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.

Configuring the project for Mac

The first step in making the project work on Mac OS is to install OpenCV. Fortunately, this is very easy using the brew command. If you develop on Mac OS and do not use it already, you should download it right now. In a nutshell, brew is an alternative package manager that gives you access to many packages (for developers and non-developers) that are not available in the Mac App Store.

You can download and install brew from

In a Terminal, simply type the following command:

 brew install opencv

This will download, compile, and install OpenCV on your machine. At the time of writing, the latest OpenCV version available on brew was version 3.2. Once this is done, open and add the following block:

macx { 
    target.path = "$$(QTDIR)/../../"
