PyQT 4 fnished() signal would not emit

Question

class Main(QtGui.QMainWindow):
    self.process = QtCore.QProcess(self)
    QtCore.QObject.connect(self.process,QtCore.SIGNAL("finished(int)"),self.processCompleted)

    def processCompleted(self):
        self.ui.statusText.setText("Finished")
    self.process.startDetached(command,arguments)

I am not able to get the finished signal emitted here. Can anybody help me here.

I have just discovered that above statement works fine with process.start. Any idea what to for startDetached() — Kunal Deo, Dec 09 '12 at 23:39

startDetached() is a static method, so it's not called on an object. Therefore, no object will ever end up emitting the finished signal either.
