NSDraggingInfoMBS class

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
class Drag & Drop MBS MacCocoa Plugin 13.1 Yes No No Yes, macOS only No
Function: The NSDraggingInfo protocol declares methods that supply information about a dragging session.
Notes: NSDraggingInfo protocol methods are designed to be invoked from within a class's implementation of NSDraggingDestination protocol methods. The Application Kit automatically passes an object that conforms to the NSDraggingInfo protocol as the argument to each of the methods defined by NSDraggingDestination. NSDraggingInfo messages should be sent to this object; you never need to create a class that implements the NSDraggingInfo protocol.
