Hi Jan, the reason, that you cannot find anything related is most probably due to the concept of dock widgets in the sense of auxiliary widgets, where current focus from the application POV doesn't make much sense. But that isn't a problem, just reimplement focusInEvent and focusOutEvent in the tree views (or the container widget, you set with QDockWidget.setWidget()). Then track focus changes within the event handlers, which might send custom signals to your main widget or some such..
