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 5: Cross-Platform Development

Qt has been well known for its cross-platform capability since its initial release—it was the primary vision behind creating this framework. You can use Qt Creator on your favorite desktop platforms such as Windows, Linux, and macOS, and create fluid, modern, touch-friendly graphical user interfaces (GUIs) and desktop, mobile, or embedded applications with the same code base or with a little modification. You can easily modify your code and deploy it on a target platform. Qt has several built-in tools to analyze your application and its performance on various supported platforms. Furthermore, it's easy to use and has an intuitive user interface (UI), unlike with other cross-platform frameworks.

In this chapter, you will learn cross-platform development essentials and how to build applications on different platforms. With this, you will be able to run sample applications on your favorite desktop and mobile platforms.
