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.

Creating broader visual elements

Next, let us lay out the broader visual elements of our program. For the sake of modularity, we divide the program into four broad visual sections as shown in the following figure:

Let us define a method called init_gui() that is called from within the __init__ method as follows (see code

    def init_gui(self):

We then proceed to define all four of these methods ( The code is not discussed here as we have done similar coding in previous chapters. Further, we need five more attributes to handle the five new widgets:

        self.current_pattern = IntVar()
        self.number_of_units = IntVar()
        self.bpu = IntVar()
        self.to_loop = BooleanVar()
        self.beats_per_minute = IntVar()

We begin with the Top Bar section. The Top Bar is simple. It has a few labels, three Spinboxes, and an Entry...
