liveDragging | property |
public var liveDragging:Boolean = true
Determines if the slider dispatches the Event.CHANGE
event every time the thumb moves, or only once it stops moving.
In the following example, live dragging is disabled:
slider.liveDragging = false;
The default value is true
.
maximum | property |
maximum:Number
The slider's value will not go higher than the maximum. The maximum
is zero (0
), by default, and it should almost always be
changed to something more appropriate.
In the following example, the maximum is set to 100:
slider.minimum = 0; slider.maximum = 100; slider.step = 1; slider.page = 10 slider.value = 12;
The default value is 0
.
public function get maximum():Number
public function set maximum(value:Number):void

maximumTrack | property |
protected var maximumTrack:DisplayObject
The maximum track sub-component.
For internal use in subclasses.
See also
maximumTrackFactory | property |
maximumTrackFactory:Function
A function used to generate the slider's maximum track sub-component.
The maximum track must be an instance of BasicButton
(or
a subclass). This factory can be used to change properties on the
maximum track 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 maximum track.
The function should have the following signature:
function():BasicButton
In the following example, a custom maximum track factory is passed to the slider:
slider.maximumTrackFactory = function():BasicButton { var track:BasicButton = new BasicButton(); var skin:ImageSkin = new ImageSkin( upTexture ); skin.setTextureForState( ButtonState.DOWN, downTexture ); track.defaultSkin = skin; return track; };
The default value is null
.
public function get maximumTrackFactory():Function
public function set maximumTrackFactory(value:Function):void
See also
maximumTrackProperties | property |
maximumTrackProperties:Object
An object that stores properties for the slider's "maximum" track,
and the properties will be passed down to the "maximum" track when
the slider 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 maximumTrackFactory
function
instead of using maximumTrackProperties
will result in
better performance.
In the following example, the slider's maximum track properties are updated:
slider.maximumTrackProperties.defaultSkin = new Image( upTexture ); slider.maximumTrackProperties.downSkin = new Image( downTexture );
The default value is null
.
public function get maximumTrackProperties():Object
public function set maximumTrackProperties(value:Object):void

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.

beginInteraction | Event |
starling.events.Event
feathers.events.FeathersEventType.BEGIN_INTERACTION
Dispatched when the user starts dragging the slider's thumb or track.
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 slider'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

Dispatched when the user stops dragging the slider's thumb or track.
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 . |

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.
trackScaleMode | style |
trackScaleMode:String
Determines how the minimum and maximum track skins are positioned and sized.
In the following example, the slider's track layout is customized:
slider.trackScaleMode = TrackScaleMode.EXACT_FIT;
The default value is feathers.controls.TrackScaleMode.DIRECTIONAL
.
See also
trackLayoutMode | style |
trackLayoutMode:String
Determines how the minimum and maximum track skins are positioned and sized.
In the following example, the slider is given two tracks:
slider.trackLayoutMode = TrackLayoutMode.SPLIT;
The default value is feathers.controls.TrackLayoutMode.SINGLE
.
See also
trackInteractionMode | style |
trackInteractionMode:String
Determines how the slider's value changes when the track is touched.
If showThumb
is set to false
, the slider
will always behave as if trackInteractionMode
has been
set to TrackInteractionMode.TO_VALUE
. In other
words, the value of trackInteractionMode
may be ignored
if the thumb is hidden.
In the following example, the slider's track interaction is changed:
slider.trackScaleMode = TrackInteractionMode.BY_PAGE;
The default value is TrackInteractionMode.TO_VALUE
.
See also
thumbOffset | style |
thumbOffset:Number
Offsets the position of the thumb by a certain number of pixels in a direction perpendicular to the track. This does not affect the measurement of the slider. The slider will measure itself as if the thumb were not offset from its original position.
In the following example, the thumb is offset by 20 pixels:
slider.thumbOffset = 20;
The default value is 0
.
showThumb | style |
showThumb:Boolean
Determines if the thumb should be displayed.
In the following example, the thumb is hidden:
slider.showThumb = false;
The default value is true
.
minimumPadding | style |
minimumPadding:Number
The space, in pixels, between the minimum position of the thumb and the minimum edge of the track. May be negative to extend the range of the thumb.
In the following example, minimum padding is set to 20 pixels:
slider.minimumPadding = 20;
The default value is 0
.
See also
maximumPadding | style |
maximumPadding:Number
The space, in pixels, between the maximum position of the thumb and the maximum edge of the track. May be negative to extend the range of the thumb.
In the following example, maximum padding is set to 20 pixels:
slider.maximumPadding = 20;
The default value is 0
.
See also
direction | style |
direction:String
Determines if the slider's thumb can be dragged horizontally or vertically. When this value changes, the slider's width and height values do not change automatically.
In the following example, the direction is changed to vertical:
slider.direction = Direction.VERTICAL;
Note: The Direction.NONE
constant is not supported.
The default value is feathers.layout.Direction.HORIZONTAL
.

customThumbStyleName | style |
customThumbStyleName:String
A style name to add to the slider's thumb sub-component. Typically used by a theme to provide different styles to different sliders.
In the following example, a custom thumb style name is passed to the slider:
slider.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
.
