Inside the book

Basic concepts and first steps

Starting from the very basics of creating a desktop window this modern PyQt6 book takes you on a tour of the key features of PyQt6. We'll look at the basic building blocks of PyQt6 applications — Widgets, Layouts & Signals and learn how PyQt6 uses the event loop to handle and respond to user input.

Designing UIs with Qt Designer

Build your user interfaces visually in the Qt Designer drag-and-drop editor. We'll take a quick tour of the designer and show how to load your created interface into Python.

Unleash your creativity

Think the default look of Qt is a bit drab? You can customize almost anything using Styles, Palettes and Qt Style Sheets. We'll take a tour through how you can use these to completely customize the look and feel of your applications.

Build data-driven applications

Use PyQt6's MVC-like interface to work efficiently with data, right in your applications. Use custom data stores and sync widgets automatically, allowing you to focus on the logic.

Use tabular views to display SQL databases and numpy or pandas datastructures. Use linked widgets for easy editing.

Create your own custom widgets

PyQt6 provides a huge number of built-in widgets, but sometimes you need a little something extra. Starting with an introduction to bitmap graphics we'll build up to creating entirely custom-drawn widgets for your apps.

Efficient apps with threads and processes

Are your apps stuttering to a halt? Learn how to use threads & processes to keep long-running calculations, loading large files or connections to remote servers all running smoothly.

Capture output from threads and processes and keep your users informed with progress bars and thread managers.

Visualize data with interactive charts

Use matplotlib or PyQtGraph to display data within your app. Use threads to create live dashboards, pulling data from your calculations or remote services.

Unlock the data-analysis capabilities of Python from within your applications.

Build real apps not just examples

Move beyond simple examples, learning how to use to create fully-functional applications.

The book guides you through creating a simple Web browserMinesweeper gamePaint app and a Simple Todo reminder, using the features you've learned.

Package your apps for distribution

Once your app is ready, it's time to share it!

Discover how to package your applications for distribution on Windows, Mac and Linux.
