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.

Two roads diverge

In his 1916 poem, The Road Not Taken, Robert Frost ponders having to decide which way to go at a fork on a wooded trail. In a sense, Qt offers the same dilemma.

For the most part of two decades, Qt had only one technology for GUI development—Qt Widgets. Qt Widgets are built and coded in C++. If you wish to create a custom version of a widget, you are forced to use C++. In 2011, a new method of developing UIs was introduced with the goal of making GUI development, especially on mobile devices, easier and quicker. Instead of coding in C++, a JavaScript-like language (QML) was used and a graphics framework, Qt Quick, was developed.

In this section, we will look at how to create both widget and QML-based GUIs and look at an overview of how they are coded.

Let's start exploring the two technologies by looking at Qt Widgets.
