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.

Deploying translations

In previous sections, we learned how to create translation-aware applications using both Qt Widgets and QML. You don't have to ship the .ts files with your application. To deploy translations, your release team must use the updated .qm files and ship them with the application package. The .qm files required for the application should be placed in a location where QTranslator can locate them. Typically, this is done by embedding qm files in a resource (.qrc) file or specifying a path that contain the .qm files relative to QCoreApplication::applicationDirPath(). The rcc tool is used to embed the translation files into a Qt application during the build process. It works by producing a corresponding C++ file containing specified data.

You can automate the generation of .qm files by adding a script to your .pro file. You do it by following these steps:

  1. To begin, use the language codes to declare the languages under the LANGUAGES variable in your Qt...
