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.

Responsive Application Programming - Threads

We have covered a lot of material up to this point. Way back in Chapter 4, Important Qt Concepts, we talked about threads in relation to signals and slots. In this chapter, we will take a deeper dive into Qt's multifaceted thread support.

I have broken down our discussion of Qt's thread support into three sections:

  • Examining Qt's different threading models
  • Solving problems with threads
  • Overcoming cross-thread communication and synchronization

When you have finished with this chapter, you should have learned the following subjects through hands-on examples:

  • Which threading models Qt supports and where they can be used
  • How to use threads to make a responsive UI
  • How to look at problems in terms of threads
  • How to synchronize threads
  • The different methods of sharing data between threads
  • What Qt does to support communicating...
