Hi, I tried using concludeDragOperation method, but for some reason, it is not getting called.
I did the following: 1. I created a controller which has a table view that serves as a drag/ drop source. Registered for the dragged types: NSTabularTextPboardType and NSStringPboardType Implemented the drag/ drop methods in the controller. 2. Created a subclass of NSTextField. Implemented the methods, draggingEntered, draggingExited, performDragOperation, concludeDragOperation, prepareForDragOperation in this class. 3. The drag/ drop destination is another controller, in which the text field exists as an outlet (of type custom class of NSTextField) Now, when i drag and drop from table view onto the text field, draggingEntered, draggingExited methods are called, where as the performDragOperation, concludeDragOperation are not getting called. Could you please tell me if i am missing something here?
