QScriptEngine import custom object

poucz

Hello,
I have problem with import custom object to the script.
In custom object is another custom object, and here is a problem.
I don't know where I do misstage...

Headers of two classes:

class PERSON: public QObject{
	Q_OBJECT
public:
	Q_PROPERTY(QString  name MEMBER name)
	PERSON(QObject * parent=nullptr):QObject(parent){}
	PERSON(const PERSON & other):QObject(other.parent()){
		name=other.name;
	}
	PERSON & operator=(const PERSON & other){
		name=other.name;
		return *this;
	}
	bool operator!=(const PERSON & other){
		return name==other.name?true:false;
	}
	QString name;
};
Q_DECLARE_METATYPE(PERSON)

class CITY: public QObject{
	Q_OBJECT
public:
	Q_PROPERTY(QString  cityName MEMBER cityName)
	Q_PROPERTY(PERSON  commander MEMBER commander)
	CITY(QObject * parent=nullptr):QObject(parent){}
	CITY(const CITY & other):QObject(other.parent()){
		commander=other.commander;
		cityName=other.cityName;
	}
	CITY & operator=(const CITY & other){
		commander=other.commander;
		cityName=other.cityName;
		return *this;
	}
	PERSON commander;
	QString cityName;
};
Q_DECLARE_METATYPE(CITY)

Here is code:

	CITY * city=new CITY(this);
	city->cityName="Prague";
	city->commander.name="Novak";
	QScriptEngine engine;
	QScriptValue objectValue = engine.newQObject(city);
	engine.globalObject().setProperty("city", objectValue);
	qDebug()<<"old City:"<<city->cityName<<" old Commander:"<<city->commander.name;
	qDebug()<<"SCRIPT OUT:"<<engine.evaluate("city.cityName='Brno';city.commander.name='Pepa';city.commander.name").toString();
	qDebug()<<"new City:"<<city->cityName<<" new Commander:"<<city->commander.name;

And here is an output:

old City: "Prague"  old Commander: "Novak"
SCRIPT OUT: "undefined"
new City: "Brno"  new Commander: "Novak"

So please could you help me?

Thanks!!

If I use:

Q_PROPERTY(PERSON * commander READ getCommander)

instead

Q_PROPERTY(PERSON  commander MEMBER commander)

Now It's working. Could anyone explain this mystery to me?
Only pointer to object is allowed to access to class member? Cannot be reference?
