Tkinter GUI Application Development Blueprints - Second Edition

By: Bhaskar Chaudhary

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, audio player, drawing application, piano tutor, chat application, screen saver, port scanner, and much 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, asyncio based programming 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.

A note on window responsiveness

We used .grid_propagate(False) in this program to ensure that our frames did not shrink to fit their contents, but rather stayed at a fixed height and width that we had specified while making the frames.

This served us well for this example, but this made our window and its content fixed in size. This is what you would typically call a non-responsive window.

Let us take a look at the program nonresponsive.py as an example of a non-responsive window. This program simply draws 10 buttons in a row:

from tkinter import Tk, Button
root = Tk()

for x in range(10):
btn = Button(root, text=x )
btn.grid(column=x, row=1, sticky='nsew')

root.mainloop()

Run this program and resize the window. These buttons are drawn on the root window and are not responsive. The buttons remain fixed in size. They do not adapt in size to change in the window size. If...
