"《An Introduction to Design Patterns in C++ with Qt 2nd Edition》是2012年出版的一本书,旨在介绍如何在C++编程中结合Qt框架应用设计模式。该书作为Prentice Hall Open Source Software Development Series的一部分,旨在提供开源技术的最佳实践,帮助读者不仅了解如何在项目中使用这些技术,而且能从实际代码中学习开源开发者的经验。书中涵盖的内容广泛,适用于多种系统,包括专有系统、Linux系统、传统UNIX系统和大型机。" 这本书深入探讨了C++与Qt结合时的设计模式概念,这对于软件开发人员来说是一份宝贵的资源。设计模式是一种在特定情境下解决问题的标准化解决方案,它们是经过验证的、可重用的、面向对象的设计实践,可以帮助开发者构建更高效、可维护的代码。在C++这样的强类型语言中,设计模式尤其重要,因为它们可以提升代码的灵活性、可扩展性和可测试性。 Qt是一个流行的跨平台应用程序开发框架,由Qt Company开发,支持Windows、macOS、Linux、Android和iOS等多个操作系统。通过Qt,开发者可以用C++编写一次代码,然后在多个平台上运行,大大简化了跨平台应用的开发工作。书中2nd Edition可能包含Qt的更新版本和新特性,以及对设计模式在Qt环境中的最新应用。 书中可能涵盖了以下设计模式: 1. 工厂模式:用于创建对象,提供一个接口来创建对象,但让子类决定实例化哪个类。 2. 单例模式:确保一个类只有一个实例,并提供一个全局访问点。 3. 观察者模式:定义对象间的一对多依赖关系,当一个对象的状态发生改变时,所有依赖于它的对象都会得到通知并自动更新。 4. 代理模式:为其他对象提供一种代理以控制对这个对象的访问。 5. 模板方法模式:定义一个操作中的算法骨架,而将一些步骤延迟到子类中,使得子类可以不改变一个算法的结构即可重定义该算法的某些特定步骤。 6. 装饰模式:动态地给一个对象添加一些额外的职责,可以增加功能而不影响其他对象。 除此之外,作者Alan Ezust和Paul Ezust可能还会讨论如何在实际项目中集成这些设计模式,如何优化Qt应用的性能,以及如何利用Qt的信号和槽机制来实现响应式编程。这本书对于想要提高C++和Qt开发技能的程序员来说,是一本不可多得的参考资料。

Master C++ "The Qt Way" with Modern Design Patterns and Efficient Reuse This fully updated, classroom-tested book teaches C++ "The Qt Way," emphasizing design patterns and efficient reuse. Readers will master both the C++ language and Qt libraries, as they learn to develop maintainable software with well-defined code layers and simple, reusable classes and functions. Every chapter of this edition has been improved with new content, better organization, or both. Readers will find extensively revised coverage of QObjects, Reflection, Widgets, Main Windows, Models and Views, Databases, Multi-Threaded Programming, and Reflection. This edition introduces the powerful new Qt Creator IDE; presents new multimedia APIs; and offers 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. The authors introduce several new design patterns, add many quiz questions and labs, and present more efficient solutions relying on new Qt features and best practices. They also provide an up-to-date C++ reference section and a complete application case study. * Master C++ keywords, literals, identifiers, declarations, types, and type conversions. * Understand classes and objects, organize them, and describe their interrelationships. * Learn consistent programming style and naming rules. * Use lists, functions, and other essential techniques. * Define inheritance relationships to share code and promote reuse. * Learn how code libraries are designed, built, and reused. * Work with QObject, the base class underlying much of Qt. * Build graphical user interfaces with Qt widgets. * Use templates to write generic functions and classes. * Master advanced reflective programming techniques. * Use the Model-View framework to cleanly separate data and GUI classes. * Validate input using regular expressions and other techniques. * Parse XML data with SAX, DOM, and QXmlStreamReader. * Master today's most valuable creational and structural design patterns. * Create, use, monitor, and debug processes and threads. * Access databases with Qt's SQL classes. * Manage memory reliably and efficiently. * Understand how to effectively manage QThreads and use QtConcurrent algorithms.
