ValueSlider

abstract class ValueSlider<T : Comparable<T>> : View(source)

Base class for controls that represent sliders. These controls have a single value that is bound between a range defined by model. ValueSliders can be conceptualized as mapping between two domains as follows:

Parameters

model

used to represent the slider's value and limits

interpolator

used in mapping between T and the slider's domain: 0-1

function

used to map between the slider's input and output.

Inheritors

Properties

var fraction: Float

Value of the slider as a fraction between 0-1.

var marker: Marker<T>?

Provides marks that should show up on the slider.

var model: ConfinedValueModel<T>

Model that represents the slider's value and range.

var range: ClosedRange<T>

Slider's current range: start - end.

protected val role: SliderRole

var snappingPolicy: SnappingPolicy<T>?

Determines how the slider snaps to marks.

var ~~snapToTicks~~: Boolean

Indicates whether the slider should only take on values at the specify tick interval.

var ~~ticks~~: Int

Number of ticks the slider should have.

var value: T

Slider's current value.

valueAccessibilityLabeler

var valueAccessibilityLabeler: (T) -> String?

Human-understandable text to represent the current value if the number is insufficient.
