python - 第二个对话框窗口上的按钮不起作用

Question

我在 QT 设计器中创建了两个窗口。第一个有两个按钮，每个按钮都调用对话框窗口。我刚刚开始为此编写代码，但是当我测试对话框窗口上的按钮时，我无法更进一步。我刚刚连接到一个调用打印（“测试”）的函数，只是为了看看 PB 工作，但它不起作用。我错过了什么？

看下面的主要代码：

from PyQt5 import QtWidgets
from Main_VIEW import Ui_MainWindow # this is the main window
from Dialog_sa import Ui_Dialog # dialog window
from Test4 import currentAccount,savingAccount # this has all functions and calculations
import sys

class ApplicationWindow(QtWidgets.QMainWindow,Ui_MainWindow,Ui_Dialog,QtWidgets.QDialog):
    def __init__(self):
        super(ApplicationWindow, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        #self.diag_ui = Ui_Dialog()
        #self.diag_ui.setupUi(self)
        self.ui.pb_ca.clicked.connect(self.open_dialog_ca)


    def open_dialog_ca(self):
        #global dialog
        dialog = QtWidgets.QDialog()
        dialog.ui = Ui_Dialog()
        dialog.ui.setupUi(dialog)
        dialog.exec_()
        dialog.show()
        account = currentAccount()
        dialog.value_str = dialog.ui.le_b.text()
        dialog.ui.pb_d.clicked.connect(self.print_sel) # this is the line of code that doesn't work
    def print_sel(self):
        print("this app")


def main():
    app = QtWidgets.QApplication(sys.argv)
    application = ApplicationWindow()
    application.show()
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

这是 Dialog_sa
