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.

Simplifying working with Q_PROPERTY items

Once it is easy to define Q_PROPERTIES, you'll soon want to make using it easy, so I have developed some template functions to do the work. Here is a list of them:

/// A generic template for stream the properties of a Q_GADGET or QObject
template <class OT> QString DumpProperties (const OT &obj);

/// Stream the properties of a class to a QDataStream
template <class OT> QDataStream &operator<<(QDataStream &stream, const OT &obj);

/// Retrieve the properties from a QDataStream.
template <class OT> QDataStream &operator>>(QDataStream &stream, OT &obj);

/// Check that all of the properties of two objects of the same type match.
template <class T> bool ArePropertiesMatched(const T &left, const T &right);

/// Copy all of the properties from one instance to another.
