The slots are the handlers.  

In the parlance of the Design Patterns book, signals are the Notify() calls in the subject.  Slots are the corresponding methods in the observer.

connect() is how you attach a slot of a given observer to a signal of a given subject.

It sounds like you need to do it the other way around from what you did:  the slots should be the virtual methods in the observers.
