Thanks a lot for the explanation and the links, I'm going to go through all this. I think the signal/slot system of Qt is very well designed actually (I had no problem with it in pure C++ applications), it's just my implementation while using QML which ended up being messy. I also had to refactor some parts due to Android not liking slots in one thread and signal emitter in another. Also it seems signals were sent in a particular order on desktop and a different order on Android. That's why I'm looking for a clean architecture which would allow me to know and reason about what's happening in the application.
