Struct Domain 

pub struct Domain<R, I>(/* private fields */);

Gesture and animation state for the regions items move between.

Implementations

impl<R: Clone + PartialEq + 'static, I: Clone + PartialEq + 'static> Domain<R, I>

pub fn new() -> Self

The carried item is painted in place, following the pointer.

pub fn with_ghost( ghost: impl Fn(&I, &mut Window, &mut App) -> AnyElement + 'static, ) -> Self

The carried item’s own element stays hidden in its slot and gpui paints ghost under the pointer instead. For virtualized regions, where the item’s element can scroll out of the painted range.

pub fn region( &self, element_id: impl Into<ElementId>, id: R, axis: Axis, child: impl IntoElement, ) -> Region<R, I>

A drop target laid out by the host. child holds this region’s handles.

pub fn handle<E>(&self, item: I, element: E) -> Handle<R, I>

where E: StatefulInteractiveElement + IntoElement + 'static,

Makes element pickable as item by putting on_drag on it, so element must not have one of its own. Item ids are unique within a domain. Custom controls inside it stop mouse-down propagation to keep their presses from starting a drag.

pub fn fixed(&self, item: I, element: impl IntoElement) -> Handle<R, I>

An item that is measured and moves aside like a handle but cannot be picked up, such as a heading between sections.

pub fn carries(&self, item: &I) -> bool

Whether item is being carried.

pub fn cancel(&self, window: &mut Window, cx: &mut App)

Ends the gesture without a drop. escape does the same while an item is carried.

pub fn carried(&self) -> Option<I>

The item being carried.
