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.

Inheriting from QMainWindow

Now that we have seen how to inherit from PyQt5 classes, in this recipe, we will inherit from QMainWindow. This gives us more options when it comes to designing our GUI compared to inheriting from QWidgets. In addition to setting the GUI window title, we will also give it a certain size.

Getting ready

Read through the previous recipe so that you understand the code we are writing here.

How to do it...

We will inherit from QMainWindow and specify the size of the GUI. Let's get started:

  1. Create a new module and name it GUI_PyQt5_QMainWindow...
