Struct Stepper 

pub struct Stepper { /* private fields */ }

A numeric stepper: decrement button, current value, increment button.

Implementations

impl Stepper

pub fn new(value: i64) -> Self

A stepper showing value (unbounded range, step 1 by default).

pub fn min(self, v: i64) -> Self

Lower bound (inclusive). The − button dims and stops firing there.

pub fn max(self, v: i64) -> Self

Upper bound (inclusive). The + button dims and stops firing there.

pub fn step(self, s: i64) -> Self

Increment per press (default 1; clamped to at least 1).

pub fn height(self, h: f32) -> Self

Control height in logical px (default 32.0).

pub fn font_size(self, s: f32) -> Self

Value/glyph text size (default: theme typography.body_medium).

pub fn radius(self, r: f32) -> Self

Corner radius of the track (default 6.0).

pub fn background(self, c: Color) -> Self

Track fill — defaults to the theme’s surface_variant.

pub fn color(self, c: Color) -> Self

Text/glyph tint — defaults to the theme’s on_surface.

pub fn border(self, c: Color, w: f32) -> Self

Outline stroke around the track (color, width).

pub fn on_change(self, f: impl Fn(i64) + Send + Sync + 'static) -> Self

Called with the new (already clamped) value on every effective press.

fn paint(&self, ctx: &mut PaintCtx<'_>)

Record draw commands for ctx.rect.

fn children(&self) -> Children<'_>

Declare this widget’s children. Drives every default below.

fn flex_factor(&self) -> f32

fn into_element(self) -> Element

where Self: Sized + 'static,

Wrap this widget in an Element so it can be returned from Component::build().
