После нажатия на checkbox можно нажать на f7 и текст кнопки измениться

Question

На форуме нашел вопрос связанный с checkbox я попробовал сделать такую функцию.

После нажатия на checkbox открывается такая возможность как - после нажатия клавиши F7 текст кнопки должен измениться на Hello, но если же галочка не стоит то эта функция не должна работать .

Как это сделать?

Попробуйте так:

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):

class ExampleApp(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)

        self.checkBox.stateChanged.connect(self.checkboxChanged)

    def checkboxChanged(self, state):  
        if not state:
            self.pushButton.setText("PushButton")

    def keyPressEvent(self, QKeyEvent):                                 
        if QKeyEvent.key() == QtCore.Qt.Key_F7 and self.checkBox.isChecked():
            self.pushButton.setText("Hello World")


if __name__=="__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = ExampleApp()
    window.show()
    sys.exit(app.exec_())

Update

А как сделать так - если я после того как я нажал F7 и после этого нажму еще раз F7 то текст обратно станет Pushbutton, пробовал через else:, не работает

После нажатия на checkbox можно нажать на f7 и текст кнопки измениться
