Struct ProgressBar 

pub struct ProgressBar<C: PixelColor, M: Clone> { /* private fields */ }

Passive progress bar reflecting a value within a range.

Implementations

impl<C: PixelColor, M: Clone> ProgressBar<C, M>

pub fn new(value: f32) -> Self

New progress bar showing value. Default range is 0.0..=1.0.

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

Inclusive value range mapped to the fill fraction.

pub fn color(self, color: C) -> Self

Explicit fill color (default: theme.accent.base).

pub fn width(self, width: impl Into<Length>) -> Self

Width sizing intent.

pub fn height(self, height: impl Into<Length>) -> Self

Height sizing intent.

Trait Implementations

impl<C: PixelColor, M: Clone> Widget<C, M> for ProgressBar<C, M>

fn measure(&mut self, constraints: Constraints) -> Size

Report the size this widget wants within constraints.

fn preferred_size(&self) -> (Length, Length)

Per-axis sizing intent set via .width(...) / .height(...). Containers consult this during layout to allocate fixed slots, query intrinsic sizes, and split residual space among Fill / FillPortion children. Default is Length::Fill on both axes.

fn arrange(&mut self, rect: Rectangle)

Commit the final rectangle, recursively arranging any children.

fn rect(&self) -> Rectangle

The current arranged rectangle.

fn handle_touch(&mut self, _point: Point, _phase: TouchPhase) -> Option<M>

Dispatch a touch event. Returns a message if consumed.

fn draw<'t>( &self, renderer: &mut dyn Renderer<C>, theme: &Theme<'t, C>, ) -> Result<(), RenderError>

Paint into renderer at rect.

fn mark_pressed(&mut self, point: Point)

Set this widget’s pressed flag if point hits. No message emit. Containers forward to children. Default no-op.

fn widget_id(&self) -> Option<WidgetId>

Stable id of this widget, if it participates in focus.

fn is_focusable(&self) -> bool

True if this widget should appear in focus traversal.

fn collect_focusable(&self, out: &mut Vec<WidgetId>)

Append focusable widget ids in traversal order.

fn sync_focus(&mut self, focused: Option<WidgetId>)

Synchronize focused state against the runtime’s currently-focused id.

fn handle_action(&mut self, action: UiAction) -> Option<M>

Handle a semantic action directed at this widget.

fn route_action(&mut self, target: WidgetId, action: UiAction) -> Option<M>

Route a semantic action to the widget with id target.

fn navigate_focus(&self, target: WidgetId, action: UiAction) -> Option<WidgetId>

Request a focus movement relative to target for directional actions.

fn focus_rect(&self, target: WidgetId) -> Option<Rectangle>

Rectangle currently occupied by the focusable target, if any.

fn focus_at(&self, point: Point) -> Option<WidgetId>

Focusable widget id at point, if any.
