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.

Building a screen saver

We will start by building a screen saver. The program will consist of several random-colored and random-sized balls bouncing all over the screen at random velocity, as shown in the following screenshot:

Let's create a class to generate balls with random attributes. Accordingly, we define a new class named RandomBall.

class RandomBall:

    def __init__(self, canvas):
        self.canvas = canvas
        self.screen_width = canvas.winfo_screenwidth()
        self.screen_height = canvas.winfo_screenheight()
    def create_ball(self):

    def generate_random_attributes(self):
        self.radius = r = randint(40, 70)
        self.x_coordinate = randint(r, self.screen_width - r)
        self.y_coordinate = randint(r, self.screen_height - r)
        self.x_velocity = randint(6, 12)
        self.y_velocity = randint(6, 12)
        self.color ...
