[Qt-qml] QML Slot

[Ivan De Marino]

(trying to bring back the main topic of this thread)

I think you can't connect to signals like that if you DON'T use a
Q_PROPERTY() macro.

At least in my experience, I never managed to connect to a signal into QML,
if not the ones that are related to Q_PROPERTY-ies.

If anyone finds a solution to this, I'm interested as well.
