“wxPython in Action” is a complete guide to the wxPython toolkit, containing a tutorial for getting started, a guide to best practices, and a reference to wxPython’s extensive widget set. After an easy introduction to wxPython concepts and programming practices, the book takes an in-depth tour of when and how to use the bountiful collection of widgets offered by wxPython. All features are illustrated with useful code examples and reference tables are included for handy lookup of an object’s properties, methods, and events. The book enables developers to learn wxPython quickly and remains a valuable resource for futurework.
