Struct Slider 

pub struct Slider { /* private fields */ }

A draggable value between min and max. Arrow keys adjust it by step.

use ravenrs_reactive::State;
use ravenrs_widgets::{Slider, Ui};

let volume = State::new(40.0_f32);
let slider = Slider::new(volume.binding()).range(0.0, 100.0).step(5.0).width(240.0).show_value();
let mut ui = Ui::new(slider, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl Slider

pub fn new(value: Binding<f32>) -> Self

A slider over 0.0–1.0 bound to value, stepping by 0.01.

pub fn range(self, min: f32, max: f32) -> Self

The value range; also resets the step to 1/100 of the range.

pub fn step(self, step: f32) -> Self

The keyboard increment (call after Slider::range).

pub fn width(self, width: f32) -> Self

Fixed width in logical pixels; by default the slider stretches.

pub fn label(self, label: impl Into<String>) -> Self

The name screen readers announce, such as “Volume”.

pub fn marks(self, marks: impl IntoIterator<Item = f32>) -> Self

Notches on the track at these values, such as where chapters begin.

pub fn track_colors(self, colors: impl IntoIterator<Item = Color>) -> Self

Paints the track with these colors, evenly spaced from one end to the other, when the colors are what the value means, as from cold to warm. There is then no fill. The colors are data, so they come from whoever knows what they mean.

pub fn neutral(self, neutral: f32) -> Self

The value at rest, such as zero in the middle of the range. The fill starts there instead of at the minimum, and a double click, Backspace or Delete return to it.

pub fn show_value(self) -> Self

Shows the value at the right of the track, with as many decimals as the step has.

pub fn value_format(self, format: impl Fn(f32) -> String + 'static) -> Self

Shows the value at the right of the track as this function writes it, which screen readers read too.

Trait Implementations

impl Debug for Slider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl View for Slider

fn build(&self, cx: &mut BuildCx<'_>) -> NodeId

Creates this view’s node for the current build.

fn type_name(&self) -> &'static str

The name the diagnostics panel shows this view’s cost under.
