Изменить раскладку визуальной клавиатуры

У меня есть класс Keyboard в котором рисуется клавиатура и класс KeyEvent, в котором визуализируется нажатие на клавиши. Мне нужно чтобы при нажатии на комбинацию alt + shift, поменялся язык на визуальной клавиатуре.

Пробовал полностью очищать клавиатуру, удаляя все элементы, но при вызове setupUI она не появляется.

Создал функцию которая удаляет всю клавиатуру и отрисовывает ее заново.

Так же переместил строку self.verticalLayout = QVBoxLayout(self) из stupUI() в инициализацию.

Теперь все прекрасно работает.

def change_layout(self):
    for i in self.findChildren(QFrame):
        i.setParent(None)
        del i

    self.switch = True
    self.setupUI()
