Implementations

impl<'cx, G: Html, T: FromTransfer + 'static> DroppableBuilder<'cx, G, T>

pub fn on_drop(self, f: impl Fn(T) + 'cx) -> Self

Sets a callback to run when an item is dropped on this droppable element. The argument is parsed from the item’s DataTransfer.

pub fn accept(self, f: impl Fn(&T) -> bool + 'cx) -> Self

A callback to check if the incoming DataTransfer should be accepted. The argument is parsed from the item’s DataTransfer.

pub fn hovering_class(self, class: impl Into<String>) -> Self

A class or list of classes to set when a valid item is hovering over the element. They are automatically removed when the item leaves or is dropped.

pub fn node_ref(self, node_ref: &'cx NodeRef<G>) -> Self

An existing [NodeRef] to use instead of creating a new one. Useful for combining drag and drop on one element, or using your own logic that requires [NodeRef].

pub fn build(self) -> &'cx NodeRef<G>

Create the droppable logic. Returns a [NodeRef] that needs to be set as the element’s ref attribute.
