I realized that the wording above is both unfortunate and wrong. I
understand that there is a need for virtual functions, and Gtk indeed
provides them as well. But what is less clear to me is why there is a
distinction between "clicked" and "mousePressEvent", and why they are
implemented differently? Anyhow, that has nothing to do with the Py part of
PyQt which simply reflects the underlying API.
