Qt 6.9 Professional Programming with C+‪+‬

Cross-platform software development is no longer the future — it's the present. This is your complete, all-in-one training system for that era: from your very first lines of Qt code to modern, AI-powered developer workflows.

For over 20 years, this book has been one of the most trusted and widely used Qt resources in the Russian-speaking developer community — continuously refined across seven editions. This is its first English edition: fully rewritten and modernized for Qt 6.9.

Inside this 1,100+ page course and reference, you'll find:

+ 200+ fully functional example programs — ready to compile, run, and reuse in your own projects
+ Battle-tested AI prompts for architecture planning, UI design, code generation, test automation, and debugging, compatible with both local and cloud-based models
+ Interactive learning checkpoints at the end of every chapter — comprehension questions, hands-on exercises, and access to a companion online platform
+ Ten systematically structured parts covering Qt fundamentals, controls, events, 2D/3D graphics and multimedia, application architecture, networking and databases, JavaScript, Qt Quick and QML, mobile app development, and a dedicated section on Qt and AI

Whether you're writing your first Qt program, building complex GUI applications with WebEngine and multimedia, leading a team through a Qt 5-to-Qt 6 migration, or teaching Qt in a university course, this book meets you where you are and grows with you.
