OK, that works: (but it does not look like good style, does it?)

QtCore.QObject.connect(self.lineEdit,QtCore.SIGNAL("returnPressed()"),self.blabla)

def blabla(self):
	#some code
        self.lb_ergebnis.setText(myString)

#---------

QtCore.QObject.connect(self.lineEdit,QtCore.SIGNAL("returnPressed()"),
		self.lb_ergebnis, QtCore.SLOT(setText(self.blabla)))
def blabla(self):
	#some code
        return myString

mmhhh ...

how can i pass an argument to the slot-name?


thanks for any hint
