Introduction

This alphabetical presentation of the classes in the XVT-Power++ class hierarchy is designed as a convenient reference for specific information on XVT-Power++'s structure and functionality. It offers a description of each class and its methods and data members, including the protected and private ones. It is targeted towards two groups of readers:

Programmers who want to use XVT-Power++ as an interface for writing portable graphical applications. This group is more interested in how XVT-Power++ works and how it can be used than in implementation details.
Developers who want to override some XVT-Power++ classes and write new ones. This group needs information about internals (protected and private information) and may need specifics on how the XVT Portability Toolkit and XVT-Power++ are connected.

We assume that you have some basic knowledge of GUI features and programming, a working knowledge of C++, and access to the XVT Portability Toolkit documentation.

We have sought to minimize the need to refer to the XVT Portability Toolkit Release 5 manual and thus show the XVT Portability Toolkit definitions where appropriate. We include tables of the XVT Portability Toolkit options that are pertinent to various classes-for environment settings, window types, unsigned attributes, and so on. Also with convenience in mind, we have chosen to minimize cross- references and to make each discussion of a class as complete and independent as possible. The result is a lot of repetition, but you can find almost everything you need to know about a given class in one place. The discussion of each class includes the following:

A description of the class and its usage
A descriptive listing of its data members
Descriptions of methods specific to the class
Descriptions of methods that are inherited and overridden
An index of methods that are inherited but not overridden, with hypertext links to descriptions of each method

Tables of Contents

This reference documents the DSC++ public interface alphabetically, class-by-class. To locate a class, use the "XVT-Power++ Classes" contents page, which lists all classes, or the "New Classes for Release 5" page, which lists only new classes. When you click a class name, you will go to an individual hypertext table of contents for that class.

At the end of the reference, you will find an "Index of Methods." (Note: you can access the index at any time by using the Navigation Bars at the beginning and end of every file.) If you already know the name of a method, use this index to find it. Or if you are looking for a particular kind of function, use your browser's search capability. For example, if you want to know what methods involve the use of color, go to the methods index and enter the word "color" in the search (or "find") dialog box.

Each class also has its own methods index, including all methods inherited (when applicable) but not overridden. To access the index for a class, simply click the "Methods Index" box at the beginning of the class table of contents. If the class has a parent, you will see a table of contents where you can choose whether to list the class methods or the methods of its ancestor(s).
