Показать и скрыть \ закрыть окна с пользовательскими аргументами, используя PyQt5

0 голосов
/ 19 ноября 2018

Я пишу приложение с графическим интерфейсом с помощью Qt Designer.Приложение состоит из нескольких окон, поэтому, когда пользователь нажимает кнопку в одном окне, должно открыться следующее окно, а текущее окно должно скрыться.Я достиг этой функции для перехода из окна 1 в окно 2. Но я не могу сделать это, чтобы перейти от окна 2 к окну 3. Я думаю, что это может быть потому, что окно 2 получает аргументы пользователя.

Есть ли способ скрыть окно, которое получает пользовательские аргументы?

Код выглядит следующим образом:

Класс для главного окна:

class MainWindow(object):

        self.user_data_window = QtWidgets.QMainWindow()

        self.next_window.setupUi(self.user_data_window)
        main_window.hide()
        self.user_data_window.show()

    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(640, 480)
