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.

Reasons for using Qt

Qt is a modular, cross-platform application development framework. The biggest misunderstanding about Qt is that many people consider it as a GUI framework. However, Qt is much more than a GUI framework. It not only comprises a GUI module, but also a set of modules to make application development faster and easier to scale on various platforms. The biggest benefit of using Qt is its ability to provide portability to various platforms. Here are some advantages of using Qt for developers:

  • You can create incredible user experiences for your customers and boost your company brand using Qt.
  • Cross-platform development saves both time and money. You can target multiple platforms with the same code base.
  • Qt is known for making C++ easy and accessible. With Qt, developers can easily create high-performance, scalable applications with a fluid UI.
  • Due to the open source model, the framework is future-proof, along with a great ecosystem.
  • It further supports different programming languages and is a very flexible and reliable framework. Consequently, there are great companies such as Adobe, Microsoft, Samsung, AMD, HP, Philips, and MathWorks using Qt for their applications. Many open source projects such as VLC (previously known as VideoLAN Client), Open Broadcaster Software (OBS), and WPS Office (where WPS stands for Writer, Presentation, and Spreadsheets) are also built on Qt.

The core values of Qt are outlined as follows:

  • Cross-platform nature
  • Highly scalable
  • Very easy to use
  • Built-in with world-class application programming interfaces (APIs), tools, and documentation
  • Maintainable, stable, and compatible
  • A large community of users

Whether you are a hobbyist, a student, or working for a company, Qt provides great flexibility to use its modules as per your requirement. Many universities are using Qt as one of their coursework subjects. So, Qt is a great choice for programmers to start building new applications with ready-made features. Let's start by downloading and installing Qt 6 on your machine.
