Как сделать переход между страницами в одном окне?

Рейтинг: 0Ответов: 1Опубликовано: 11.04.2023

Пытаюсь реализовать игру. Изначально мы попадаем в меню

Меню игры.

Дальше идёт развилка. Либо сразу начать игру или же настроить игру.

У меня идёт проблема с реализацией перехода между страницами. Начальную страницу и станицу настроек сделал в Qt Designer.

Я уже пробовал найти что-то в интернете, но безуспешно.
Прошу помощи. Заранее спасибо!

app = QtWidgets.QApplication([])
application = Intro()
application.show()

sys.exit(app.exec())`

    sys.exit(app.exec_())

Каким способом я могу перейти к настройкам?
