Question

Consider a view (parent) with a subview (child). Both have registered for the dragged type NSFilenamesPboardType.

parent is only interested in image files and child in audio files. If they detect a file of the corresponding type in draggingEntered: they return NSDragOperationCopy. If not, they return NSDragOperationNone.

child overlaps parent and when a drag reaches child, parent receives a draggingExited: message, no matter if child is interested in the drag or not.

How can I make parent receive the drag if child does not want it?

Answer 1

If I get this right you should call:

[self.superview yourmethod];

in the childs function.

If the child inherited from the parent you can call:

[super yourmethod];
