Class

NSActionCell

An active area inside a control.

Overview

An NSActionCell does three things: it displays text or an icon; it provides the target object and action method used by its NSControl object; and it handles mouse (cursor) tracking by properly highlighting its area and sending action messages to its target based on cursor movement.
