Just to complement my comment on Qt's event system, one place where it does play a central role in Qt's mental model is in Qt's concurrency framework. When covering that subject, the event loop and the different connection types are fundamental to understand how QObjects automagically communicate between themselves with Qt's signal-slots framework even when residing in different threads, or how Qt supports concurrency without requiring stuff to run on a separate thread.
