QML Repeater should allow creation of objects

    Description

      Today, Repeater can create QQuickItems only. It would be very useful if it could also create Objects (i.e., QtObjects). The reason is that will allow C+-defined models to be passed to C+ from QML.

      The BirthdayParty example included in Qt, which demonstrates attached properties, uses default properties for Person declarations. It inlines three "Person"s line this:

       

      BirthdayParty {
    Person { }
    Person { }
    Person { }
}

       

      But given that you have a data source for each person, it's cleaner to define this dynamically using a Repeater, as in the below example:

       

      BirthdayParty {
    Repeater {
        model: 3
        Person {
        }
    }
}

      Unfortunately, Person is an QObject, so this does not compile/work.
