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.

Dominating the Mobile UI

In Chapter 3, Dividing Your Project and Ruling Your Code, we created a strong core library to handle an image gallery. We will now use this gallery-core library to create a mobile application.

We will teach you how to create a Qt Quick project from scratch. You will create custom Qt Quick views with QML. This chapter will also cover how your QML views can communicate with the C++ library.

At the end of this chapter, your gallery application will run on your mobile (Android or iOS) with a dedicated GUI compliant with touch devices. This application will offer the same features as the desktop application.

This chapter covers the following topics:

  • Starting with Qt Quick and QML
  • Creating a Qt Quick project
  • Displaying albums with ListView
  • Loading a database on mobile
  • Loading images with an ImageProvider
  • Displaying thumbnails in a GridView
