wxWidgets was started in 1992 by Julian Smart at the University of Edinburgh. Initially started as a project for creating applications portable across Unix and Windows, it has grown to support the Mac platform, WinCE, and many other toolkits and platforms. The number of developers contributing to the project is now in the dozens and the toolkit has a strong userbase that includes everyone from open source developers to corporations such as AOL. So what is special about wxWidgets compared with other cross-platform GUI toolkits?
wxWidgets gives you a single, easy-to-use API for writing GUI applications on multiple platforms that still utilize the native platform's controls and utilities. Link with the appropriate library for your platform (Windows/Unix/Mac, others coming shortly) and compiler (almost any popular C++ compiler), and your application will adopt the look and feel appropriate to that platform. On top of great GUI functionality, wxWidgets gives you: online help, network programming, streams, clipboard and drag and drop, multithreading, image loading and saving in a variety of popular formats, database support, HTML viewing and printing, and much much more.
wxWidgets now 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. It's part of Bruce Perens' Open Source Series.
