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.

Other Qt-supported platforms

Qt 5 had support for a great range of platforms, from desktop and mobile platforms to embedded and web platforms. Qt 6 is yet to support all platforms that were supported in Qt 5, but the platforms will be gradually supported as Qt 6 matures. Currently, only embedded Linux is supported in the latest release of Qt 6 under the commercial license. You may have to wait some time to port your application to Qt 6 on a different embedded platform. Otherwise, if you want to migrate to Qt 6 immediately for your favorite embedded platform, you have to build from the source code and do the necessary modifications.

The following link provides a snapshot of embedded Linux support in Qt 6.2: This link may get updated as Qt moves to the next release.

Qt also provides a Boot to Qt software stack for embedded Linux systems under commercial licenses. It is a lightweight, Qt-optimized complete software stack that...
