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.

Packaging for OS X

On OS X, applications are built and run from a bundle: a single directory that contains the application binary and all its dependencies. In the finder, these bundles are viewed as .app special directories.

When running gallery-desktop from Qt Creator, the application is already bundled in a .app file. Because we are using a custom library, called gallery-core, this does not contain all the dependencies, and Qt Creator handles it for us.

What we aim to create is a script that completely packages gallery-desktop (gallery-core included) in a .dmg file, an OS X disk image file that is mounted upon executionn and lets the user install the application with ease.

To achieve this, Qt provides the macdeployqt tool, which gathers the dependencies and creates the .dmg file.

First, check that your environment variables are correctly set, as shown in...
