Cocoa in a Nutshell

Name

NSDraggingSource — Mac OS X 10.0

Synopsis

This informal protocol declares methods that a class must implement to serve as a source of data in dragging operations. This protocol declares a number of methods, but classes need only implement the method draggingSourceOperationMaskForLocal: to be a valid dragging operation source. Classes should implement this method to return a dragging source operation mask, which describes how data should be handled in a dragging operation. See NSDraggingInfo’s listing (previously) for more information.
