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.

Third-Party Libraries without a Headache

In previous chapters, we used our own libraries or the ones provided by Qt. In this chapter, we will learn how to integrate the third-party library OpenCV with a Qt project. This library will give you an impressive image processing toolbox. For each platform, you will learn to use a specific compiler link configuration.

Qt Designer is a powerful WYSIWYG editor. This is why this chapter will also teach you to build a Qt Designer plugin that can be dragged and dropped from the Widget Box to the Form Editor, and then configured directly from Qt Creator.

In the example project, the user can load a picture, select a filter from thumbnail previews, and save the result. This application will rely on OpenCV's functions for image processing.

This chapter will cover the following topics:

  • Creating your Qt Designer plugin
  • Implementing your OpenCV...
