Question

我正在使用PyQt5在Python GUI上工作，但出现错误“ AttributeError：'MainWindow'对象没有属性'cbWONum'”。如果我从QtDesigner导入.ui文件，则可以使其正常运行。但是，当我遇到此问题时，就要学会在Pycharm中创建自己的GUI。如果您可以查看我的代码并就我还是Python的新手给我做一个解释。感谢您的所有帮助。

from PyQt5 import QtWidgets, QtGui, QtCore
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from Controller import CustOrders as CO
import DBConnection as DB
import time
import sys


class MainWindow(QMainWindow):

listofCustOrders = []

def __init__(self, *args, **kwargs):
    super(MainWindow, self).__init__(*args, **kwargs)

    self.setWindowTitle("Paint Rack Log")

    cbCONum = QComboBox()
    self.setCentralWidget(cbCONum)
    self.gUI()



def gUI(self):
    global listofCustOrders

    listofCustOrders = CO.CustOrders.getCustOrders()

    for x in listofCustOrders:
        self.cbCONum.addItem(x.getCustOrderNO())

    cbCONum.currentIndexChanged.connect(self.coSelected)

def coSelected(self, text):
    cbCOIndex = self.cbCONum.currentIndex()
    selectedCO = listofCustOrders[cbCOIndex]


def main():
   import sys
   app = QtWidgets.QApplication(sys.argv)
   window = MainWindow()
   window.show()
   sys.exit(app.exec_())


if __name__ == '__main__':
   main()

跟踪如下：

Traceback (most recent call last):
 File "C:/Users/Documents/PyProjects/Launcher.py", line 51, in <module>
   main()
  File "C:/Users/Documents/PyProjects/Launcher.py", line 45, in main
   window = MainWindow()
  File "C:/Users/Documents/PyProjects/Launcher.py", line 23, in __init__
   self.gUI()
  File "C:/Users/Documents/PyProjects/Launcher.py", line 33, in gUI
    self.cbCONum.addItem(x.getCustOrderNO())
 AttributeError: 'MainWindow' object has no attribute 'cbCONum'
