Adding a superclass using drag-and-drop
You can also add a superclass using drag-and-drop:
  1. Select Editor in the Class Browser.

  2. Hold down the mouse button and drag the Editor class over Employee. Employee is outlined.

  3. Before releasing the mouse button, hold down the Ctrl key, then release the mouse button to drop the subclass.


To remove a superclass from a class, highlight the superclass you want to remove in the Superclasses pane and click the Remove Superclass button. You are now ready to assign some attributes to the classes you have created, by creating slots, which are covered in the next section.
