Struct DragAndDropState 

pub struct DragAndDropState { /* private fields */ }

The one transfer in flight in an app context, the targets attached in it, and the steps the source recorded since the shell last routed.

Implementations

impl DragAndDropState

pub fn is_target(&self, node: NodeId) -> bool

Whether node carries a drag_and_drop_target right now.

pub fn is_active(&self) -> bool

Whether a transfer is in flight.

pub fn route( &self, find_target: impl FnMut(DragAndDropPoint) -> Option<(NodeId, Point)>, ) -> bool

Delivers every step recorded since the last call. find_target names the target node under a point and the point in that node’s surface; the shell answers it from its surfaces and their positions on the screen. Returns whether anything was delivered.

Trait Implementations

impl Default for DragAndDropState

fn default() -> Self

Returns the “default value” for a type.
