self.sender() never return instance of QProcess in the destroyed slot of QProcess, anyone can explain why ?


my code almost looks like the following 


process = QProcess(self) 
process.destroyed.connect(self.onProcessDestroyed)


def onProcessDestroyed(self):
    process = self.sender()
    print('onProcessDestroyed---------', process)
