pyqt4 tableWidget cellChanged 的使用方法

ws00310976

在0，0 单元格 变动后，获取这个单元格的字符，在label中输出

部分代码如下：(请指点如何改动)
QtCore.QObject.connect(self.tableWidget, QtCore.SIGNAL(_fromUtf8("cellChanged(int,int)")), self.out)
QtCore.QObject.connect(self.action1, QtCore.SIGNAL(_fromUtf8("triggered()")), self.test)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
    def out(self, row, col):
        a=self.item(row, col).text()
        self.label.setText(a)
