PyQt4 AttributeError：'function'对象没有'self'属性

Question

我无法从主程序更改GUI表中的值。我得到一个错误

AttributeError: 'function' object has no attribute 'commandTable'

我已阅读并尝试解决此问题中显示的解决方案，它不起作用。

AttributeError: 'function' object has no attribute 'self'

我应该在我的代码更改为获取代码工作？

主要代码：

import sys 
from PyQt4 import QtCore, QtGui 

from GUI_Window import * 


class MyForm(QtGui.QMainWindow): 
    def __init__(self, parent=None): 
     QtGui.QWidget.__init__(self, parent) 
     self.ui = Ui_MainWindow() 
     self.ui.setupUi(self) 
     self.ui.setupUi.commandTable.setItem(0,0, QtGui.QTableWidgetItem('1')) 

if __name__ == "__main__": 
    app = QtGui.QApplication(sys.argv) 
    myapp = MyForm() 
    myapp.show() 
    sys.exit(app.exec_()) 

GUI代码

try: 
    _fromUtf8 = QtCore.QString.fromUtf8

    self.centralwidget.setObjectName(_fromUtf8("centralwidget"))

    self.table.setObjectName(_fromUtf8("table")) 
    self.table.setColumnCount(0) 
    self.gridLayout.addWidget(self.table, 0, 0, 1, 1) 
    self.label = QtGui.QLabel(self.centralwidget) 
    self.label.setObjectName(_fromUtf8("label")) 
    self.gridLayout.addWidget(self.label, 2, 0, 1, 1) 
    self.progressBar = QtGui.QProgressBar(self.centralwidget) 
    self.progressBar.setProperty("value", 24) 
    self.progressBar.setObjectName(_fromUtf8("progressBar")) 
    self.gridLayout.addWidget(self.progressBar, 2, 1, 1, 1) 
    self.commandTable = QtGui.QTableWidget(self.centralwidget) 
    self.commandTable.setEnabled(True) 
    self.commandTable.setAlternatingRowColors(False) 
    self.commandTable.setRowCount(2) 
    self.commandTable.setColumnCount(10) 
    self.commandTable.setObjectName(_fromUtf8("commandTable")) 
    self.commandTable.setItem(0,0, QtGui.QTableWidgetItem('hi')) 
    self.commandTable.horizontalHeader().setCascadingSectionResizes(False) 
    self.commandTable.horizontalHeader().setSortIndicatorShown(False) 
    self.commandTable.horizontalHeader().setStretchLastSection(False) 
    self.commandTable.verticalHeader().setCascadingSectionResizes(False) 
    self.gridLayout.addWidget(self.commandTable, 1, 0, 1, 2) 
    MainWindow.setCentralWidget(self.centralwidget) 
    self.menubar = QtGui.QMenuBar(MainWindow) 
    self.menubar.setGeometry(QtCore.QRect(0, 0, 821, 18)) 
    self.menubar.setObjectName(_fromUtf8("menubar")) 
    MainWindow.setMenuBar(self.menubar) 
    self.statusbar = QtGui.QStatusBar(MainWindow) 
    self.statusbar.setObjectName(_fromUtf8("statusbar")) 
    MainWindow.setStatusBar(self.statusbar) 
    self.retranslateUi(MainWindow) 
    QtCore.QMetaObject.connectSlotsByName(MainWindow) 

def retranslateUi(self, MainWindow): 
    MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None)) 
    self.label.setText(_translate("MainWindow", "TextLabel", None)) 

遗憾的是最后一部分的心不是很好格式化

你试着打电话给你commandTable上setupUi()方法。这是一种方法，所以它没有任何这样的属性。请尝试：

self.ui.commandTable.setItem(0,0, QtGui.QTableWidgetItem('1')) 

在您的MyForm.__init__()方法中。包含对元素的引用的对象是self.ui，而不是其方法。
