RectWidget

RectWidget — a leaf widget that paints a filled and/or stroked rounded rectangle.

RectWidget has no intrinsic content: it fills whatever space its parent proposes (or reports 0×0 when unconstrained) and draws a fill (solid color or gradient), an optional border (a uniform stroke positioned inside / center / outside, or per-side edge fills for an underline), and an optional corner radius. It is the low-level building block for card backgrounds, focus rings, dividers, underlined fields, and highlight overlays.

The fill accepts impl Into<PaintProp> — anything Into<ColorProp> (a raw Color, a theme role such as SurfaceRole::Hover, or a Signal<Color>) for a solid, plus PaintProp::Linear / Radial for a gradient. Border color accepts impl Into<ColorProp>, so reactive interaction-driven colors require no extra wiring.

API reference

📖 Full rustdoc API for this module

pub struct RectWidget

A leaf widget that paints a filled and/or stroked rounded rectangle.

See the module documentation for the full feature description. All visual properties accept impl Into<ColorProp> (colors/roles/signals) or impl Into<Prop<f32>> / impl Into<Prop<CornerRadius>> (static or reactive) — so the common "fill with theme surface, border with theme border" setup is just .background(SurfaceRole::Main).border_color(BorderRole::Default).

fn main() {
pub struct RectWidget { /* fields */ }
}

Methods

pub fn new() -> Self

Create a fully transparent, zero-border rectangle with no corner radius.

pub fn background(mut self, paint: impl Into<PaintProp>) -> Self

Fill. Accepts Color, a theme role (SurfaceRole, etc.), a Signal<Color>, or a PaintProp (e.g. a gradient).

pub fn border_sides(mut self, sides: impl Into<Prop<Option<BorderSides>>>) -> Self

Per-side border widths (e.g. BorderSides::bottom for an underline). When set, overrides the uniform stroke; sides are drawn as edge fills in border_color.

pub fn border_position(mut self, position: BorderPosition) -> Self

Where a uniform stroke sits relative to the rect edge (inside / center / outside). Ignored when border_sides is set.

pub fn border_color(mut self, color: impl Into<ColorProp>) -> Self

Border color. Accepts Color, a theme role (BorderRole, etc.), or a Signal<Color>.

pub fn border_width(mut self, width: impl Into<Prop<f32>>) -> Self

Stroke width, in logical pixels. Accepts a static value or a reactive Signal<f32>.

pub fn corner_radius(mut self, radius: impl Into<Prop<CornerRadius>>) -> Self

Corner radius for the fill and stroke. Accepts a CornerRadius (per-corner control) or a reactive Signal<CornerRadius>.
