Struct Menu 

pub struct Menu {
    pub min_width: f32,
    pub row_height: f32,
    pub font_size: Option<f32>,
    pub radius: f32,
    /* private fields */
}

A vertical list of pressable rows — the standard dropdown content.

Pair with OverlayApi::dropdown, which anchors it below the trigger:

Button::new("File")
    .dropdown(open.clone(), move || Box::new(
        Menu::new()
            .item("New",  { let o = open.clone(); move || { o.set(false); /* … */ } })
            .item("Open", { let o = open.clone(); move || { o.set(false); /* … */ } })
    ))

Fields

min_width: f32

row_height: f32

font_size: Option<f32>

None = read from the active theme’s typography.body_medium (D127 “environment” track — see Checkbox::resolved_font_size’s doc for the reasoning).

radius: f32

Implementations

impl Menu

pub fn new() -> Self

pub fn min_width(self, w: f32) -> Self

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

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

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

Menu surface fill color (theme’s surface if unset).

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

Item label color (theme’s on_surface if unset).

pub fn item( self, label: impl Into<String>, f: impl Fn() + Send + Sync + 'static, ) -> Self

Append a pressable row. The callback fires on click; close the menu yourself by setting the open atom false inside it.

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

Record draw commands for ctx.rect.
