The book   Testimonials   About the author  

Buy this and you also get my PySide2 book.

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

This course helped me get a fully working demo up and running for a technical pitch. It went over extremely well!

Loved the lesson , the thing is that I don't have to memorize it. I understood it.

What's in the Book

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.

Create GUI Applications Example pages
Creating applications with Qt Designer

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.

PyQt5 themes and styles

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.

Multithreading & processes with PyQt5

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.

Plotting in PyQt5
Example PyQt5 applications

Build real apps not just examples

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

The book guides you through creating a simple Web browser, Minesweeper game, Paint 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 Qt applications for distribution on Windows, Mac and Linux.

Creating PyQt5 installers

Every chapter comes with complete, runnable code examples.

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.
