Struct DragDropEngine 

pub struct DragDropEngine(/* private fields */);

The <perspective-viewer> drag/drop service, which manages drag/drop user interactions across components. It is a component-level service, since only one drag/drop action can be executed by the user at a time.

Implementations

impl DragDrop

pub fn new(elem: &HtmlElement) -> Self

impl DragDrop

pub fn to_props(&self) -> DragDropProps

Snapshot the drag state as a [DragDropProps] value for threading through the component tree without PubSub subscriptions.

pub fn get_drag_column(&self) -> Option<String>

Get the column name currently being drag/dropped.

pub fn get_drag_target(&self) -> Option<DragTarget>

pub fn set_drag_image(&self, event: &DragEvent) -> ApiResult<()>

pub fn is_dragover(&self, drag_target: DragTarget) -> Option<(usize, String)>

pub fn notify_drop(&self, event: &DragEvent)

pub fn notify_drag_start(&self, column: String, effect: DragEffect)

Start the drag/drop action with the name of the column being dragged.

pub fn notify_drag_end(&self)

End the drag/drop action by resetting the state to default.

pub fn notify_drag_leave(&self, drag_target: DragTarget)

Leave the action zone.

pub fn notify_drag_enter(&self, target: DragTarget, index: usize) -> bool

Trait Implementations

impl Clone for DragDrop

fn clone(&self) -> DragDrop

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Deref for DragDrop

type Target = Rc<DragDropState>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl ImplicitClone for DragDrop

fn implicit_clone(&self) -> Self

This function is not magic; it is literally defined as

impl PartialEq for DragDrop

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
