我的python程序有问题。这是一个简单的“数据库”管理器，您可以在其中填写表单，按一下按钮，然后将数据存储在QWidgetTable中。我的问题是添加产品的效果很好，但是编写新的删除功能时显示错误AttributeError: 'Ui_MainWindow' object has no attribute 'delete_product'
这是按钮和功能的代码片段：
from PyQt4 import QtCore, QtGui
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName(_fromUtf8("Menager"))
MainWindow.resize(1094, 600)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
self.addProduct = QtGui.QPushButton(self.centralwidget)
self.addProduct.clicked.connect(self.add_product)
self.deleteProduct = QtGui.QPushButton(self.centralwidget)
self.deleteProduct.clicked.connect(self.delete_product)
def add_product(self):
[...]
def delete_product(self):
[...]
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
MainWindow = QtGui.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
按钮和功能之间有很多代码，大多数是其他小部件和标签，但是所有缩进都是正确的。我对发生的事情一无所知
原始代码在这里：
