Declaration

public delegate DragAndDropVisualMode HierarchyDropHandler(int dropTargetInstanceID, HierarchyDropFlags dropMode, Transform parentForDraggedObjects, bool perform);

Parameters

dropTargetInstanceID ID of the Game Object in the Hierarchy window that is under the mouse cursor.
parentForDraggedObjects The parentForDraggedObjects is only set under special situations in Prefab Mode (most often it will be null). If this value is set the dropTargetInstanceID is 0. And the client code should use 'parentForDraggedObjects' as a forced parent of the drag.
perform True if the event is of type EventType.DragPerform.
dropMode Specify how the dragged object is to be dropped in the Hierarchy window.

Returns

DragAndDropVisualMode Returns DragAndDropVisualMode.None if this handler is not able to process event. In that case a new handler will be called for processing. Any other DragAndDropVisualMode results will stop the handler chain.

Description

Handler for the Hierarchy.
