嗨，我已经创建了一个小部件来使用它QTableWidget

这个小部件是一个简单的QComboBox

class ComboDelegate(QtGui.QItemDelegate):
    """
    A delegate that places a fully functioning QComboBox in every
    cell of the column to which it's applied
    """
    def __init__(self, parent, options):

        QtGui.QItemDelegate.__init__(self, parent)
        self.options = options
        self.parent = parent

    def createEditor(self, parent, option, index):
        combo = QtGui.QComboBox(parent)
        combo.addItems(self.options)
        self.connect(combo, QtCore.SIGNAL("currentIndexChanged(int)"), self, QtCore.SLOT("currentIndexChanged()"))
        return combo

    def setEditorData(self, editor, index):
        editor.blockSignals(True)
        editor.setCurrentIndex(editor.currentIndex())
        editor.blockSignals(False)

    def setModelData(self, editor, model, index):
        self.parent.item(self.parent.currentRow(), 4).setText("%s Byte" % editor.currentIndex())
        model.setData(index, editor.itemText(editor.currentIndex()))

    #@QtCore.pyqtSlot()
    def currentIndexChanged(self):
        pass
        self.commitData.emit(self.sender())

当用户更改 的 Value 时ComboDelegate，该 Widget 会更新另一个单元格的值，该单元格是Size cell

self.parent.item(self.parent.currentRow(), 4).setText("%s Byte" % editor.currentIndex() # Size cell

在我的MainWindow班级中，当单元格更改时，我分配了一个插槽

self.Table.cellChanged.connect(lambda: self.change_xml_entry(self.Table))

change_xml_entry更新单元格时应该更新 xml 条目！当单元格直接从用户手动更新时它工作正常，但是当我的ComboDelegate类更新时Size cell，父 Widgetself.Table没有收到知道单元格已更改的信号，因此它不会更新 xml 条目
