QDataStream overloading << and >>

[volcano]

The operators are fine.

The issue is that you are not writing your object into the stream but its pointer.

QFile file("test.txt");
if(file.open(QIODevice::WriteOnly ))
{
        QDataStream stream;
        stream.setDevice(&file);
        stream << *w; // dereference the pointer and write the actual object
        file.close();
}

QFile file("test.txt");
if(file.open(QIODevice::WriteOnly ))
{
        QDataStream stream;
        stream.setDevice(&file);
        stream << *w; // dereference the pointer and write the actual object
        file.close();
}

Thanks for spotting that for me..

As a recommendation: don't use QObject as a base class unless you need it. Here actual "value" type classes would likely better.
Currently you are leaking all entries in itemList

Will make sure to use QObject only if I need so.
I guess parenting the entries int the itemList will stop the leak. Correct me if i'm mistaken.
