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.

Setting up the GUI in OOP

The text editor we developed in the previous chapter was implemented in procedural code. Although it offered some benefits for quick coding, it had some typical limitations:

  • We started encountering global variables

  • The function definitions needed to

  • be defined above the code that called them

  • Most importantly the code

  • was not reusable.

Therefore, we need some way to ensure that our code is more reusable. This is why programmers prefer to use Object Oriented Programming (OOP) to organize their code into classes.

OOP is a programming paradigm that shifts the focus onto the objects we want to manipulate rather than the logic required to manipulate them.

This is in contrast to procedural programming that views a program as a logical procedure that takes input, processes it, and produces some output.

OOP provides several benefits such as data abstraction, encapsulation, inheritance, and polymorphism. In addition, OOP provides a clear modular structure for programs. Code modification...
