PyQt QListView正在检索用户在中编辑的项之后的项

Question

我正在使用python3.3pyqt5。我有一个包含一些项目的QListView小部件。我想在用户双击项目并对其进行编辑时检索该项目，以便将其新值保存到数据库中。但我找不到任何像编辑完成或有用的信号。在

class MainWin(QtWidgets.QMainWindow):
    itemName = ""
    def __init__(self, inheritance=None):
        super(MainWin, self).__init__()
        self.ui=uic.loadUi("MainWin.ui", self)

        self.wordList = FileProc.WordStorage().readWordFile()

        self.showListView()
        self.itemName = ""

    def showListView(self, file = 'wordlist.db'):
        MainWin.wordList = FileProc.WordStorage().readWordFile(file)

        model = QtGui.QStandardItemModel(self.listView)

        for row in MainWin.wordList:
            item = QtGui.QStandardItem(row)
            model.appendRow(item)

        self.listView.setModel(model)

    def editWord(self):
        itemIndex = self.listView.selectedIndexes()
        MainWin.itemName = itemIndex[0].data()

我用这种方式显示列表。我想用editWord（）方法检索编辑过的单词。如何在listView中的项更改后执行editWord（）？在

当我使用模型视图编程时我更愿意做的事情。是生成模型而不是使用默认模型。在

class ListMOdel(QtCore.QAbstractListModel):
    def __init__(self , data=[] ,parent=None):
        QtCore.QAbstractListModel.__init__(self,parent)
        self.__data=data

    def rowCount(self ,parent):
        return len(self.__data)

    def data(self,index,role):

        if role == QtCore.Qt.DisplayRole:
            row=index.row()
            value = self.__data[row]
            return value

    def flags(self,index):
        return QtCore.Qt.ItemIsEditable |QtCore.Qt.ItemIsEnabled| QtCore.Qt.ItemIsSelectable

    def setData(self,index,value,role=QtCore.Qt.EditRole):
        if role == QtCore.Qt.EditRole:
            row= index.row()
            self.__data[row]=value
            return True
        return False

class MainWin(QtWidgets.QMainWindow):
    itemName = ""
    def __init__(self, inheritance=None):
        super(MainWin, self).__init__()
        self.ui=uic.loadUi("MainWin.ui", self)

        self.wordList = FileProc.WordStorage().readWordFile()

        self.showListView()
        self.itemName = ""

    def showListView(self, file = 'wordlist.db'):
        MainWin.wordList = FileProc.WordStorage().readWordFile(file)
        data=[]
        for row in MainWin.wordList:
            data.append(row)

        model = ListMOdel(data)
        self.listView.setModel(model)

这是一个定制模型的例子。setData函数更新值。在
