▶Book Description
Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects.

Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt.

By the end of this book, you'll have created an application that has been tested and is ready to be shipped

▶What You Will Learn
？ Create stunning UIs with Qt Widgets and Qt Quick 2
？ Develop powerful, cross-platform applications with the Qt framework
？ Design GUIs with the Qt Designer and build a library in it for UI previews
？ Handle user interaction with the Qt signal or slot mechanism in C++
？ Prepare a cross-platform project to host a third-party library
？ Use the Qt Animation framework to display stunning effects
？ Deploy mobile apps with Qt and embedded platforms
？ Interact with a gamepad using Qt Gamepad

▶Key Features
？ Unleash the power of Qt 5.11 with C++
？ Build applications using Qt Widgets (C++) or Qt Quick (QML)
？ Create cross-platform applications for mobile and desktop platforms with Qt 5

▶Who This Book Is For
This book will appeal to developers and programmers who would like to build GUI-based applications. You should be fluent in C++ and the object-oriented paradigm. Qt knowledge is recommended but is not necessary.

▶What this book covers
？ Chapter 1, Get Your Qt Feet Wet, lays the fundamentals of Qt and refreshes your memory with a todo application. This chapter covers the Qt project structure, how to use the designer, basic principles of the signals and slots mechanism, and introduces new features of C++14.

？ Chapter 2, Discovering QMake Secrets, takes a deep dive in the heart of the Qt compilation system: qmake. This chapter will help you understand how it works, how to use it, and how you can structure a Qt application with platform-specific code by designing a system monitoring application.

？ Chapter 3, Dividing Your Project and Ruling Your Code, analyzes the Qt model/view architecture and how a project can be organized by developing a custom library with the core logic of the application. The project example is a persistent gallery application.

？ Chapter 4, Conquering the Desktop UI, studies the UI perspective of the model/view architecture with a Qt Widget application relying on the library completed in the previous chapter.

？ Chapter 5, Dominating the Mobile UI, adds the missing part of the gallery application with the mobile version (Android and iOS); the chapter covers it with the use of QML, Qt Quick controls, and QML / C++ interactions.

？ Chapter 6, Even Qt Deserves a Slice of Raspberry Pi, continues to the road on Qt Quick application with the Qt 3D perspective. This chapter covers how to build a 3D snake game targeted at the Raspberry Pi.

？ Chapter 7, Third-Party Libraries Without a Headache, covers how a third-party library can be integrated in a Qt project. OpenCV will be integrated with an image filter application that also provides a custom QDesigner plugin.

？ Chapter 8, Animations, It's Alive, Alive!, extends the image filter application by adding animations and the ability to distribute a custom SDK to let other developers add their own filters.

？ Chapter 9, Keeping Your Sanity with Multithreading, investigates the multithreading facilities provided by Qt by building a multithreaded Mandelbrot fractal drawing application.

？ Chapter 10, Need IPC? Get Your Minions to Work, broadens the Mandelbrot fractal application by moving the calculation to other processes and managing the communication using sockets.

？ Chapter 11, Having Fun with Serialization, covers multiple serialization formats (JSON, XML, and binary) inside a drum machine application in which you can record and load sound loops.

？ Chapter 12, You Shall (Not) Pass with QTest, adds tests to the drum machine application and studies how the Qt Test frameworks can be used to make unit tests, benchmarking, and GUI events simulation.

？ Chapter 13, All Packed and Ready to Deploy, gives insights into how to package an application on all desktop OSes (Windows, Linux, and Mac) and mobile platforms (Android and iOS).

？ Chapter 14, Qt Hat Tips and Tricks, gathers some tips and tricks to develop with Qt with pleasure. It shows how to manage sessions in Qt Creator, useful Qt Creator keyboard shortcuts, how you can customize the logging, save it to disk, and much more.

출판사 서평

▶ Preface
C++ is a powerful language. Coupled with Qt, you have in your hands a crossplatform framework that allies performance and ease of use. Qt is a vast framework that provides tools in many areas (GUI, threads, networking, and so on). 25 years after its inception, Qt continues to evolve and grow with each release.

This book aims to teach you how to squeeze the best out of Qt 5.11 with the new C++14 additions (lambdas, smart pointers, enum classes, and so on). These two technologies together bring you a safe and powerful development toolbox. Throughout the book, we try to emphasize a clean architecture that lets you create and maintain your application in a complex environment.

Each chapter is based on an example project that is the basis of all the discussion. Here are some tasters about what we will see in this book:

？ Uncover qmake secrets
？ Take a deep dive in the model/view architecture and study how you can build a complex application with this pattern
？ Study QML and Qt Quick applications in mobile
？ Develop Qt 3D components using QML and JavaScript
？ Show how to develop plugins and SDKs using Qt
？ Cover the multi-threading technologies provided by Qt
？ Build an IPC mechanism using sockets
？ Serialize data using XML, JSON, and binary format
？ Interact with a gamepad using Qt Gamepad

We'll cover all this and much, much more.

Note that you can take a look at Chapter 14, Qt Hat Tips and Tricks, whenever you want if you want to get some development candies and see some code snippets that might make your development more pleasurable.

And most importantly, have fun writing Qt applications!
