如何将数据从一个窗口发送到另一个窗口

Question

我想我的问题是有答案的，但这是pyqt4的问题，我不知道出了什么问题。你知道吗

我在qt-desiger上开了两扇窗户。它们都是Ui类型的文件。 “nadrzedny”是主窗口，“dodaj”是第二个窗口。 “nadrzedny”有QlistWidget，它应该是“dodaj”窗口QLineEdit添加的列表项。 1如何使数据从“dodaj”窗口发送到“nadrzedny”窗口。 2有没有可能使一个点击按钮-分配功能 例如，将数据传递到“nadrzedny”窗口并将日期保存在 同一时间。你知道吗

py文件类型中的“nadrzedny”

我的计划是：

from PyQt5.QtWidgets import QDialog
import sys
from PyQt5 import uic


os.chdir('/home/konrad/Przyklad')                        #Scieżka domyślna do mojego pliku

class Window2(QDialog):                                  # Okno w którym     będę wpisywał dane nieruchomości
    def __init__(self):
        super().__init__()
        uic.loadUi('dodaj.ui', self)




class Ui(QtWidgets.QMainWindow):                         # Okno główne programu
    def __init__(self):
        super(Ui, self).__init__()
        uic.loadUi('nadrzedny.ui', self)

        self.pushButton.clicked.connect(self.okno2)       # zdefiniowany przycisk otwierajacy Window 2
        self.show()

    def okno2(self):
        self.w = Window2()
        self.w.show()

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Ui()
    sys.exit(app.exec_())

我刚把它打开，但我不知道如何将输入的文本从一个窗口发送到另一个窗口。你知道吗
