The authoritative guide to developing cross-platform C++ GUI applications using the hot wxWidgets toolkit -- from its creator!

° As Mac OS X and Linux gain share, wxWidgets is emerging as the best crossplatform

GUI toolkit.

° Better than MFC - the creator of wxWidgets shows readers how to build C++

applications that support Windows, Linux and Mac OS X - prior GUI programming

experience is not required.

"This book is the best way for beginning developers to learn wxWidgets programming in C++. It is a must-have for programmers thinking of using wxWidgets and those already using it."

–Mitch Kapor, founder of Lotus Software and the Open Source Applications Foundation

  • Build advanced cross-platform applications that support native look-and-feel on Windows, Linux, Unix, Mac OS X, and even Pocket PC

  • Master wxWidgets from start to finish–even if you've never built GUI applications before

  • Leverage advanced wxWidgets capabilities: networking, multithreading, streaming, and more

  • CD-ROM: library of development tools, source code, and sample applications

  • Foreword by Mitch Kapor, founder, Lotus Development and Open Source Application Foundation

wxWidgets is an easy-to-use, open source C++ API for writing GUI applications that run on Windows, Linux, Unix, Mac OS X, and even Pocket PC–supporting each platform's native look and feel with virtually no additional coding. Now, its creator and two leading developers teach you all you need to know to write robust cross-platform software with wxWidgets. This book covers everything from dialog boxes to drag-and-drop, from networking to multithreading. It includes all the tools and code you need to get great results, fast. From AMD to AOL, Lockheed Martin to Xerox, world-class developers are using wxWidgets to save money, increase efficiency, and reach new markets. With this book, you can, too.

Untitled Document


This book is a guide to using wxWidgets: an open-source construction kit to help you write sophisticated C++ applications for a variety of platforms, including Windows, Linux, Mac OS X, and Pocket PC. With help from this book, a competent programmer can create multi-platform applications with confidence. Developers already familiar with wxWidgets should also find it useful for brushing up their knowledge.

This book is accessible to developers with a variety of experience and backgrounds. You may come from a Windows or Unix perspective; you may previously have experience in MFC, OWL, Win32™, Mac OS, Motif™, or console-mode Unix programming. Or perhaps you have come from a different career entirely and are looking for a way to get up to speed on multiple platforms. The book can't specifically cover the details of the C++ language, but it's common for people to successfully learn C++ and wxWidgets at the same time, and the straightforward nature of the wxWidgets API makes it easier. The reader does not need to know more advanced C++ techniques like templates, streams and exceptions. However, wxWidgets does not prevent you from using these techniques.

Managers will find the book useful in discovering what wxWidgets can do for them, particularly in Chapter 1. The combination of the book and the resources on the accompanying CD-ROM will give your staff all they need for getting started on cross-platform programming projects. You'll see how wxWidgets puts tools of tremendous power into your hands, with benefits that include:

  • Cost savings from writing code once that will compile on Windows, Unix, Mac OS X and other platforms.

  • Customer satisfaction from delivering stable, fast, attractive applications with a native look and feel .

  • Increased productivity from the wide variety of classes that wxWidgets provides, both for creating great GUIs and for general application development.

  • Increased market share due to support for platforms you may not have previously considered, and the ability to internationalize your applications.

  • Support from a large, active wxWidgets community that answers questions helpfully and provides prompt bug-fixing. The sample of third-party add-ons listed in Appendix E is evidence of a thriving ecosystem.

  • Access to the source , for enhancement and trouble-shooting.

This is a guide to writing wxWidgets application with C++, but you can use a variety of other languages such as Python, Perl, a BASIC variant, Lua, Eiffel™, JavaScript, Java™, Ruby, Haskell and C#™. Some of these bindings are more advanced than others. For more information, please see Appendix E and the wxWidgets web site at:


We focus on three popular desktop platforms: Microsoft Windows, Linux using GTK+, and Mac OS X. However, most of the book also applies to other platforms supported by wxWidgets. In particular, wxWidgets can be used with most Unix variants.


The CD-ROM contains example code from the book, the wxWidgets 2.6 distribution for Windows, Linux, Mac OS X and other platforms, and several tools to help you use wxWidgets, including the translation tool poEdit. For Windows users, we supply two free compilers you can use with wxWidgets: MinGW and Digital Mars C++.

In addition, we provide you with DialogBlocks Personal Edition, a sophisticated rapid application development (RAD) tool for you to create complex windows with very little manual coding. You can use it to compile and run samples that accompany the book as well as create your own applications for personal use, and it also provides convenient access to the wxWidgets reference manual.

Updates to the book and CD-ROM can be obtained from this site:



It's advisable to read at least Chapters 1 through 10 in order, but otherwise you'll probably read the chapters you need to complete a particular task. If you haven't installed wxWidgets before, you may wish to look at Appendix A, Installing wxWidgets early on. MFC programmers will find it useful to read Appendix K, Porting from MFC as a point of reference.

Because this book is not a complete API reference, you'll find it useful to keep the wxWidgets Reference Manual open. The reference manual is available in a number of formats including Windows HTML Help and PDF, and is either in your wxWidgets distribution or can be downloaded from the wxWidgets web site. You can also refer to the many samples in the wxWidgets distribution to supplement the examples given in this book.

Note that the book is intended to be used in conjunction with wxWidgets 2.6 or later. The majority of the book will apply to earlier versions, but be aware that some functionality will be missing, and in a small number of cases, the behavior may be different. In particular, sizer behavior changed somewhat between 2.4 and 2.5. For details, please see the topic Changes since 2.4.x in the wxWidgets reference manual.


For code examples, we mostly follow the wxWidgets style guidelines, for example:

  • Words within class names and functions have an initial capital, for example MyFunkyClass .

  • The "m_" prefix denotes a member variable, "s_" denotes a static variable, "g_" denotes a global variable; local variables start with a lower case letter, for example textCtrl .

You can find more about the wxWidgets style guidelines here:


Sometimes we'll also use comments that can be parsed by the documentation tool Doxygen, such as:

/// A function description

Classes, functions, identifiers and standard wxWidgets objects are marked with a teletype font in the text, and variables are italicised . User interface commands, such as menu and button labels, are also italicised.
