Comment on "NSTreeController and Drag and Drop"
by Matt Holiday — Aug 21
I've written an extension to the OutlineEdit Core Data example (named DragAndDropOutlineEdit) which supports cut/copy/paste and drag-n-drop and gets a bit deeper into the opaque objects behind the tree controller. It also shows how to copy & paste portions of a managed object graph (via relationships), not just "flat" attributes of a managed object.
