Python GUI programming with Tkinter

By: Alan D. Moore

Overview of this book

Tkinter is a lightweight, portable, and easy-to-use graphical toolkit available in the Python Standard Library, widely used to build Python GUIs due to its simplicity and availability. This book teaches you to design and build graphical user interfaces that are functional, appealing, and user-friendly using the powerful combination of Python and Tkinter. After being introduced to Tkinter, you will be guided step-by-step through the application development process. Over the course of the book, your application will evolve from a simple data-entry form to a complex data management and visualization tool while maintaining a clean and robust design. In addition to building the GUI, you'll learn how to connect to external databases and network resources, test your code to avoid errors, and maximize performance using asynchronous programming. You'll make the most of Tkinter's cross-platform availability by learning how to maintain compatibility, mimic platform-native look and feel, and build executables for deployment across popular computing platforms. By the end of this book, you will have the skills and confidence to design and build powerful high-end GUI applications to solve real-world problems.

The application has really come a long way. In this chapter, we learned about Tkinter validation, created a validation mixin class, and used it to create validated versions of the Entry, Combobox, and Spinbox widgets. We validated different kinds of data on keystrokes and focus events, and created fields that dynamically update their constraints based on the value of related fields.

In the next chapter, we're going to prepare our code base for expansion and learn how to organize a large application for easier maintenance. More specifically, we'll learn about the MVC pattern and how to structure our code in multiple files for simpler maintenance. We'll also learn more about RST and and version control software.
