A part code indicating the manner in which the scrolling should be performed.
Declaration
var hitPart: NSScroller.Part { get }Discussion
This method is typically invoked by an NSScrollView object to determine how to scroll its document view when it receives an action message from the scroller.
See NSScroller.Part for a list of part codes. In macOS 10.7 and later, this method no longer returns NSScroller.Part.incrementLine or NSScroller.Part.decrementLine.
