PyQt—QTableWidget中的checkBox状态判断

一、QTableWidget实现checkBox效果

利用QTableWidgetItem对象的CheckState属性，既能显示QCheckBox，又能读取状态

1table = QtGui.QTableWidget()
2checkBox = QtGui.QTableWidgetItem()
3checkBox.setCheckState(QtCore.Qt.Unchecked)
4table.setItem(i, 0, checkBox)

二、call some function when checkbox state change

1self.connect(self.table, QtCore.SIGNAL("itemClicked(QTableWidgetItem*)"), self.table_item_clicked)
2
3def table_item_clicked(self, QTableWidgetItem):
4        check_state = QTableWidgetItem.checkState()
5        row = QTableWidgetItem.row()
6        if check_state == QtCore.Qt.Checked:
7            if row not in self.delete_row:
8                self.delete_row.append(row)
9        elif check_state == QtCore.Qt.Unchecked:
10            if row in self.delete_row:
11                self.delete_row.remove(row)
