def signal_accumulator_object_handled(hint, return_accu, handler_return, dummy)

A GSignalAccumulator that aborts the signal emission after the first handler to return a value, and returns the value returned by that handler. This is the opposite behaviour from what you get when no accumulator is specified, where the last signal handler wins.
