Вопрос:
У меня проблема в процессе работы моего графического интерфейса. У меня есть 3 окна, которые являются главным окном -> 2-е окно -> 3-е окно, затем выйдите. Это хорошо работает при нажатии кнопки, переходящей во 2-е окно, но если я нажал кнопку в окне 3, она отключается.
Весь процесс завершается без сообщения о какой-либо ошибке.
Это мой код для первого окна:
from window2 import *
from window3 import *
class Ui_MainWindow(object):
def openWindow2(self):
self.window = QtWidgets.QMainWindow()
self.ui = Ui_MainWindow2()
self.ui.setupUi2(self.window)
MainWindow.hide()
self.window.show()
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(637, 309)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(230, 90, 341, 16))
self.label.setObjectName("label")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(520, 230, 75, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.openWindow2)
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
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_())
Это код для второго окна:
from window3 import *
class Ui_MainWindow2(object):
def openWindow3(self):
self.window = QtWidgets.QMainWindow()
self.ui = Ui_MainWindow3()
self.ui.setupUi3(self.window)
MainWindow.hide()
self.window.show()
def setupUi2(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(481, 242)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(340, 180, 75, 23))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.openWindow3)
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(210, 100, 61, 16))
self.label.setObjectName("label")
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow2()
ui.setupUi2(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Это код для третьего окна:
from window1 import *
from window2 import *
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_MainWindow3(object):
def setupUi3(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(397, 319)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.label = QtWidgets.QLabel(self.centralwidget)
self.label.setGeometry(QtCore.QRect(180, 110, 47, 13))
self.label.setObjectName("label")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(290, 250, 75, 23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow3()
ui.setupUi3(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
Может кто-нибудь сказать мне, почему процесс завершается во 2-м окне при нажатии кнопки и почему он не может перейти к 3-му окну?

Комментарии:
1. Спасибо сэру С.Нику, это работает, но как я могу закрыть окно 3, когда нажимаю кнопку 3? потому что я пытался сделать
def close(self): Mainwindow.close()
, но это не может закрыть окно 3? Как я могу это закрыть?2. Добавьте строку
self.pushButton.clicked.connect (MainWindow.close)
вwindow3.py
3. Спасибо, сэр, я действительно ценю помощь.
4. нужно ли мне комментировать все
self.retranslateUi(MainWindow)
? потому что это удаляет все компоненты, которые я использовал5. я все эти часы пытался внедрить это в свои системы, но это не работает.
