python - 在 QCompleter 激活调用时查找 QStandardItemModel 的索引

我正在使用 QCompleter 在 PyQt5 中编写一个带有编辑字段的 GUI，以允许用户从弹出列表中选择输入。该列表内置于 QStandardItem 中并提供给 QCompleter。当用户从弹出列表中选择一个项目时，我需要的是 QStandardItem 模型中的行的索引。

我尝试研究文档 https://doc.qt.io/qt-5/qcompleter.html并找到一个名为

的部分

迭代完成要检索单个候选字符串，请使用需要完成的文本调用 setCompletionPrefix() 并调用 currentCompletion()。

这对我来说没有用，因为我的 QStandardItem 模型中存在重复项目的风险，例如['猫，'猫'，'狗']。根据用户选择第一只猫还是第二只猫，有两个不同的 ID 与之关联。因此，获取用户选择的项目的 QStandardItem 模型的索引非常重要。 

self.model = QtGui.QStandardItemModel()

#Merge the lists Id, IdCompound, self.SCL_Name together using zip. Id, IdCompount are int, while self.SCL_Name is str

ziplist1 = list(zip(Id, IdCompound, self.SCL_Name))
ziplist2 = list(zip(Id, IdCompound, self.SCL_OtherNames))

#Append the fields in ziplist1 and ziplist2 into 
for name in ziplist1:
    row = list()
    for col in name:
        cell = QtGui.QStandardItem(col) #Has made sure that everything is a string
        row.append(cell)
    self.model.appendRow(row)

for name in ziplist2:
    row = list()
    for col in name:
        cell = QtGui.QStandardItem(col)
        row.append(cell)
    self.model.appendRow(row)

self.completer = QtWidgets.QCompleter()
self.completer.setModel(self.model)
self.completer.setCaseSensitivity(QtCore.Qt.CaseInsensitive)
self.completer.activated.connect(self.complete_excipient_input)
self.completer.setCompletionColumn(2)

我应该在 self.completer.activated.connect(self.complete_excipient_input) 中做什么才能获取与用户所选项目相对应的 self.model 中的索引？

编辑

我尝试运行@eyllanesc提供的代码示例，它工作正常。但是，当我将代码应用到我自己的代码中时，我收到错误消息，指出 QObject::connect: Cannot connect QCompleter::activated(QModelIndex) to 

(null)::onActivated(QModelIndex)

和 发生异常:类型错误 activate(QModelIndex) 和 onActivated() 之间的 connect() 失败

下面是我的代码。它在 QtDesigner 中生成，随后转换为 python 代码。

最佳答案

激活的信号是重载的，也就是说，它可以返回QString(默认情况下，在python str中)或QModelIndex。所以必须通过使用completer.activated [QtCore.QModelIndex].connect(...)来指示，获取QModelIndex你可以使用sibling方法获取兄弟，或者使用 itemFromIndex() 获取项目。方法。

您不应修改 Qt Designer 生成的类(1)，因为它不是窗口小部件，而应创建另一个继承相应窗口小部件的类(2) 并使用初始类来填充它。装饰器 @pyqtSlot() 只能像小部件一样在 QObject 中工作，在您的情况下 Ui_MainWindow 则不能，因此您会观察到该错误。

考虑到解决方案是:
