page | property |
page:Number
The amount the scroll bar value must change to get from one "page" to the next.
If this value is 0
, the step
value
will be used instead. If the step
value is
0
, paging is not possible.
In the following example, the page is changed to 10:
scrollBar.minimum = 0; scrollBar.maximum = 100; scrollBar.step = 1; scrollBar.page = 10 scrollBar.value = 12;
The default value is 0
.

repeatDelay | property |
repeatDelay:Number
The time, in seconds, before actions are repeated. The first repeat happens after a delay that is five times longer than the following repeats.
In the following example, the repeat delay is changed to 500 milliseconds:
scrollBar.repeatDelay = 0.5;
The default value is 0.05
.
public function get repeatDelay():Number
public function set repeatDelay(value:Number):void
step | property |
step:Number
The amount the value must change to increment or decrement.
In the following example, the step is changed to 1:
component.minimum = 0; component.maximum = 100; component.step = 1; component.page = 10 component.value = 12;
The default value is 0
.

thumb | property |
thumbFactory | property |
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
.
public function get thumbFactory():Function
public function set thumbFactory(value:Function):void
See also
thumbProperties | property |
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
.
public function get thumbProperties():Object
public function set thumbProperties(value:Object):void

thumbStyleName | property |
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
.

value | property |
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.
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.
ReturnsBoolean |
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.

beginInteraction | Event |
starling.events.Event
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:
Property | Value |
---|---|
bubbles | 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 . |
data | null |
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. |
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 |
starling.events.Event
starling.events.Event.CHANGE
Dispatched when the scroll bar's value changes.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | 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 . |
data | null |
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 when the user stops dragging the scroll bar's thumb.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | 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 . |
data | null |
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. |
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.
DEFAULT_CHILD_STYLE_NAME_THUMB | Constant |
public static const DEFAULT_CHILD_STYLE_NAME_THUMB:String = feathers-simple-scroll-bar-thumb
The default value added to the styleNameList
of the thumb.
