-bar-thumb"

The value added to the styleNameList of the thumb. This variable is protected so that sub-classes can customize the thumb style name in their constructors instead of using the default style name defined by DEFAULT_CHILD_STYLE_NAME_THUMB.

To customize the thumb style name without subclassing, see customThumbStyleName.

See also

valueproperty 
value:Number

The current numeric value.

In the following example, the value is changed to 12:

component.minimum = 0;
component.maximum = 100;
component.step = 1;
component.page = 10
component.value = 12;

The default value is 0.

Constructor Detail
SimpleScrollBar()Constructor
public function SimpleScrollBar()

Constructor.

Method Detail
autoSizeIfNeeded()method
protected function autoSizeIfNeeded():Boolean

If the component's dimensions have not been set explicitly, it will measure its content and determine an ideal size for itself. If the explicitWidth or explicitHeight member variables are set, those value will be used without additional measurement. If one is set, but not the other, the dimension with the explicit value will not be measured, but the other non-explicit dimension will still need measurement.

Calls saveMeasurements() to set up the actualWidth and actualHeight member variables used for layout.

Meant for internal use, and subclasses may override this function with a custom implementation.

Returns
Boolean
createThumb()method 
protected function createThumb():void

Creates and adds the thumb sub-component and removes the old instance, if one exists.

Meant for internal use, and subclasses may override this function with a custom implementation.

Event Detail
beginInteraction Event
Event Object Type: starling.events.Event
Event.type property = feathers.events.FeathersEventType.BEGIN_INTERACTION

Dispatched when the user starts dragging the scroll bar's thumb.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
currentTargetThe 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.
datanull
targetThe 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.

The FeathersEventType.BEGIN_INTERACTION event type is used by many UI controls where a drag or other interaction happens over time. An example is a Slider control where the user touches the thumb to begin dragging.
change Event  
Event Object Type: starling.events.Event
Event.type property = starling.events.Event.CHANGE

Dispatched when the scroll bar's value changes.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
currentTargetThe 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.
datanull
targetThe 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.

See also

endInteraction Event  
Event Object Type: starling.events.Event
Event.type property = feathers.events.FeathersEventType.END_INTERACTION

Dispatched when the user stops dragging the scroll bar's thumb.

The properties of the event object have the following values:

PropertyValue
bubblesfalse
currentTargetThe 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.
datanull
targetThe 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.

The FeathersEventType.END_INTERACTION event type is used by many UI controls where a drag or other interaction happens over time. An example is a Slider control where the user stops touching the thumb after dragging.

Depending on the control, the result of the interaction may continue after the interaction ends. For instance, a Scroller may be "thrown", and the scrolling will continue animating after the user has finished interacting with it.

Style Detail
paddingLeftstyle
paddingLeft:Number

The minimum space, in pixels, to the left of the thumb.

In the following example, the left padding is changed to 20 pixels:

scrollBar.paddingLeft = 20;

The default value is 0.

See also

paddingBottomstyle 
paddingBottom:Number

The minimum space, in pixels, below the thumb.

In the following example, the bottom padding is changed to 20 pixels:

The minimum space, in pixels, above the thumb.

In the following example, the top padding is changed to 20 pixels:

scrollBar.paddingTop = 20;

The default value is 0.

See also

paddingstyle 
padding:Number

Quickly sets all padding properties to the same value. The padding getter always returns the value of paddingTop, but the other padding values may be different.

In the following example, the padding is changed to 20 pixels:

scrollBar.padding = 20;

The default value is 0.

See also

directionstyle 
direction:String

Determines if the scroll bar's thumb can be dragged horizontally or vertically. When this value changes, the scroll bar's width and height values do not change automatically.

Note: When using a SimpleScrollBar with a scrolling container, the container will automatically set the correct direction value. Generally, you should not need to set this style manually.

In the following example, the direction is changed to vertical:

scrollBar.direction = Direction.VERTICAL;

Note: The Direction.NONE constant is not supported.

The default value is feathers.layout.Direction.HORIZONTAL.

See also

customThumbStyleNamestyle 
customThumbStyleName:String

A style name to add to the scroll bar's thumb sub-component. Typically used by a theme to provide different styles to different scroll bars.

In the following example, a custom thumb style name is passed to the scroll bar:

scrollBar.customThumbStyleName = "my-custom-thumb";

In your theme, you can target this sub-component style name to provide different styles than the default:

getStyleProviderForClass( Button ).setFunctionForStyleName( "my-custom-thumb", setCustomThumbStyles );

The default value is null.
