Practical Smalltalk (PDF)

Object-Oriented Programming (OOP) is recognized as one of the most powerful programming techniques to come along in many years. Its power lies in the ability it gives the designer to manage the complex, rapidly changing applications that have become the watchword of modern software. Smalltalk is the most extensively used OOP environment. Now Practical Smalltalk helps you to focus on those aspects of the language that you need to know to be a successful programmer. You'll learn all about the important classes to master, the essential theories to grasp, and then put these ideas to work in constructing everything from a simple counter object all the way through a data graphing application and the core of a functional outliner. The book culmi- nates with the creation of a factory process simulation that takes advantage of Smalltalk's ability to create multi-window, multiprocessing applications. Designed for programmers and managers who must understand the operation and uses of the Smalltalk environment, this book assumes only an elementary working knowledge of OOP and the language. The book uses Smalltalk/V 286, Digitalk's widely used implementation of Smalltalk, but most of the concepts and techniques it teaches can be transferred easily to other versions of the language.
