Hands-On Embedded Programming with QT

By: John Werner

Overview of this book

Qt is an open source toolkit suitable for cross-platform and embedded application development. This book uses inductive teaching to help you learn how to create applications for embedded and Internet of Things (IoT) devices with Qt 5. You’ll start by learning to develop your very first application with Qt. Next, you’ll build on the first application by understanding new concepts through hands-on projects and written text. Each project will introduce new features that will help you transform your basic first project into a connected IoT application running on embedded hardware. In addition to gaining practical experience in developing an embedded Qt project, you will also gain valuable insights into best practices for Qt development and explore advanced techniques for testing, debugging, and monitoring the performance of Qt applications. The examples and projects covered throughout the book can be run both locally and on an embedded platform. By the end of this book, you will have the skills you need to use Qt 5 to confidently develop modern embedded applications.

Important Qt Concepts

In Section 1, Getting Started with Embedded Qt, we covered the setup of our Host and Target environments, built an application and ran it on the Host, and then recompiled the application for the Target and ran it there.

Now is a good time to pause and take a look at some important Qt concepts:

  • Communicating effectively—signals and slots
  • Looking inside—the Qt introspection support
  • Differing views—model/view architecture
  • Keeping it portable—the Qt platform abstraction

When you have finished this chapter, you should have learned the following skills:

  • How to use signals and slots to talk between Qt objects (QObjects)
  • How to use introspection with Qt objects
  • How to separate the GUI presentation and application logic layers using model/view architecture
  • How to use Qt's generic methods for working with files, hardware, and so...
