The text within each view can have separate layout and selections. Multiple layout managers allow you to have multiple presentations of the same text. The text within each view can have separate layout and selections. With one text view, all of the text flows within a single, typically recutangular, area. As text is added, it fills the recion defined by the first text containers. The text is displayed in the text view that is paired with the text container. When there’s no ⾭ more room, another text container (and associated text view) is added, and the text flows onto the second page. CBTJD NVMUJDPOUBJOFST NVMUJMBZPVU.BOBHFST

NSText objects are used by the Application Kit wherever text appears in interface objects: An NSText object draws the title of a window, the commands in a menu, the title of a button, and the items in a browser. Your application inherits these uses of the NSText class when it incorporates any of these objects into its interface. Your application can also create NSText objects for its own purposes. The NSText class is unlike most other classes in the Application Kit in its complexity and range of features. One of its design goals is to provide a comprehensive set of text-handling features so that you’ll rarely need to create a subclass. An NSText object can (among other things): • Control the color of its text and background. • Control the font and layout characteristics of its text. /45FYU
