Cross-Platform Development with Qt 6 and Modern C++

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.

Chapter 4: Qt Quick and QML

Qt consists of two different modules for developing a graphical user interface (GUI) application. The first approach is to use Qt Widgets and C++, which we learned about in the previous chapter. The second approach is to use Qt Quick Controls and the Qt Modeling Language (QML), which we will be covering in this chapter.

In this chapter, you will learn how to use Qt Quick Controls and the QML scripting language. You will study how to use Qt Quick Layouts and positioners and make a responsive GUI application. You will learn to integrate your backend C++ code with frontend QML. You will learn the fundamentals of Qt Quick and QML, and how to develop touch-friendly and visual-oriented Qt applications. You will also learn about mouse and touch events and how to develop a touch-aware application.

In this chapter, we're going to cover the following main topics:

  • Getting started with QML and Qt Quick
  • Understanding Qt Quick Controls
  • Creating...
