(It still needs it for the signal) (It still needs it for the signal) But what we can also do is connecting to any function or functor: QML is designed so that data can easily be passed to and from C++. You can use the classes in the Qt Declarative module to load QML objects from C++. In addition, QML and C++ objects can easily communicate using Qt signals and slots. There are a few reasons that you might want to mix QML and C++ in your app. Signals and slots is a language construct introduced also in Qt for communication between objects which makes it easy to implement the observer pattern while avoiding boilerplate code.
