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.

Creating animations

Nothing quite adds a sophisticated edge to a GUI like the tasteful use of animations. Dynamic GUI elements that fade smoothly between changes in color, size, or position can add a modern touch to any interface.

Qt's animation framework allows us to create simple animations on our widgets using the QPropertyAnimation class. In this section, we'll explore how to use this class to spice up our game lobby with some animations.

Because Qt style sheets override another widget- and palette-based styling, you will need to comment out all the style sheet code for these animations to work correctly.

Basic property animations

A QPropertyAnimation object is used to animate a single Qt property of a widget...
