The MVC pattern dates back to the time when people actually had to write code for the "view" part. These days most people don't write code for this anymore (except for games and other graphical apps) but use a toolkit. In this case the Qt provides the view so the code where the user writes the signal handlers to handle signals such as button presses etc. is the controller. The view part doesn't need to be done.
