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.

Understanding the need for deployment

The process of making software work on a target device, whether it's a test server, a production environment, a user's desktop, or mobile device, is known as software deployment. Typically, end users want a single file that they can open to access your application. The user will not want to go through several processes to obtain various alien files. Usually, users look for software that they can launch with a double click or tap. The user will not want to go through a series of steps to obtain a number of unknown files. In this chapter, we will discuss the steps and things to consider while deploying a Qt application. We will discuss deploying the application on Windows, Mac, Linux, and Android platforms.

We've just been running debug versions of the applications we've built so far. You should make release binaries for generating deployment packages. The difference between these two alternatives is that the debug version...
