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.

Getting started with QML and Qt Quick

QML is a UI markup language. It is a declarative language that is part of the Qt framework. It enables the building of fluid and touch-friendly UIs and came into existence with the evolution of touchscreen mobile devices. It was created to be highly dynamic, where developers can easily create fluid UIs with minimal coding. The Qt QML module implements the QML architecture and provides a framework for developing applications. It defines and implements the language and infrastructure, and provides application programming interfaces (APIs) to integrate the QML language with JS and C++.

Qt Quick provides a library of types and functionality for QML. It comprises interactive types, visual types, animations, models, views, and graphics effects. It is used for mobile applications where touch input, fluid animations, and user experience are crucial. The Qt QML module provides the language and infrastructure for QML applications, whereas the Qt Quick...
