Struct DropRegionSpec 

pub struct DropRegionSpec { /* private fields */ }

Per-region configuration for a multi-zone DropTarget: an optional hint plus a reactive enabled flag. Kept as a struct so more per-zone knobs can land without a signature churn.

Implementations

impl DropRegionSpec

pub fn new() -> Self

An enabled spec with no hint.

pub fn hint(self, widget: impl Widget + 'static) -> Self

Widget shown (centered in this region’s rect, inside a popup card) while a drag with an accepted payload hovers this region.

pub fn hint_id(self, id: WidgetId) -> Self

This region’s hint content by pre-registered WidgetId.

pub fn enabled(self, enabled: impl Into<Prop<bool>>) -> Self

Whether this zone is active — static or signal-bound (default true). A bound Signal<bool> enables/disables the zone live, without a rebuild: while disabled the zone stops hit-testing (its area falls through to the next-priority enabled zone, or Center, or rejects), never highlights, and never shows its hint. The enabled state is resolved on every drag tick, so a .set(false) mid-drag takes effect on the next hover.

Trait Implementations
