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.

We began the chapter by discussing the application deployment problem and learning the difference between static and dynamic libraries. Then we discussed the different deployment tools in Qt and the specific case of Windows deployment and installation. Armed with this knowledge, we deployed a sample app on Windows and created an installer using the Qt Installer Framework. In addition, we discovered deploying applications on Linux and macOS and honed our skills for deploying applications on various platforms. Later, we explained some of the important points to be considered before publishing a Qt-based Android application to the play store.

Finally, we looked at some third-party installer utilities. To summarize, you have learned to develop, test, and deploy a Qt application on various platforms. With this knowledge, you should be able to create your installation packages and share them with the world.

In Chapter 11, Internationalization, we will learn about developing...
