I created a class of MainWindow and a class of FirstParty which is a second form. I created a object of FirstParty with the name of firstPartyForm in MainWindow class but when i run my program it shows that the firstPartyForm is not defined do you mean FirstParty.

class Mainwindow(QMainWindow):
    def __init__(self):
        super(Mainwindow,self).__init__()
        loadUi("Part1.ui",self)
        #These 2 lines are used to put funnctions on close and minimize buttons.
        #self.MinimizeButton.clicked.connect(lambda: self.showMinimized())
        #self.CrossButton.clicked.connect(lambda: self.close())
        districts = ["Attock","Bahawalnagar","Bahawalpur","Bhakkar","Chakwal","Chiniot","Dera Ghazi Khan","Faislabad","Gujranwala","Gujrat","Hafizabad","Jehlam","Jhang","Kasur","Khanewal","khusab","Lahore","Layyah","Lodhran","Mandi Bahauddin","Mian Wali","Multan","Muzaffarabad","NankanaSab","Narowal","Okara","Pakpattan","Raheem Yar Khan","Rajanpur","Rawalpindi","Sahiwal","Sarghoda","Sheikhupura","Sialkot","Toba Tek Singh","Vehari"]
        print(len(districts))
        tehsils = Import2dFile("Tehsils.txt")
        print(tehsils)
        self.cmb_District.addItems(districts)
        def createFirstPartyForm():
            global firstPartyForm
            firstPartyForm = FirstParty()
            print(firstPartyForm.checkBox.text())
            firstPartyForm.show()
            #return firstPartyForm
        if self.cmb_District.currentText() == "Lahore":
            print("ls")
            print(str(self.cmb_District.currentText()))
            self.cmb_Tehsil.addItems(tehsils)
        self.firstParty.clicked.connect(createFirstPartyForm)
        first_party_data = firstPartyForm.buttonBox.clicked.connect(self.the_first_party_ok_button_was_clicked)
        def the_first_party_ok_button_was_clicked():
            first_party_data = firstPartyForm.isBothCheckBoxTick(firstPartyForm)
            return first_party_data 
        print(first_party_data)   
class FirstParty(QDialog):
    def __init__(self):
        super(FirstParty, self).__init__()
        loadUi("AddFirstParty.ui",self)
        name = self.lineEdit.text()
        cnic = self.lineEdit_2.text()
        Relation = self.comboBox.currentText()
        relationText = self.lineEdit_4.text()
        contact_no = self.lineEdit_5.text()
        email = self.lineEdit_6.text()
        address = self.lineEdit_7.text()
    def isBothCheckBoxTick(self):
        btn1 = self.stateChanged(self.checkBox.text())
        btn2 = self.stateChanged(self.checkBox_2.text())
        if btn1 == "checked" and btn2 == "checked":
            FirstPartyRecord = [self.name,self.cnic,self.Relation,self.relationText,self.contact_no,self.email,self.address]
            return FirstPartyRecord
        return None
    def stateChanged(self,button):
        if button == "Use This First Party in the Form":
            if self.checkBox.isChecked():
                return "checked"
            else:
                return "unchecked"
        elif button == "Through Power of Attorney":
            if self.checkBox_2.isChecked():
                return "checked"
            else:
                return "unchecked"

It is Line no 24 where i am using it

I think it is because you are not using self with firstPartyForm. Try self.firstPartyForm

CodePudding user response：

check your AddFirstParty.ui file, probably there is no firstPartyForm name
