QAbstractListModel list property for item

alejandro_pnz

Hi all. I've use for QML model custom QAbstractListModel object:

class TaskModel : public QAbstractListModel
{
    Q_OBJECT
public:
    enum TaskRoles {
        IdRole = Qt::UserRole + 1,
        NameRole,
        TypeRole,
        LimitRole,
        StateRole,
        CollectModeRole,
        SuccessedActionsCountRole,
        FailedActionsCountRole,
        DelayFromRole,
        DelayToRole
    };

    TaskModel(QObject *parent = 0);
    TaskModel(const TaskModel& model);
    int rowCount(const QModelIndex & parent = QModelIndex()) const;
    QVariant data(const QModelIndex & index, int role = Qt::DisplayRole) const;
    QHash<int, QByteArray> roleNames() const;

    class Stats {
    public:
        Stats(uint successActionsCount, uint failedActionsCount):
            successActionsCount_(successActionsCount),
            failedActionsCount_(failedActionsCount){}

        uint successActionsCount() const;
        uint failedActionsCount() const;

        void setSuccessActionsCount(const uint &successActionsCount);
        void setFailedActionsCount(const uint &failedActionsCount);

    private:
        uint successActionsCount_;
        uint failedActionsCount_;
    };

    class Task
    {
    public:
        Task(uint id, QString name, QString type,
             uint limit, uint state,
             const Stats &stats,
              uint scheduleTimeInSeconds,
             uint delayFrom, uint delayTo);

        uint id() const;
        QString name() const;
        QString type() const;
        uint limit() const;
        uint state() const;
        uint accountCount() const;
        uint delayFrom() const;
        uint delayTo() const;

        void setState(const uint &state);
        void setDelayFrom(const uint &delayFrom);
        void setDelayTo(const uint &delayTo);

        Stats stats() const;
        void setStats(const Stats &stats);

    private:
        uint id_;
        QString name_;
        QString type_;
        uint limit_;
        uint state_;
        Stats stats_;
        uint delayFrom_;
        uint delayTo_;
    };
    typedef std::shared_ptr<Task> TaskPtr;

    void addTask(const TaskPtr &task);
    void removeTask(int id);    
    void updateTask(int id, const Task& task);

    QList<TaskPtr> tasks() const;

private:
    QList<TaskPtr> tasks_;
};
}
Q_DECLARE_METATYPE(view::TaskModel)

The model works fine. But now I need to add a new property to the Task item - list of objects (e.g. list of Account).
I've tried use Q_PROPERTY, QQmlListProperty, QVariant with QList of Account. Two first variants returns undefined in QML-side, in last variant I can't get value of QVariant (console.log of this element of the model returns something like "QVariant(Qlist::account)' - returns undefined.
How can I set this list property?

Now solved:
Just use QVariantList with QVariantMap as values:

        QVariantList extendedStats;
        QVariantMap userAlreadySent, userAlreadyInGroup;

        userAlreadySent.insert("name", "Already sent");
        userAlreadySent.insert("value",  eventStats->userAlreadySent());

        userAlreadyInGroup.insert("name", "Already in group");
        userAlreadyInGroup.insert("value", eventStats->userAlreadyInGroup());

        extendedStats << userAlreadySent << userAlreadyInGroup;
