This book is for application developers who want a powerful and flexible framework to create modern, responsive applications on Microsoft Windows, Apple Mac OS X, and Linux desktop platforms. You should be comfortable with C++ but no prior knowledge of Qt or QML is required.

If you are a programmer looking for a truly cross-platform GUI framework to help you save your time by side-stepping the incompatibility between different platforms and building applications using Qt 5 for multiple targets, then this book is most certainly intended for you. It is assumed that you have a basic programming experience of C++ and fundamental knowledge about Qt.

Qt是一个跨平台C++图形用户界面应用程序开发框架，既可以开发GUI程序，也可以开发非GUI程序，比如控制台工具和服务器等，在软件工业界有广泛的应用。本书分为15章，内容包括Qt概述、开发环境、编程基础、对话框程序设计、控件设计、数据库编程、调用Windows动态链接库、使用Linux静态库和共享库、文件编程、菜单栏/工具栏和状态栏、图形编程、多线程编程、多媒体编程、网络编程、应用程序发布。本书既适合Qt编程初学者、Qt跨平台应用开发人员阅读，也适合作为高等院校和培训学校相关专业的教材。

Qt是十分著名的跨平台C++可视化开发平台，Qt开源版提供了与商业版同样的功能，《Qt 5开发及实例》（第2版）在继承广受市场欢迎的《Qt 5开发及实例》（第1版）特点的同时，以Qt 5.4.0为平台，介绍QT应用开发更系统，可读性更强。本书主要分为两大部分：第一部分是传统的Qt Widget编程，每章在简单介绍开发环境的基础上，用一个小实例，介绍Qt 5应用程序开发的各方面，然后系统介绍Qt 5应用程序的开发技术，一般均通过实例介绍和讲解内容。最后通过三个大实例，系统介绍Qt 5综合应用开发。第二部分是新增的QML及Qt Quick开发，包括QML编程基础、动画特效及Qt Quick的控件窗体程序设计，这部分同样以实例讲解知识点，并且在最后给出一个大综合实例。本书末章仍保留有老版Linux下Qt安装和使用的内容以方便读者。光盘中包含本书教学课件和书中所有实例的源代码及其相关文件。 通过学习本书，结合实例上机练习，一般能够在比较短的时间内系统地了解和掌握Qt 5各方面的应用技术。

PyQt is one of the best cross-platform interface toolkits currently available; it's stable, mature, and completely native. If you want control over all aspects of UI elements, PyQt is what you need. This book will guide you through every concept necessary to create fully functional GUI applications using PyQt, with only a few lines of code.As you expand your GUI using more widgets, you will cover networks, databases, and graphical libraries that greatly enhance its functionality. Next, the book guides you in using Qt Designer to design user interfaces and implementing and testing dialogs, events, the clipboard, and drag and drop functionality to customize your GUI. You will learn a variety of topics, such as look and feel customization, GUI animation, graphics rendering, implementing Google Maps, and more. Lastly, the book takes you through how Qt5 can help you to create cross-platform apps that are compatible with Android and iOS. You will be able to develop functional and appealing software using PyQt through interesting and fun recipes that will expand your knowledge of GUIs.

If you want to create great graphical user interfaces and astonishing games with Qt, this book is ideal for you. No previous knowledge of Qt is required; however knowledge of C++ is mandatory.

With the growing need to develop GUIs for multiple targets and multiple screens, improving the visual quality of your application becomes important so that it stands out from your competitors. With its cross-platform ability and the latest UI paradigms, Qt makes it possible to build intuitive, interactive, and user-friendly user interfaces for your applications.Qt5 C++ GUI Programming Cookbook, Second Edition teaches you how to develop functional and appealing user interfaces using the latest version of QT5 and C++. This book will help you learn a variety of topics such as GUI customization and animation, graphics rendering, implementing Google Maps, and more. You will also be taken through advanced concepts like asynchronous programming, event handling using signals and slots, network programming, various aspects of optimizing your application. By the end of the book, you will be confident to design and customize GUI applications that meet your clients' expectations and have an understanding of best practice solutions for common problems.

Achieving efficient code through performance tuning is one of the key challenges faced by many programmers. This book looks at Qt programming from a performance perspective. You'll explore the performance problems encountered when using the Qt framework and means and ways to resolve them and optimize performance.The book highlights performance improvements and new features released in Qt 5.9, Qt 5.11, and 5.12 (LTE). You'll master general computer performance best practices and tools, which can help you identify the reasons behind low performance, and the most common performance pitfalls experienced when using the Qt framework. In the following chapters, you’ll explore multithreading and asynchronous programming with C++ and Qt and learn the importance and efficient use of data structures. You'll also get the opportunity to work through techniques such as memory management and design guidelines, which are essential to improve application performance. Comprehensive sections that cover all these concepts will prepare you for gaining hands-on experience of some of Qt's most exciting application fields - the mobile and embedded development domains.By the end of this book, you'll be ready to build Qt applications that are more efficient, concurrent, and performance-oriented in nature.

Qt 5.9 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This learning path demonstrates the power and flexibility of the Qt framework for desktop application development and shows how you can write an application once and deploy it to multiple operating systems. It will address all the challenges while developing cross-platform applications with the Qt framework.This course will give you a better understanding of the Qt framework and tools to resolve serious issues such as linking, debugging, and multithreading. It will also upskill you by explaining how to create a to-do-style app and taking you through all the stages in building a successful project. You will build a suite of apps; while developing these apps, you’ll deepen your knowledge of Qt Quick's layout systems, and see Qt 3D and widgets in action. The next project will be in the industrial and agricultural sectors: making sense of sensor data via a monitoring system. Your apps should run seamlessly across devices and operating systems such as Android, iOS, Windows, or Mac, and be cost-effective by integrating with existing web technologies. You take the role of lead developer and prototype a monitoring system. In doing so, you’ll get to know Qt's Bluetooth and HTTP APIs, as well as the Charts and Web Engine UI modules. These projects will help you gain a holistic view of the Qt framework.
