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 cross-platform development

There are several cross-platform frameworks available on the market, but Qt is a better option to select owing to its maturity and available community support. It's easy for a traditional C++ developer to adapt to Qt faster and develop high-quality applications. The Qt framework allows developers to develop applications that are compatible with multiple platforms such as Windows, Linux, macOS, QNX (originally known as Quick Unix [Qunix]), iOS, and Android. It facilitates faster application development with better code quality, with its ability to code once and its deploy-anywhere philosophy. Qt handles platform-specific implementations internally, and also enables you to build amazing ultra-lightweight applications with an impressive GUI on microcontroller-powered devices.

To develop applications using Qt for embedded platforms, you will require a commercial license to use Qt for Device Creation. Qt also supports some of the microcontroller...
