Object-Oriented Design

Abstract

The aim of this book is to show how the object-oriented design process can be used in the development of programs which are then written in C++. One of the best ways of explaining a technique is to use an appropriate example, and this is provided by the drawing package. Therefore in this chapter the design of the package is given. This requires a knowledge of the facilities provided by the package, so these are described first. The overall design of the program is given next, by first identifying the objects appropriate to the application. The structure of the program is then decided, and the objects in each part are considered in more detail. This introduces a number of useful techniques which are expanded upon in later chapters, so references to these chapters are given. The way in which the program was developed and tested is also described.
