Overview of this book

PyQt5 has long been the most powerful and comprehensive GUI framework available for Python, yet there is a lack of cohesive resources available for Python programmers to learn how to use it. This book will be your comprehensive guide to exploring GUI development with PyQt5. You will get started with an introduction to PyQt5, before going on to develop stunning GUIs with modern features. You will learn how to build forms using QWidgets and delve into important aspects of GUI development such as layouts, size policies, and event-driven programming. Moving ahead, you’ll discover PyQt5’s most powerful features through chapters on audio-visual programming with QtMultimedia, database-driven software with QtSQL, and web browsing with QtWebEngine. Next, in-depth coverage of multithreading and asynchronous programming will help you run tasks asynchronously and build high-concurrency processes with ease. In later chapters, you’ll gain insights into QOpenGLWidget, along with mastering techniques for creating 2D graphics with QPainter. You’ll also explore PyQt on a Raspberry Pi and interface it with remote systems using QtNetwork. Finally, you will learn how to distribute your applications using setuptools and PyInstaller. By the end of this book, you will have the skills you need to develop robust GUI applications using PyQt.

  1. You want to use QMainWindow with the calendar_app.py script from Chapter 3, Handling Events with Signals and Slots. How would you go about converting it?

The easiest approach would be the following:

    • Rename MainWindow to something like CalendarForm
    • Create a new MainWindow class based on QMainWindow
    • Create an instance of CalendarForm inside MainWindow and set it as the central widget
  1. You're working on an app and have added the sub-menu names to the menu bar but have not populated any of them with items. Your coworker says that none of the menu names are appearing on his desktop when he tests it. Your code looks correct; what is probably going on here?

Your coworker is using a platform (such as macOS) that doesn't display empty menu folders by default.
