Qjson handling an returned array of ojbects - c++

Question

I'm using Qjson to parse a json object that is returned from a web service. I'm stuck on handling an array of complex ojects.
At the first level the web service returns a map consisting of "error", "id", and "return". If there are no errors I can get the first level value by using
nestedMap = m_jsonObject["result"].toMap();
group = new Group();
group->Caption = nestedMap["Caption"].toString();
group->CollectionCount = nestedMap["CollectionCount"].toInt();
I can even get a date item value that is at the second level using
group->ModifiedOn = nestedMap["ModifiedOn"].toMap()["Value"].toDateTime();
I have an object called "Elements" that consists of 29 key-value pairs. The web service is returning an array of these "Elements" and I am unable to find the right way to parse it. In the header file the container for the elements is defined as
QList<GroupElement> Elements;
The line
group->Elements = nestedMap["Elements"].toList();
causes the compiler to throw an error 'error: no match for 'operator=' in '((MyClass*)this)->MyClass::group->Group::Elements = QVariant::toMap() const()'
I would like to learn the correct syntax to put this element into the class.

Answer 1

Update: I wrote another function to convert the QVariantMap object to a
first:
The group-> Elements object was changed to a
class ParentClass{
QList<SharedDataPointer<Address> > Elements;
other class memmbers...
};
Second:
A method to convert the QMap object to an Address object was created
QSharedDataPointer<Address>
API_1_6::mapToAddress(QVariantMap o)
{
QSharedDataPointer<Address> address (new Address());
address-> FirstName = o["FirstName"].toString();
address->LastName = o["LastName"].toString();
address->CompanyName = o["CompanyName"].toString();
address->Street = o["Street"].toString();
address->Street2 = o["Street2"].toString();
address->City = o["City"].toString();
address->Zip = o["Zip"].toString();
address-> State = o["State"].toString();
address->Country = o["Country"].toString();
address->Phone = o["Phone"].toString();
address->Phone2 = o["Phone2"].toString();
address-> Fax = o["Fax"].toString();
address-> Url = o["Url"].toString();
address->Email = o["Email"].toString();
address->Other = o["Other"].toString();
return address;
}
third: In the code, foreach is used to walk through the list and create and store the new objects
// get the list of the elements
elementsList = nestedMap["Elements"].toList();
// Add the element, converted to the new type, to the Elements object of the'parent' class
foreach(QVariant qElement, elementsList){
group-> Elements.append(mapToAddress(qElement))
}
