QtWS17 - Inside The Qt Object Model, Simon Hausmann, The Qt Company

Programming your application with Qt means that you will sooner or later encounter the central QObject class, signal & slot connections, or generic properties. The object model makes it safe and easy to develop with components. In this session we will take a look at the implementation of these features. For example, how emitting a signal with one line of code results in calling the right slot elsewhere. This is even possible when the sender lives in a different thread than the receiver. In addition, we will learn how reading and writing properties works behind the scenes.
