The AddBookForm, created in the painter, is displayed as a class in the Class Browser.
If you select the AddBookForm, a list of its controls is displayed in the central properties window.
You can add properties and methods for the AddBookForm in the same way you did for the Book and Borrower classes.
Because AddBookForm is a subclass of the JADE system class Form, it inherits a vast amount of functionality.
Each class in the Class Browser has a small yellow icon to the left of the class name.
The meaning of the icons is described below
 Subclasses exist but are not displayed.

 Subclasses exist and are displayed.
