Modern Tkinter for Busy Python Developers: Quickly learn to create great looking user interfaces for Windows, Mac and Linux

Fourth Edition: thoroughly revised and expanded! Updated for Python 3.14. Now includes Tkinter API reference, and bonus material on structuring and refining Tkinter code and third-party themes and widgets.

Quickly learn the right way to build attractive and modern graphical user interfaces with Python and Tkinter, its standard GUI toolkit.

Tkinter has been around forever. There's a lot of documentation, much of it created years ago. But it's all wrong. Tkinter took a quantum leap forward since that documentation was written. Your program needs to be written differently to take advantage of that. Modern Tkinter shows you the right way to do it.

Whether you're entirely new to Tkinter, or just need to bring your Tkinter knowledge up to date, this book gives you all you need to build modern, attractive Tkinter user interfaces that run on Windows, macOS, and Linux.

You'll learn all the modern best practices. You'll build your user interface the right way the first time, without having to learn anything extra or irrelevant. It starts at the beginning, shows you what you need to know, and covers all the essential elements of building your modern user interface. This includes:

all the standard GUI widgets
attractively laying out your user interface
managing menus, windows, and dialogs
organizing more complex user interfaces
Tkinter's powerhouse widgets: canvas and text
customizing the look of your user interface
making it all work on macOS, Windows, and Linux
You may have been using older documentation or are updating a Tkinter program written years ago. If so, you'll find warnings of what to avoid using, and how to replace it with a modern solution. There's even a full case study of modernizing the user interface of a seriously out-of-date Tkinter application you may be familiar with.

Let veteran software developer Mark Roseman show you the right way to build user interfaces with Python and Tkinter. He's been using Tk (the technology behind Tkinter) since its early days. He's shipped dozens of open source tools and commercial applications based on it.

He's also the author of the multi-lingual TkDocs.com website, the de facto online guide for building modern Tk user interfaces. This book brings together all new material and Python-specific information from that site and supports its further evolution.
