Python GUI Programming Cookbook - Third Edition

By: Burkhard Meier

Overview of this book

Python is a multi-domain, interpreted programming language that is easy to learn and implement. With its wide support for frameworks to develop GUIs, you can build interactive and beautiful GUI-based applications easily using Python. This third edition of Python GUI Programming Cookbook follows a task-based approach to help you create effective GUIs with the smallest amount of code. Every recipe in this book builds upon the last to create an entire, real-life GUI application. These recipes also help you solve problems that you might encounter while developing GUIs. This book mainly focuses on using Python’s built-in tkinter GUI framework. You'll learn how to create GUIs in Python using simple programming styles and object-oriented programming (OOP). As you add more widgets and expand your GUI, you will learn how to connect to networks, databases, and graphical libraries that greatly enhance the functionality of your GUI. You’ll also learn how to use threading to ensure that your GUI doesn't become unresponsive. Toward the end, you’ll learn about the versatile PyQt GUI framework, which comes along with its own visual editor that allows you to design GUIs using drag and drop features. By the end of the book, you’ll be an expert in designing Python GUIs and be able to develop a variety of GUI applications with ease.

Changing the entire GUI language all at once

In this recipe, we will change all of the GUI display names, all at once, by refactoring all the previously hardcoded English strings into a separate Python module and then internationalizing those strings.

This recipe shows that it is a good design principle to avoid hardcoding any strings, that our GUI displays, but to separate the GUI code from the text that is displayed by the GUI.

Designing our GUI in a modular way makes internationalizing it much easier.

Getting ready

We will continue to use the GUI from the previous recipe, GUI.py. In that recipe, we had already internationalized the title of the GUI. We will enhance the LanguageResources.py module from the previous recipe...
