Overview of this book

Tkinter is the built-in GUI package that comes with standard Python distributions. It is a cross-platform package, which means you build once and deploy everywhere. It is simple to use and intuitive in nature, making it suitable for programmers and non-programmers alike. This book will help you master the art of GUI programming. It delivers the bigger picture of GUI programming by building real-world, productive, and fun applications such as a text editor, drum machine, game of chess, media player, drawing application, chat application, screen saver, port scanner, and many more. In every project, you will build on the skills acquired in the previous project and gain more expertise. You will learn to write multithreaded programs, network programs, database driven programs and more. You will also get to know the modern best practices involved in writing GUI apps. With its rich source of sample code, you can build upon the knowledge gained with this book and use it in your own projects in the discipline of your choice.

The class hierarchy of Tkinter


As programmers, we hardly need to understand the class hierarchy of Tkinter. After all, we have been able to code all the applications so far without bothering about the overall class hierarchy. However, knowing the class hierarchy enables us to trace the origin of a method within the source code or source documentation of a method.

In order to understand the class hierarchy of Tkinter, let's take a look at the source code of Tkinter. On Windows installation, the source code of Tkinter is located at path\of\Python\Installation\Lib\tkinter\. On my Ubuntu machine, the source code is located at /usr/lib/python3.4/tkinter/.

When you open the __init__.py file from this folder in a code editor and look at its list of class definitions in Tkinter, you will see the following structure:

So, what can you see here? We have class definitions for each core Tkinter widget. In addition to this, we have class definitions for different geometry managers and variable types defined...
