    Witam!

    Zaprojektowałem dwa okienka okno1 i okno2 w Qt Designer.
    Nie chcę konwertować ich do pliku .py , gdyż chcę dodawać jeszcze elementy.
    Napisałem skrypt w pythonie (pyqt5) by otiwerać okienka.
    Niestety nie wiem ak przekazywać dane między okienkami.
    W moim przykładzie po wyborze z okna 1 z list widget - i wciśnięcia przyciszku add adress by wybranty elememt pokazał się w label w oknie 2 a po wprowadzeniu adresu w oknie 2 i zatwierdzeniu pokazał się w oknie 1.
    window1 -okno1.ui is:
    '''<?xml version="1.0" encoding="UTF-8"?>
    <ui version="4.0">
    <class>MainWindow</class>
    <widget class="QMainWindow" name="MainWindow">
    <property name="geometry">
    <rect>
    <x>0</x>
    <y>0</y>
    <width>800</width>
    <height>600</height>
    </rect>
    </property>
    <property name="windowTitle">

    My python script is:

    Skrypt odczytuje plik Ui z designera (script open ui files)

    import sys
    from PyQt5 import QtCore, QtGui, QtWidgets, uic
    from PyQt5.QtCore import pyqtSlot
    from PyQt5.QtWidgets import QDialog

    class Window2(QDialog):
    def init(self):
    super().init()
    uic.loadUi("/home/ewcia/PycharmProjects/Designer_ui/okno2.ui",self) #link to window 2
    self.pushButton.clicked.connect(self.akcja2)

    pyqtSlot()
    def akcja2(self):
        new_adres= self.lineEdit.text()
        # How to add this new address to Mywindow
    

    #---------------------------------------------------------------------------------------------------------

    class Mywindow(QtWidgets.QMainWindow):
    def init(self):
    super(Mywindow,self).init()
    uic.loadUi("/home/ewcia/PycharmProjects/Designer_ui/okno1.ui", self) #link to open okno 1 on my disk

        self.pushButton.clicked.connect(self.akcja1)
    pyqtSlot()
    def akcja1(self):
        #print("druga akcja Drugie Okno")
        self.okno2 = Window2()
        self.okno2.show()
    

    if name== "main":
    import sys
    app=QtWidgets.QApplication(sys.argv)
    window=Mywindow()
    window.show()
    sys.exit(app.exec_())
