For these cases you must send a QKeyEvent and establish the focus after sending it:

def spacebar(self):
    key_event = QtGui.QKeyEvent(QtCore.QEvent.KeyPress, QtCore.Qt.Key_Space, QtCore.Qt.NoModifier, " ")
    QtCore.QCoreApplication.sendEvent(self.titleEdit, key_event)
    QtCore.QTimer.singleShot(0, self.titleEdit.setFocus)
