Exactly. Signals and slots are between instances. And I would like to autogenerate a "class diagram" displaying connections between signals and slots, _ignoring_ that very fact. If there is ever a connection made between an object of ClassA and an object of ClassB, then I want to show this connection in the diagram. Maybe to most, this doesn't seem like a very helpful feature, but to me it does. It would help me to get a _sketchy_ overview of the app, and I put ephasis on sketchy. Some apps are driven by signals triggering the execution of slots more than others, and sometimes it can be difficult to get a quick overview. But I take it from your answer that there isn't any such utility around, as such a diagram wouldn't be an entirely correct representation, so I won't keep looking.
