Qt 6.9 Professional Programming with C++: Cross-Platform GUI Development with Qt Widgets, Qt Quick, QML, Mobile Apps, and AI-Assisted Workflows - From Beginner to Professional

The framework changed. Your reference book didn't — until now.

Qt 6 has been out for years, AI has rewritten how developers write code, and most Qt books on the market still teach Qt 5 patterns with zero mention of AI-assisted workflows. If you're building cross-platform C++ applications in 2026, you're stitching together outdated books, scattered forum threads, and hopeful ChatGPT prompts.

There's a better way — and over a million Qt developers already know it.

For more than 20 years, this book — now in its 7th edition — has been one of the most trusted Qt references in the world, continuously rewritten as Qt itself evolved. This English edition is fully rebuilt for Qt 6.9 : over 1,900 pages, 200+ fully compilable example programs, and — for the first time — an entire section on using AI tools (ChatGPT, Claude, Cursor, Ollama, LM Studio) inside your real Qt development workflow.

Whether you're writing your first widget or leading a migration off Qt 5, this book meets you where you are:

New to Qt? Step-by-step foundations with compact, runnable examples — no prior Qt experience assumed. Building real applications? Deep coverage of complex GUI components, Graphics View, OpenGL, multimedia, Qt WebEngine, and database/network programming. Going cross-platform or mobile? Full sections on Qt Quick, QML, 3D graphics, and shipping mobile apps to the iOS App store. Leading a team or migrating a codebase? Dedicated Qt 5 → Qt 6 migration guidance, performance optimization, and architecture patterns. Curious what AI actually changes about Qt development? 16 battle-tested prompts for architecture planning, UI design, code generation, testing, and debugging — compatible with local and cloud models. What developers have said about earlier editions:

A great book — the content is outstanding. — Stepan P.
The best book on Qt. I especially appreciate the author's thorough, detailed responses. — D.
A true treasure trove of information with an impressive breadth of topics. — Eldar M.
An excellent introduction and an invaluable ongoing reference. — Sergey

Inside, across 10 parts and 70 chapters: Qt fundamentals and the object model · Controls, layouts, and events · 2D/3D graphics, OpenGL, and multimedia · Application architecture (settings, i18n, menus, dialogs) · Files, networking, databases, XML/JSON, plugins, and testing · JavaScript scripting in Qt · Qt Quick and QML (animation, model/view, Qt 3D) · Mobile app development and publishing · Qt and AI — chatbots, AI-assisted IDEs, and prompt engineering.

Every chapter ends with comprehension checkpoints, hands-on exercises, and access to a companion online platform to discuss the material with other readers.

This isn't a book you read once. It's the reference you keep open in a second monitor for years.
