Struct DropZone 

pub struct DropZone<T: 'static + PartialEq + Clone> { /* private fields */ }

A container that receives the payload of a DragZone released over it.

Example

fn app() -> impl IntoElement {
    DropZone::new(|data: usize| println!("Dropped {data}")).child("Drop here!")
}

Implementations

impl<T: PartialEq + Clone + 'static> DropZone<T>

pub fn new(on_drop: impl Into<EventHandler<T>>) -> Self

Create a drop zone, on_drop is called with the payload of the released DragZone.

pub fn on_drag_over(self, on_drag_over: impl Into<EventHandler<bool>>) -> Self

Called with true when a drag enters this zone and false when it leaves or is dropped. Only fires while a drag of T is in progress, so it is handy for showing drop previews.

Trait Implementations

impl<T: Clone + PartialEq + 'static> ChildrenExt for DropZone<T>

fn children_mut(&mut self) -> &mut Vec<Element>

Returns a mutable reference to the internal children vector.

fn children(self, children: impl IntoIterator<Item = impl IntoElement>) -> Self

Extends the children with an iterable of anything that implements IntoElement.

fn maybe_child<C>(self, child: Option<C>) -> Self

where C: IntoElement,

Appends a child only when the Option is Some.

fn child<C>(self, child: C) -> Self

where C: IntoElement,

Appends a single child element.

impl<T: Clone + 'static + PartialEq + Clone> Clone for DropZone<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Clone + PartialEq + 'static> Component for DropZone<T>

fn render(&self) -> impl IntoElement

fn render_key(&self) -> DiffKey

impl<T: Clone + PartialEq + 'static> ContainerExt for DropZone<T>

fn padding(self, padding: impl Into<Gaps>) -> Self

Set the inner spacing between the element’s edges and its content. See Gaps.

impl<T: Clone + PartialEq + 'static> KeyExt for DropZone<T>

fn key_mut(&mut self) -> &mut DiffKey

Returns a mutable reference to the element’s diff key.

fn key(self, key: impl Hash) -> Self

where Self: 'static,

Assign a key derived from any hashable value, used to reconcile elements in dynamic lists. The key is scoped to the element’s type, so the same value used on different element or component types never collides.

impl<T: Clone + PartialEq + 'static> LayoutExt for DropZone<T>

fn layout_mut(&mut self) -> &mut LayoutData

Returns a mutable reference to the element’s layout data.

fn layout(self, layout: LayoutData) -> Self

Replace all of the element’s layout data at once. See LayoutData.

impl<T: PartialEq + 'static + PartialEq + Clone> PartialEq for DropZone<T>

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
