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.
