Cross-Platform GUI Programming with wxWidgets
wxWidgets has its own 700-page book to help you learn or brush up on your cross-platform programming skills. Written by Julian Smart and Kevin Hock with Stefan Csomor, "Cross-Platform GUI Programming with wxWidgets" was published on July 27th 2005 by Prentice Hall as part of Bruce Perens' Open Source Series.
The book comes packed with useful information and samples. The accompanying CD-ROM contains source code, compilers and tools, and includes DialogBlocks, a powerful dialog editor for Windows, Linux and Mac OS X which will also help you compile your applications and wxWidgets itself.
"Cross-Platform GUI Programming with wxWidgets is the best way for beginning developers to learn wxWidgets programming in C++, and is a valuable resource for experienced wxWidgets programmers looking to expand their skills. This book is a must-have both for programmers thinking of using wxWidgets and for those already using it."
Mitch Kapor, founder of Lotus Software and the Open Source Applications Foundation
Please note: From feedback we're getting, it's easy to miss the setup instructions in Appendix B and Appendix C that tell you how to build your own applications using popular compilers. In particular, you should find that DialogBlocks (included on the accompanying CD-ROM) is a quick way to get started, compiling both the wxWidgets library and your own first wxWidgets applications.
