Design Patterns in C++ with Qt

This eBook is the digital version of the printed book, teaching readers how to master C++ "The Qt Way" by focusing on design patterns and efficient reuse. The book has been updated and tested in classrooms to provide readers with a comprehensive understanding of both the C++ language and Qt libraries. Emphasizing the development of maintainable software with well-defined code layers and reusable classes and functions.

In this updated edition, every chapter has been enhanced with new content and better organization. There is also extensively revised coverage of QObjects, Reflection, Widgets, Main Windows, Models and Views, Databases, Multi-Threaded Programming, and Reflection. The book also introduces the powerful new Qt Creator IDE, multimedia APIs, and extended coverage of Qt Designer and C++ Integration. It has been restructured to help readers start writing software immediately and write robust, effective software sooner.

New design patterns, quiz questions, and labs have been added, along with efficient solutions relying on new Qt features and best practices. The book also provides an up-to-date C++ reference section and a complete application case study.

Readers will learn to master C++ keywords, literals, identifiers, declarations, types, and type conversions. They will understand how to organize classes and objects, describe their interrelationships, and learn consistent programming style and naming rules. How to work with lists, functions, and essential techniques, as well as define inheritance relationships to share code and promote reuse will be covered. The book also explains how code libraries are designed, built, and reused.

Other areas of focus include working with QObject, building graphical user interfaces with Qt widgets, using templates to write generic functions and classes, mastering advanced reflective programming techniques, and using the Model-View framework to cleanly separate data and GUI classes. Readers will also learn how to validate input using regular expressions and other techniques, parse XML data, and understand today’s most valuable creational and structural design patterns.

Additionally, the book covers how to create, use, monitor, and debug processes and threads, access databases with Qt’s SQL classes, manage memory reliably and efficiently, and effectively manage QThreads and use QtConcurrent algorithms.
