Struct ValueSlider 

pub struct ValueSlider { /* private fields */ }

A value shown small, as “100% ▾”, that opens a Slider in a popover, for bars with no room for a slider of their own.

Enter or Space on the button opens it with the keyboard in the slider: the arrows, Home and End change the value, and Escape closes it and goes back to the button. With ValueSlider::field the number can also be typed.

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

let opacity = State::new(100.0_f32);
let control = ValueSlider::new(opacity.binding()).range(0.0, 100.0).step(1.0).unit("%").label("Opacity");
let mut ui = Ui::new(control, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl ValueSlider

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

A control 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 ValueSlider::range).

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

Text right after the number, such as % or px.

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

What the value is, such as “Opacity”, for screen readers. See Self::show_label.

pub fn show_label(self) -> Self

Also writes the label before the value.

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

Writes the value as this function does, instead of the number and the unit. Self::field goes on showing the number, since that is what can be typed.

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

The value at rest: see Slider::neutral.

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

The width of the slider in the popover, in logical pixels (200 by default).

pub fn field(self) -> Self

A number field with the unit and a small arrow that opens the slider, instead of a button. Enter or leaving the field takes what was typed, up to the limits; text that is not a number, or Escape, brings the value back. Up and Down take a step.

pub fn disabled(self, disabled: bool) -> Self

Turns it off: it fades, leaves the tab order and does not open.

Trait Implementations

impl Debug for ValueSlider

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

Formats the value using the given formatter.

impl View for ValueSlider

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.
