NSControl is a subclass of NSView that is the base class of all AppKit controls like text fields (NSTextField), buttons (NSButton), table views (NSTableView), color wells (NSColorWell), and more. Controls generally have associated cells that are responsible for presenting the graphical appearance of the control, and responding appropriately to user interaction with the control.
