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.

Graphing with Tkinter

Tkinter is not a graphing tool. However, should you need to draw graphs with Tkinter, you can use the Canvas widget to draw graphs.

In this iteration, we will draw the following graphs:

  • Pie chart (

  • Bar graph (

  • Scatter plot (

The three graphs show up as follows:

Let's look at the pie chart first. You can easily create a pie chart in Tkinter using the Canvas widget's create_arc method.

The create_arc method has the following signature:

item_id = canvas.create_arc(x1, y1, x2, y2, option, ...)

Point (x1, y1) is the top-left corner and point (x2, y2) is the bottom-right corner of the rectangle into which the arc fits. If the bounding rectangle is a square, it makes a circle. The method also takes two arguments named start and extent that we will use to create the pie chart.

The start option specifies the start angle for the arc, measured in degrees from the +x direction. When omitted, you get the complete ellipse. The extent...
