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.

Who are you?

Now that we have created a project, designed a simple UI, built and run the application, and committed our code to a local repository, let's add to the project. As noted before, there really isn't much to make our little application interesting. Why don't we add something to it?

We will start by adding a place for the user to enter their name and then use the name to directly address them in the text.

Adding a place to type your name

For our next trick, let's see whether we can get the application to address us by name. We should have a line editing widget with a label saying My name is:.

Before you look further down, why don't you try adding the elements to the design yourself?

The following...
