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.

Greetings from Qt

Now that we have looked at some of the basics of Qt Creator, let's use it to create our first program!

There is a long tradition in programming that the first program every programming class uses is Hello World! While I love traditions, I also love mixing things up a bit, so our first program will be Greetings from Qt! Obviously, our program will be an entirely different program from Hello World!

We will start by creating a project for Qt, and then we will learn about the text edit screen and how to design a simple UI. Of course, we will need to learn how to run our code. Finally, we will learn how to make sure our code stays safe as we develop and change it. The latter will become very important once we start working on our BigProject, something that will span most of this book.
