[solved] qobjectlist-based model explanation

[spode]

@
class DataObject : public QObject
{
Q_OBJECT

 Q_PROPERTY(QString name READ name WRITE setName NOTIFY nameChanged)
 Q_PROPERTY(QString color READ color WRITE setColor NOTIFY colorChanged)
 ...

};

int main(int argc, char ** argv)
{
QApplication app(argc, argv);

 QList<QObject*> dataList;
 dataList.append(new DataObject("Item 1", "red"));
 dataList.append(new DataObject("Item 2", "green"));
 dataList.append(new DataObject("Item 3", "blue"));
 dataList.append(new DataObject("Item 4", "yellow"));

 QDeclarativeView view;
 QDeclarativeContext *ctxt = view.rootContext();
 ctxt->setContextProperty("myModel", QVariant::fromValue(dataList));
 ...

@

if i wrote this so:
@
Q_PROPERTY(QString name READ *get_*name WRITE setName NOTIFY nameChanged)
@
what should i write to obtain the same result?

now here:
@
class DataObject : public QObject
{
Q_OBJECT

 Q_PROPERTY(QString name READ name WRITE setName NOTIFY nameChanged)
 Q_PROPERTY(QString color READ color WRITE setColor NOTIFY colorChanged)
 ...

};
@
should i write a DataObject.cpp with the constructor? do you declare an explicit constructor in the header file DataObject.h? how do you write the constructor in this case?
must i declare QString name and QString color as variables in the header file DataObject.h?

solution: i MUST write the constructor; yes, i must declare an explicit constructor of the class, to inizializate variabols and so on; yes, i must declarare all the variables i have used in Q_PROPERTYs in the header.
