What you'll learn

Basic concepts and first steps

Starting from the very basics of creating a desktop window the book takes you on a tour of the key features of PySide2 you can use to build real-life applications.

We'll look at the basic building blocks of Qt applications — Widgets, Layouts & Signals and learn how Qt 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 Qt'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

Qt 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.

Package your apps for distribution

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

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

Every chapter comes with hundreds of complete, runnable code examples.

What people are saying

Good start, looking forward to updates covering more advanced topics such as interacting with databases and APIs.

Thanks for this great book! You explain things so clearly.

As a beginner and hobbyist programmer trying to learn Python and implement a GUI this book a must-have.

Learn to make real apps

Build fully-functional PySide2 applications instead of just toy examples. These apps introduce complex features including working with events, custom signals and multithreading. Full source code for all apps included, free to copy and use in your own applications.

About me

Martin Fitzpatrick PhD

Senior Software Engineer, developing PyQt apps for 8 years.

I have been developing PyQt5 apps for 8 years. Building desktop applications to make data-analysis tools more user-friendly, Python was the obvious choice. Starting with Tk, later moving to wxWidgets and finally adopting PyQt, I haven't looked back since.

I love the flexibility Python gives you to create fun and useful things quickly. Paired with Qt it's a great way to build professional apps on the desktop.
