In other words, the “ui” instance on which the presenter operates can not be faked in a unit test. This is one of the advantages to using model/view/presenter and Qt fails to make this possible without some serious work on the part of the developer.

Signal/Slot is a widely used pattern, many frameworks have it built-in including Django, Qt and probably many others. If you have a standalone project then you probably don’t want to add a big dependency like PyQt or Django just for a Signal/Slot framework.

qt - connecting signal/slot across different threads
Qt for Beginners - Qt Wiki Qt was created with the idea of removing this boilerplate code and providing a nice and clean syntax, and the signal and slots mechanism is the answer. Signals and slots Instead of having observable objects and observers, and registering them, Qt provides two high level concepts: signals and slots . QQuickView.rootObject() issues, dynamic signal/slot ... After sleeping a night over it, it think it's even easier and safer to just export all classes which provide slots to the rootContext and allow to call them directly. You would circumvent the whole signal/slot mechanism (which is of course a not very qt'ish design approach), but i'm safe that the pointers will be around.

QT and Signals/Slots. On the whole, QT is an excellent framework. It is well- designed and documented, portable, performant, versatile and it offers a wide range of features. Not to mention, it introduced the innovative signals and slots paradigm as an implementation of the Observer pattern.
