[PYTHON] Gestire evento su pressione del tasto INVIO per passaggio a controllo

[supersqualo]

Come si può scrivere correttamente la funzione event per far si che, attraverso la pressione del tasto invio, si passi da una QLineEdit ad un altra? Posto uno snippet funzionante. Grazie

from PyQt5 import QtCore, QtWidgets, QtGui

class Ui_MainWindow(object):

    def setupUi(self, MainWindow):

        MainWindow.setObjectName("MainWindow")

        MainWindow.resize(193, 119)

        self.centralwidget = QtWidgets.QWidget(MainWindow)

        self.centralwidget.setObjectName("centralwidget")

        self.verticalLayout_2 = QtWidgets.QVBoxLayout(self.centralwidget)

        self.verticalLayout_2.setObjectName("verticalLayout_2")

        self.x = QtWidgets.QLineEdit()

        self.verticalLayout_2.addWidget(self.x)

        self.x1 = QtWidgets.QLineEdit()

        self.verticalLayout_2.addWidget(self.x1)

        MainWindow.setCentralWidget(self.centralwidget)

        self.statusbar = QtWidgets.QStatusBar(MainWindow)

        self.statusbar.setObjectName("statusbar")

        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)

        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):

        _translate = QtCore.QCoreApplication.translate

        MainWindow.setWindowTitle(_translate("MainWindow", "0"))

    def event(self, event):

        if event.type() == QEvent.KeyPress:

            if event.key() in (Qt.Key_Return, Qt.Key_Enter):

                self.focusNextPrevChild(True)

        return super().event(event)



if __name__ == "__main__":

    import sys

    app = QtWidgets.QApplication(sys.argv)

    MainWindow = QtWidgets.QMainWindow()

    ui = Ui_MainWindow()

    ui.setupUi(MainWindow)

    MainWindow.show()

    sys.exit(app.exec_())
