✦ Synopsis

Building desktop applications doesn't have to be difficult. Using Python & Qt6 you can create fully functional desktop apps in minutes. Starting from the very basics, this modern PyQt6 book takes you on a tour of the key features of PyQt6 you can use to build real-life applications.

This is the 2nd Edition of Create GUI Applications with Python & Qt6, updated for 2022 & PyQt6. Learn the fundamental building blocks of PyQt applications — Widgets, Layouts & Signals and learn how PyQt6 uses the event loop to handle and respond to user input. Design beautiful UIs with Qt Designer and customize the look and feel of your applications with Qt Style Sheets and custom widgets.Use Qt's MVC-like ModelViews framework to connect data sources to your widgets, including SQL databases, numpy and pandas data tables, to build-data driven application. Visualize data using matplotlib & PyQtGraph and connect with external data sources to build live dashboards. Learn how to use threads and processes to manage long-running tasks and communicate with external services. Parse data and visualize the output in logs and progress bars.The book includes usability and architectural tips to help you build maintainable and usable PyQt6 applications from the start. Finally, once your application is ready to be released, discover how to package it up into professional-quality installers, ready to ship.
