What this book covers

Chapter 1, Introduction to Qt 6, will introduce you to Qt and describe how to set it up on a machine. By the end of the chapter, readers will be able to build Qt from source code and get started on their platform of choice.

Chapter 2, Introduction to Qt Creator, introduces you to the Qt Creator IDE and its user interface. This chapter will also teach you how to create and manage projects in Qt Creator. You will learn to develop a simple Hello World application using Qt Creator and learn about different shortcuts, and practical tips.

Chapter 3, GUI Design Using Qt Widgets, explores the Qt Widgets module. Here, you will learn the various kinds of widgets that are available for creating GUIs. You will also be introduced to Layouts, Qt Designer, and learn how to create your own custom controls. This chapter will help you in developing your first GUI application using Qt.

Chapter 4, Qt Quick and QML, covers fundamentals of Qt Quick and QML, Qt Quick Controls, Qt Quick Designer, Qt Quick Layouts, and Basic QML Scripting. In this chapter, you will learn to use Qt Quick controls and how to integrate C++ code with QML. By the end of this chapter, you will be able to create a modern application with fluid UI using QML.

Chapter 5, Cross-Platform Development, explores cross-platform development using Qt. You will learn about different settings in Qt Creator. In this chapter, you will be able to run sample applications on your favorite desktop and mobile platforms.

Chapter 6, Signals and Slots, covers the signals and slots mechanism in depth. You will be able to communicate between different C++ classes and between C++ and QML. You will also learn about events, event filters and event loop.

Chapter 7, Model View Programming, introduces you to the Model/View architecture in Qt and its core concepts. Here, you will be able to write custom models and delegates . You can use these to display required information on your Qt Widget-based or Qt Quick-based GUI application.

Chapter 8, Graphics and Animations, introduces the concepts of 2D graphics and animations. You will learn how to use painter APIs to draw different shapes on the screen. We will further discuss the possibility of graphics data representation using Qt's Graphics View framework and Scene Graph. This chapter will guide you towards creating an attention-grabbing user interface with animations. The chapter also touches upon the state machine framework.

Chapter 9, Testing and Debugging, explores different debugging techniques for a Qt application. You will learn about unit testing and the Qt Test framework in this chapter. We will also discuss how to use the Google Test framework with Qt Test, as well as learn about the available Qt tooling and GUI specific testing techniques.

Chapter 10, Deploying Qt Applications, discusses the importance of software deployment. You will learn to deploy a Qt application on various platforms, including desktop and mobile platforms. You will learn about the available deployment tools and steps to create an installer package.

Chapter 11, Internationalization, introduces you to internationalization. Qt provides excellent support for translating Qt Widgets and Qt Quick applications into local languages. In this chapter, you will learn how to make an application with multi-lingual support. You will also learn about inbuilt tools and various considerations for making a translation-aware application.

Chapter 12, Performance Considerations, introduces you to performance optimization techniques and how to apply them in the context of Qt programming. Here, we will discuss different profiling tools to diagnose performance problems, concentrating specifically on the tools available on Windows. In this chapter, you will learn how to profile performance with QML Profiler and benchmark your code. The chapter will also help you write high-performance optimized QML code.
