Hi all,

QList<MeteoLocale> underList;

}@

and this is the error that return:

error: 'QObject::QObject(const QObject&)' is private

exist a some kind of metod to do this?

The copy constructor is private, thus you have to use pointers in your list.

@
QList<MeteoLocale *>

but i need to set value not pointer...

A QObject and it derivations are non-copyable (more specifically non-copy-constructible and non-assignable). The container classes, like QList, require a copyable type.

Therefore you cannot create a QList of QObject objects. You will have to create a QList of pointer to QObject (<code>QList<MeteoaLocale *> underList</code>).

To complete Lukas Geyer answer, the reason why QObject cannot be copied nor assigned is because they are considered individuals: they can have a name, a parent, children and connections. As copying these all would not make sense, it was made impossible.

Just allocate your objects with 'new' and fill your list with the returned pointers

Tanks to all guy, to solve i have decide to remove the QObject ensension and for interact whit QML i create another object whit the same property but extend QObject.

Tnx to all
