call function when close second windows

[Nezox212]

class Ui_first1(object):
 def setupUi(self, first1):
     first1.setObjectName("first1")
     first1.resize(380, 249)
     
     self.label = QtWidgets.QLabel(first1)
     self.label.setGeometry(QtCore.QRect(160, 80, 191, 71))
     self.label.setObjectName("label")

     self.retranslateUi(first1)
     QtCore.QMetaObject.connectSlotsByName(first1)

 def retranslateUi(self, first1):
     _translate = QtCore.QCoreApplication.translate
     first1.setWindowTitle(_translate("first1", "Form"))
     self.label.setText(_translate("first1", "first windows"))

 


class Ui_second2(object):
 def setupUi(self, second2):
     second2.setObjectName("second2")
     second2.resize(394, 300)
     self.label = QtWidgets.QLabel(second2)
     self.label.setGeometry(QtCore.QRect(50, 120, 191, 71))
     self.label.setObjectName("label")
     app.aboutToQuit.connect(self.closeEvent) # as I understand its bind close button

     self.retranslateUi(second2)
     QtCore.QMetaObject.connectSlotsByName(second2)

 def retranslateUi(self, second2):
     _translate = QtCore.QCoreApplication.translate
     second2.setWindowTitle(_translate("second2", "Form"))
     self.label.setText(_translate("second2", "second windows"))

 # need print text when user close second windows, but print when close firs windows
 def closeEvent(self,):
     print("close")

When a close second windows nothing happens, but when I close all windows and the function is called. I need to call function when close only second windows. How to fix it?

Hi and welcome to devnet,

You are modifying the wrong part of the code. The Ui_XXX classes are generated based on the .ui file you created with designer. They are not even widgets. You need to modify the widget code that uses the Ui_XXX classes.
