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.

Differing views — model/view architecture

A consistent theme between Qt Widgets and QML, the two GUI technologies Qt offers, is the use of the model/view architecture.

Simply put, the model/view architecture separates the data (model) from the display (view) of the data. This allows you to separate how the data is updated from how the UI designer presents the data. Should the UI designer change how the data is viewed, the code that puts the data in the model doesn't have to be changed.

A quick dive

For whatever reason, the concept of a model/view architecture was one of the harder ones for me to understand. It is really straightforward, but I had a mental block. Finally, I wrote some sample code to help me understand...
