How to return QVariant type array

Question

I am recently creating a model for qml with c++, but I face a problem when returning a QVariant type empty array. How should I define my return statement?

switch (role) {
case NameRole:
    return QVariant(QStringLiteral("AAAAA"));
case LevelRole:
    return QVariant(QStringLiteral("1"));
case ParentRole:
    return QVariant(QStringLiteral("null"));
case SublevelRole:
    return ???// I would like to return an empty array
}

Use QVariantList:

switch (role) {
case NameRole:
    return QVariant(QStringLiteral("AAAAA"));
case LevelRole:
    return QVariant(QStringLiteral("1"));
case ParentRole:
    return QVariant(QStringLiteral("null"));
case SublevelRole:
    return QVariantList();
}
