This class is the base superclass for the hierarchy of lightweight objects that know how to draw into a view. Most NSControl classes in the Application Kit defer the implementation of drawing to an associated NSCell. For example, NSButton uses a concrete subclass of NSCell, NSButtonCell, to handle all of the drawing and event handling of a button interface component. Cells provide a leaner alternative to using views in situations when a control appears repeatedly in a view. The interface of NSCell is closely mirrored in NSControl; indeed, many concrete subclasses of NSControl forward most messages to their associated NSCell object.
