Safety of emitting a signal with a reference

[Momergil]

then why bother with signals / slots ?

For improved code organization, of course (no reason to go including header files from classes not directly related to the one in which I'm emitting the signal just to call one of his methods!)

Yes, but most often the connection is made by code that is external to both sender and receiver, so neither can really rely on the direct connection.

Ok, so my turn-around solution flew away =( I guess I'll move to shared pointers after all (or including the header file and calling the method I want to use )

Thanks for your reply!
