PyQt - Open the same page several times

Question

I want, from my Index.py page, to open several times the page Form.py. For the moment when i try to open Form a second time the first Form page closes.

There is my Index.py code :

from PyQt5 import QtCore, QtGui, QtWidgets
from Form import Ui_FormWindow

class Ui_MainWindow(object):

    #The function to open the Form.py
    def open(self):
        self.window = QtWidgets.QMainWindow()
        self.ui = Ui_FormWindow()
        self.ui.setupUi(self.window)
        self.window.show()


    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(230, 180, 93, 28))
        self.pushButton.setObjectName("pushButton")

        self.pushButton.clicked.connect(self.open)

        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

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

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "PushButton"))


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_())

And here is the page i want to open several times, Form.py :

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_FormWindow(object):
    def setupUi(self, FormWindow):
        FormWindow.setObjectName("FormWindow")
        FormWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(FormWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.lineEdit = QtWidgets.QLineEdit(self.centralwidget)
        self.lineEdit.setGeometry(QtCore.QRect(250, 190, 113, 22))
        self.lineEdit.setObjectName("lineEdit")
        FormWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(FormWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 26))
        self.menubar.setObjectName("menubar")
        FormWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(FormWindow)
        self.statusbar.setObjectName("statusbar")
        FormWindow.setStatusBar(self.statusbar)

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

    def retranslateUi(self, FormWindow):
        _translate = QtCore.QCoreApplication.translate
        FormWindow.setWindowTitle(_translate("FormWindow", "FormWindow"))
        self.lineEdit.setText(_translate("FormWindow", "Page to open"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    FormWindow = QtWidgets.QMainWindow()
    ui = Ui_FormWindow()
    ui.setupUi(FormWindow)
    FormWindow.show()
    sys.exit(app.exec_())

I checked this answer but i don't understand how to make it work in my code. I also edited my question in order to be a minimal reproducible example but my english is not perfect and i fear to not understand perfectly what i read on the mre tutotial so sorry

Have you read that it is an MRE ?, your code is not so if you want help provide it, when you do let me know — eyllanesc, Oct 02 '19 at 18:50
@eyllanesc done but my english is not very great and i don't know if i understand perfectly what it is so sorry if it's not what you want — Dorian Daval, Oct 02 '19 at 19:20
1) add `self.ws = []` in `setupUi()` of Index.py 2) change to `def open(self): w = QtWidgets.QMainWindow() ui = Ui_FormWindow() ui.setupUi(w) w.show() self.ws.append(w) self.window.show()` — eyllanesc, Oct 02 '19 at 19:50

I haven't done QT stuff in a while but could it be the fact that you're instancing QtWidgets.QMainWindow again? That'd be my first guess.
