Declaration
class NSPathControlOverview
The NSPathControl class uses NSPathCell to implement its user interface. NSPathControl provides cover methods for most NSPathCell methods—the cover method simply invokes the corresponding cell method. See also NSPathComponentCell, which represents individual components of the path, and two associated protocols: NSPathCellDelegate and NSPathControlDelegate.
NSPathControl has three styles represented by the NSPathControl.Style enumeration constants NSPathControl.Style.standard, NSPathStyleNavigationBar, and NSPathControl.Style.popUp. The represented path can be a file system path or any other type of path leading through a sequence of nodes or components, as defined by the programmer.
NSPathControl automatically supports drag and drop, which can be further customized via delegate methods. To accept drag and drop, NSPathControl calls registerForDraggedTypes(_:) with NSFilenamesPboardType and NSURLPboardType. When the URL value in the NSPathControl object changes because of an automatic drag and drop operation or the user selecting a new path via the open panel, the action is sent. In OS X v10.5 the value returned by clickedPathComponentCell() is nil, in macOS 10.6 and later, clickedPathComponentCell() returns the clicked cell.
