send To Next Receiver
The sending logic will be based on that supplied by the sender() function; however, if there is no sender, then QObject is checked for its own sender.
A QObject may or may not have a helper object that implements the QObjectSenderIfc interface. If this helper object is supplied it will be used to send the processed QObject to its next location for processing.
If the QObject does not have the helper object, then the nextReceiver property is used to determine the next location for the qObject.
Parameters
completed QObject
