Appearance

Interface: DropTargetHandlers ​

Defined in: packages/sdk/src/dnd-service.ts:101

Handlers for a target registered via DndService.registerDropTarget.

Properties ​

accepts ​

ts
accepts: string[];

Defined in: packages/sdk/src/dnd-service.ts:103

MIME types this target consumes; a drag is accepted if it carries one.

capture? ​

ts
optional capture?: boolean;

Defined in: packages/sdk/src/dnd-service.ts:126

Attach listeners in the capture phase so this target intercepts before bubble-phase handlers (e.g. the center dock). Defaults to false.

Methods ​

onDrop() ​

ts
onDrop(ctx): boolean | void;

Defined in: packages/sdk/src/dnd-service.ts:109

Called on a matching drop. Return true if you handled it — the host then calls preventDefault() + stopPropagation() so the drop does not fall through to other targets (e.g. the center dock opening a new pane).

Parameters ​

ctx ​

DropContext

Returns ​

boolean | void

onDragOver()? ​

ts
optional onDragOver(ctx): void | "copy" | "move" | "none";

Defined in: packages/sdk/src/dnd-service.ts:115

Optional: called on each accepted drag-over (drive hover styling). Return a drop effect to set the cursor, or nothing to leave it. The host already calls preventDefault() so the drop is allowed.

Parameters ​

ctx ​

DropContext

Returns ​

void | "copy" | "move" | "none"

onDragLeave()? ​

ts
optional onDragLeave(e): void;

Defined in: packages/sdk/src/dnd-service.ts:121

Optional: the pointer left the target (clear hover styling). Receives the native event so callers can ignore leaves into a descendant (el.contains(e.relatedTarget)).

Parameters ​

e ​

DragEvent

Returns ​

void
