Thanks, can you show me what "modelData" is in your example, or how the .cpp side is laid out? I am using an Instantiator (and had been before I posted, based on something I stumbled across while searching for this), but I'm still missing some connection I need to make it work. 

Alternatively, this is my current code:
In main.cpp, I add three test items to the menu:
    QQmlEngine engine;
    QQmlComponent component(&engine, QUrl("qrc:/qml/dashboard.qml"));
    QObject* o = component.create();
    settingsModel *model = o->findChild<settingsModel *>("model");
    if (model)
    {
        qDebug() << "Adding items to model";
        model->insertRow(0, new QStandardItem("one"));
        model->insertRow(1, new QStandardItem("two"));
        model->insertRow(2, new QStandardItem("three"));
    } else {
        qDebug() << "Invalid data model";
    }

My settingsModel.cpp:
    class settingsModel : public QStandardItemModel
    {
        Q_OBJECT
    public:
        explicit settingsModel(QObject *parent = 0);

    private:
        QStringList mPorts;
    };

And then in my dashboard.qml:
    SettingsModel {
        id: settingsModel
        objectName: "model"
    }

    Menu {
        id: settingsMenu
        Instantiator {
            model: settingsModel
            onObjectAdded: {
                settingsMenu.insertItem(index, object)
                console.log("QML: object added: " + object.text + ", index= " + index);
            }
            onObjectRemoved: {
                settingsMenu.removeItem(object)
                console.log("QML: object removed: " + object.text);
            }
            
            delegate: MenuItem {
                text: "test"
            }
        }
    }

When I used your example verbatim, I got the error:
    qrc:///qml/dashboard.qml:93: ReferenceError: modelData is not defined
and I didn't get any menu items in the menu. When I run what I've attached, I do get a menu that has three entries, all labeled "test". Which makes sense based on what I have in there. So at least it seems like the calls to the model's insertRow() are triggering the Qml side to add items to the menu, but I just don't know what I'm supposed to change the text line below
            delegate: MenuItem {
                text: "test"
            }
To get the menu to pick up the model item's string for that item?
