Struct LaidOutWidget

pub struct LaidOutWidget<Msg: Clone> {
    pub rect: Rect,
    pub flat_idx: usize,
    pub id: Option<WidgetId>,
    pub paint_rect: Rect,
    pub handlers: WidgetHandlers<Msg>,
    pub keyboard_focusable: bool,
    pub cursor: CursorShape,
    pub tooltip: Option<String>,
    pub accessible_label: Option<String>,
    pub is_live_region: bool,
}

Result of laying out one interactive widget — i.e. a widget that should receive pointer / touch hit-testing. Captures both the hit rect (where input lands) and the paint rect (the bounding box of everything the widget actually paints, including hover circles, focus rings, shadows…). The paint rect is used by the partial-redraw path to know how much of the canvas must be invalidated when a widget transitions in/out of a given state — it is always >= rect.

handlers carries the snapshot of the widget’s callbacks/values at layout time so input dispatch is O(1) instead of re-walking the super::Element tree.

keyboard_focusable snapshots whether the widget should participate in the Tab / Shift+Tab cycle. Most interactive widgets are also keyboard-focusable (Button, TextEdit, Slider, …) but window-decoration chrome (WindowButton) is interactive without taking keyboard focus by default — matching the convention of macOS / GNOME / Windows title bars.

Fields

rect: Rect

flat_idx: usize

id: Option<WidgetId>

paint_rect: Rect

handlers: WidgetHandlers<Msg>

keyboard_focusable: bool

cursor: CursorShape

Cursor shape this widget wants to show on hover. Snapshotted from super::Element::cursor_shape at layout time so the input dispatch can pick the right shape without re-walking the element tree.

tooltip: Option<String>

accessible_label: Option<String>

Visible text of the widget, captured for the accessibility tree. None for non-textual widgets (icons, dividers).

is_live_region: bool
