In Detail

In today’s world of desktop applications there is a great amount of incentive to be able to develop applications that can run in more than one environment. Currently there are a handful of options available for cross platform frameworks to develop desktop applications in Python. wxPython is one such cross- platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a complete, highly functional graphical user interface, simply and easily. wxPython code style has changed quite a bit over the years, and gotten much more Pythonic. The examples you will find in this book are right up to date and reflect this change in style.
This cookbook provides you with the latest recipes to quickly create robust, reliable, and reusable wxPython applications. These recipes will guide you from writing simple, basic wxPython scripts all the way through complex concepts, and also feature various design approaches and techniques in wxPython.

The book starts off by covering a variety of topics from the most basic requirements of a wxPython application to some of the more in depth details of the inner workings of the framework laying the foundation for any wxPython application. It then explains event handling, basic and advanced user interface controls, designing and layout, creating dialogs, components and extending functionality, and so on. We conclude by learning how to build and manage applications for distribution.
For each of the recipes, there is an introductory example, then more advanced examples, and plenty of example code to develop and manage user-friendly applications. For more experienced developers, most recipes also include additional discussion of the solution, allowing you to further customize and enhance the component.
