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.

In this chapter, we took a look at the core concepts of the Model-View-Delegate pattern in Qt. We explained how it is different from the traditional MVC pattern. We discussed different ways of using M/V and the convenience classes available in Qt. We learned how to apply the M/V concept in Qt Widgets as well as in Qt Quick. We discussed how to integrate a C++ Model with QML Views. We also created a few examples and implemented the concepts in our Qt application. You can now create your own Model, delegate, and Views. I hope you have understood the importance of the framework and the solid reasons for using it to meet your requirements.

In Chapter 8, Graphics and Animations, we will learn about the graphics framework and how to add animations to your Qt Quick project.
