Struct Protractor 

pub struct Protractor { /* private fields */ }

A band of ticks along an arc that sets an angle, by a drag from anywhere on it. A double click goes back to zero. The arrows change it by a step (with Shift, ten), Home and End go to the ends, and Delete goes back to zero.

use ravenrs_reactive::State;
use ravenrs_widgets::Protractor;

let angle = State::new(0.0_f32);
let straighten = Protractor::new(angle.binding()).range(-45.0, 45.0).label("Straighten");

Implementations

impl Protractor

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

A band bound to value, in degrees, from -45 to 45 in steps of 0.1.

pub fn range(self, least: f32, most: f32) -> Self

The least and the most it reaches, in degrees.

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

The smallest change, in degrees (0.1 by default).

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

Its width in logical pixels (260 by default).

pub fn on_commit(self, handler: impl Fn(f32) + 'static) -> Self

Runs handler with the angle when a drag ends or a key or double click changes it: one step to undo.

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

Shows the angle without letting it change.

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

The name screen readers announce, instead of the one in Labels.
