About the Book

Creating GUI Applications with wxPython is a book that will teach you how to use wxPython to create applications by actually creating several mini-programs. I have found that while learning how the various widgets work in wxPython is valuable, it is even better to learn by creating a simple application that does something useful.

Note that this book is not for people who are completely unfamiliar with GUIs. While you can probably figure wxPython out using this book, you'll be better off starting with a wxPython tutorial or two and then reading this book.

In this book, you will be creating the following applications:

  • A simple image viewer
  • A database viewer
  • A database editor
  • Calculator
  • An Archiving application (tar)
  • PDF Merging application
  • XML Editor
  • File search utility
  • Simple FTP application
  • NASA Image downloader

As you learn how to create these applications, you will also learn how wxPython works. You will go over how wxPython's event system works, how to use threads in wxPython, make use of sizers and much, much more!

"It looks to be very well done and teaches a wide range of functionality." - Robin Dunn, creator of wxPython
