NSDraggingInfo Mac OS X 10.0

This protocol declares methods that are used to provide an interface to objects that represent dragging sessions. When a dragging session begins, an object that conforms to this protocol is automatically created, and is the sender of all messages to the destination object, which implements the methods outlined in the NSDraggingDestination protocol. NSDraggingInfo exists to publish the interface for this object that represents the dragging operation, and as such developers never need to implement these methods.
