Issue with c++ model

[pkl]

I have class:

class diagSys : public QObject
{
    Q_OBJECT
    ...
    Q_PROPERTY(QList<QObject *> periphList READ periphList NOTIFY sysConfigChanged)
    ...

class diagSys : public QObject
{
    Q_OBJECT
    ...
    Q_PROPERTY(QList<QObject *> periphList READ periphList NOTIFY sysConfigChanged)
    ...

To copy to clipboard, switch view to plain text mode 

periphList is list of objects:

class BriefBlockInfoObject : public QObject
{
    Q_OBJECT
 
    Q_PROPERTY(char address READ address WRITE setAddress /*NOTIFY typeChanged*/)
    Q_PROPERTY(int id READ id WRITE setId /*NOTIFY textChanged*/)
    Q_PROPERTY(QString name READ name WRITE setName /*NOTIFY textChanged*/)
    ...

class BriefBlockInfoObject : public QObject
{
    Q_OBJECT

    Q_PROPERTY(char address READ address WRITE setAddress /*NOTIFY typeChanged*/)
    Q_PROPERTY(int id READ id WRITE setId /*NOTIFY textChanged*/)
    Q_PROPERTY(QString name READ name WRITE setName /*NOTIFY textChanged*/)
    ...

To copy to clipboard, switch view to plain text mode 

I wanna use periphList as model in qml. I export diagSys object:

view->rootContext()->setContextProperty(QLatin1String("DIAG"),
                                           &diag);

view->rootContext()->setContextProperty(QLatin1String("DIAG"),
                                           &diag);

To copy to clipboard, switch view to plain text mode 

From qml I use this:

Repeater {
                ...
                model: DIAG.dispList
                ...

Repeater {
                ...
                model: DIAG.dispList
                ...

To copy to clipboard, switch view to plain text mode 

But It causes an error "ReferenceError: Can't find variable: name/address/id"

But if I export like this:

view->rootContext()->setContextProperty("dispModel",
                        QVariant::fromValue(diag.dispList()));

view->rootContext()->setContextProperty("dispModel",
                        QVariant::fromValue(diag.dispList()));

To copy to clipboard, switch view to plain text mode 

and use as model dispModel:

Repeater {
                ...
                model: dispModel
                ...

Repeater {
                ...
                model: dispModel
                ...

To copy to clipboard, switch view to plain text mode 

it perfectly works.

How can I use as model property value of object, not object itself?
