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 Rich Text with QTextDocument

Whether drafting business memos in a word processor, writing a blog entry, or generating reports, much of the world's computing involves the creation of text documents. Most of these applications require the ability to produce not just plain alphanumeric strings, but rich text as well. Rich text (as opposed to plain text) means text that includes styles and formatting features such as font faces, colors, lists, tables, and images.

In this chapter, we're going to learn how PyQt allows us to work with rich text by covering the following topics:

  • Creating rich text using markup
  • Manipulating rich text using QTextDocument
  • Printing rich text
