I have just committed into trunk a couple of changes that make easier to serialize a QObject instance to JSON.

This solution relies on the awesome Qt’s property system.

Suppose the declaration of Person class looks like this:

class Person : public QObject
{
  Q_OBJECT

  Q_PROPERTY(QString name READ name WRITE setName)
  Q_PROPERTY(int phoneNumber READ phoneNumber WRITE setPhoneNumber)
  Q_PROPERTY(Gender gender READ gender WRITE setGender)
  Q_PROPERTY(QDate dob READ dob WRITE setDob)
  Q_ENUMS(Gender)

public:
    Person(QObject* parent = 0);
    ~Person();

    QString name() const;
    void setName(const QString& name);

    int phoneNumber() const;
    void setPhoneNumber(const int  phoneNumber);

    enum Gender {Male, Female};
    void setGender(Gender gender);
    Gender gender() const;

    QDate dob() const;
    void setDob(const QDate& dob);

  private:
    QString m_name;
    int m_phoneNumber;
    Gender m_gender;
    QDate m_dob;
};

The following code will serialize an instance of Person to JSON:

Person person;
person.setName("Flavio");
person.setPhoneNumber(123456);
person.setGender(Person::Male);
person.setDob(QDate(1982, 7, 12));

Serializer serializer;
qDebug() << serializer.serialize( &person);

The generated output will be:

{ "dob" : "1982-07-12", "gender" : 0, "name" : "Flavio", "phoneNumber" : 123456 }

I hope you will find this new feature useful. I'm also considering to create a similar method inside the Parser class.

As usual suggestions are welcome.
