Instance Method

setDraggingSourceOperationMask(_:forLocal:)

Configures the default value returned from draggingSourceOperationMaskForLocal:.

Declaration

func setDraggingSourceOperationMask(_ dragOperationMask: NSDragOperation, forLocal localDestination: Bool)

Parameters

dragOperationMask: The types of drag operations allowed.
localDestination: If true, mask applies when the drag destination object is in the same application as the receiver; if false, mask applies when the destination object is outside the receiver’s application.

Discussion

By default, this method returns every when localDestination is true and none when localDestination is false. NSCollectionView will save the values you set for each localDestination value.

You typically will invoke this method, and not override it.
