如何使用QAbstractTableModel(模型/视图)将数据设置到QComboBox?

我希望能够设置 itemData 的 combobox 当使用 QAbstractTableModel data 方法

通常,当不使用模型时,可以这样执行:

# Set text and data
combobox.addItem('Some text', 'some item data')

# Retrieve data from selected
item_data = combobox.itemData(combobox.currentIndex())

如何做到这一点,但使用 QAbstractTableModel ?

我有一个 下拉列表框 ,我将模型设置为:

model = ProjectTableModel(projects)
combobox.setModel(model)

我的型号:

class ProjectTableModel(QtCore.QAbstractTableModel):

    def __init__(self, projects=[], parent=None):
        QtCore.QAbstractTableModel.__init__(self, parent)
        self._projects = projects

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

    def columnCount(self, parent):
        return 2

    def data(self, index, role):
        row = index.row()
        column = index.column()

        if role == QtCore.Qt.DisplayRole and column == 0:
            project = self._projects[row]
            name = project.name()
            id = project.id()  # <----- how to add this as itemData?
            return name
