Defining classes
In the Smalltalk development environment, you generally define a class (or create a defined class) by subclassing from an existing class.
Defining a class consists of the following activities:
You must specify a containing application for the class.
You must be a group member of this application.
You must give the class a unique name. No two classes in your image can have the same name.
When you create a class, you become its owner.
