[Qt4] qdatastream/qstring serialization

[fabo]

hi,

using this sample code :

QString date = QDate::currentDate().toString("dd/MM/yy");
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out.setByteOrder(QDataStream::LittleEndian);
out.setVersion(QDataStream::Qt_4_0);

QString date = QDate::currentDate().toString("dd/MM/yy");
QByteArray block;
QDataStream out(&block, QIODevice::WriteOnly);
out.setByteOrder(QDataStream::LittleEndian);
out.setVersion(QDataStream::Qt_4_0);

To copy to clipboard, switch view to plain text mode 

* test 1 :

out << date.toAscii();  // size = 12
qDebug() << "size = " << block.size();

out << date.toAscii();  // size = 12
qDebug() << "size = " << block.size();

To copy to clipboard, switch view to plain text mode 

* test 2 :

out << qPrintable(date);  // size = 13
qDebug() << "size = " << block.size();

out << qPrintable(date);  // size = 13
qDebug() << "size = " << block.size();

To copy to clipboard, switch view to plain text mode 

* test 3 :

out << date; // size = 20
qDebug() << "size = " << block.size();

out << date; // size = 20
qDebug() << "size = " << block.size();

To copy to clipboard, switch view to plain text mode 

i expected to find (or would find) size = 8 like :
block[0] = 'd'
block[1] = 'd'
block[2] = '/'
block[3] = 'M'
block[4] = 'M'
block[5] = '/'
block[6] = 'y'
block[7] = 'y'

any clarifications for me ?

cheers,

Fathi
