how to edit the Qlistwidget item on the contextmenu

Triomphe

I want to make three action in the listwidget contextmenu.
when I right click on the action that is named "rename"

        #右键菜单
        self.leftWidget.setContextMenuPolicy(Qt.CustomContextMenu)
        self.leftWidget.customContextMenuRequested.connect(self.myListWidgetContext)

    def myListWidgetContext(self,position):
        #弹出菜单
        popMenu = QMenu()
        creAct =QAction("新建分组",self)
        delAct =QAction("删除分组",self)
        renameAct =QAction(u'重命名', self)
        #查看右键时是否在item上面,如果不在.就不显示删除和修改.
        popMenu.addAction(creAct)
        if self.leftWidget.itemAt(position):
            popMenu.addAction(delAct)
            popMenu.addAction(renameAct)

        creAct.triggered.connect(self.CreateNewItem)
        renameAct.triggered.connect(self.RenameItem)
        delAct.triggered.connect(self.DeleteItem)
        popMenu.exec_(self.leftWidget.mapToGlobal(position))

    #创建新的分组
    def CreateNewItem(self):
        test =QListWidgetItem("test")
        test.setTextAlignment(Qt.AlignCenter)
        self.leftWidget.addItem(test)


    #删除分组
    def DeleteItem(self):
        self.leftWidget.takeItem(self.leftWidget.currentRow())

    #重命名分组
    def RenameItem(self):
        curRow =self.leftWidget.currentRow()
        item=self.leftWidget.item(curRow)

        item.setFlags(item.flags() | Qt.ItemIsEditable)
        self.leftWidget.openPersistentEditor(item)
