Generic UI Controllers: 3 Using Controllers

There are essentially two ways to use controller objects: The first, and the simplest, is to simply include an object of an existing controller class and the data object for which it's designed (e.g. using a PointSizeControl object with a GenText object). The second, and quite more complex, is to create either your own data objects or your own controllers.

This section describes the basic components of a controller object on the most general level--how to include a pre-existing controller along with its data object. For full information on how the GenControlClass works and how a data object interacts with it, see Creating Your Own Controllers . This section focuses on how you can use a controller object; nearly all of this will be academic if you use a GenToolControl object in your application.
