Application Development with Qt Creator - Third Edition

By: Lee Zhi Eng, Ray Rischpater

Overview of this book

Qt is a powerful development framework that serves as a complete toolset for building cross-platform applications, helping you reduce development time and improve productivity. Completely revised and updated to cover C++17 and the latest developments in Qt 5.12, this comprehensive guide is the third edition of Application Development with Qt Creator. You'll start by designing a user interface using Qt Designer and learn how to instantiate custom messages, forms, and dialogues. You'll then understand Qt's support for multithreading, a key tool for making applications responsive, and the use of Qt's Model-View-Controller (MVC) to display data and content. As you advance, you'll learn to draw images on screen using Graphics View Framework and create custom widgets that interoperate with Qt Widgets. This Qt programming book takes you through Qt Creator's latest features, such as Qt Quick Controls 2, enhanced CMake support, a new graphical editor for SCXML, and a model editor. You'll even work with multimedia and sensors using Qt Quick, and finally develop applications for mobile, IoT, and embedded devices using Qt Creator. By the end of this Qt book, you'll be able to create your own cross-platform applications from scratch using Qt Creator and the C++ programming language.

Deploying applications to Android devices

In this section, we will learn how we can build and deploy our Qt application specifically for Android devices. Deploying to Android devices is quite different from desktop or iOS. There are some setups that we need to do before we're able to deploy the app to an Android device:

  1. Let's open up the Build Settings interface by clicking on the wrench icon that says Projects located on the left panel. Please make sure that you have selected one of the Android kits (for example, Android for arm64-v8a) before doing so:
  1. After that, you will see some additional settings available on the Build Settings interface, called Build Android APK, which is specifically for the Android platform only. You will not see these settings on other build platforms:

Let's take a look at the settings one by one:
