Access caller qml-Object from C++ Object

[wysota]

So you would recommend that emitting a signal and then handling the rest in a qml slot stuff I wrote above?!
Or is there another (cleaner/more recommended) way?

I have no idea what your code is meant to do so it is hard to suggest a good solution. I can only say that going from UI stuff to logic and then back to UI is likely a bad design.
