Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

Summary

In this chapter, you learned how to integrate a third-party library with each desktop OS (Windows, Linux, and Mac OS). We chose the OpenCV library, which has been included in a custom Qt Designer plugin and which can display a live preview of your image processing result in Qt Designer. We created an image-filtering application that can open pictures, apply filters to them, and save the result on your machine.

We had a good look at how you can integrate third-party libraries and how you can make a Qt Designer plugin. In the next chapter, we will push things forward by making the image-filter application ready to load filter plugins that could be implemented by third-party developers. To make things even cooler, we will cover the Qt animation framework to make the image-filter more spectacular.
