By: Nibedit Dey

Overview of this book

Qt is a cross-platform application development framework widely used for developing applications that can run on a wide range of hardware platforms with little to no change in the underlying codebase. If you have basic knowledge of C++ and want to build desktop or mobile applications with a modern graphical user interface (GUI), Qt is the right choice for you. Cross-Platform Development with Qt 6 and Modern C++ helps you understand why Qt is one of the favorite GUI frameworks adopted by industries worldwide, covering the essentials of programming GUI apps across a multitude of platforms using the standard C++17 and Qt 6 features. Starting with the fundamentals of the Qt framework, including the features offered by Qt Creator, this practical guide will show you how to create classic user interfaces using Qt Widgets and touch-friendly user interfaces using Qt Quick. As you advance, you'll explore the Qt Creator IDE for developing applications for multiple desktops as well as for embedded and mobile platforms. You will also learn advanced concepts about signals and slots. Finally, the book takes you through debugging and testing your app with Qt Creator IDE. By the end of this book, you'll be able to build cross-platform applications with a modern GUI along with the speed and power of native apps.

Summary

This chapter explained the fundamentals of the Qt Quick module and how to create a custom UI. You learned to design and build GUIs with Qt Quick Designer and learned about Qt Quick Controls, and how to build a custom Qt Quick application. You also learned how to integrate QML with C++ and JS. You should now understand the similarities and differences between Qt Widgets and Qt Quick and be able to choose the most suitable framework for your project. In this chapter, we have learned about Qt Quick and how to create an application using QML. You also learned how to integrate QML with JS and learned about mouse and touch events.

In the next chapter, we will discuss cross-platform development using Qt Creator. You will learn to configure and build applications on Windows, Linux, Android, and macOS operating systems (OSes). We are going to learn how to port our Qt application to different platforms without too many challenges. Let's go!
