SliderState

class SliderState(initialValue: Double, val range: ClosedFloatingPointRange<Double> = 0.0..1.0, val steps: Int = 0)(source)

Caller-owned owner-thread numeric state for one Slider.

Values are finite, clamped to SliderState.range, and quantized to SliderState.steps evenly spaced interior stops when steps are requested. Distinct normalized writes synchronously invalidate attached retained observers.

Parameters

initialValue

initial value normalized into SliderState.range.

Constructors

SliderState

constructor(initialValue: Double, range: ClosedFloatingPointRange<Double> = 0.0..1.0, steps: Int = 0)

Properties

fraction

val fraction: Double

Current zero-to-one fraction within SliderState.range.

range

val range: ClosedFloatingPointRange<Double>

finite increasing inclusive range.

steps

val steps: Int

number of evenly spaced selectable values excluding both endpoints.

value

var value: Double

Current normalized value.

Functions

observe

fun observe(callback: (Double) -> Unit): ComponentStateSubscription

Installs one privileged retained observer.
