Signals, events and handlers (was: Errors in GTK Tutorial?)

Hi all,
is at last well known that event signal handlers should be declared and return
an int value that has the meaning to upward propagate the event signal when the
handler retun a false value or to stop further propagation if it returns other
than false.
I would like to be confirmed that this does not apply to signals, signal
handlers return type is and remain void.
