QHash<QString, QVarant> to file

[weaver4]

I would like to serialize and deserialize a QHash<QString , QVariant> to a file. Is there an easy way to do this?

[weaver4]

How about something like this:


QHash<QString, QVariant> entries;

entries.insert("key1", 1);
entries.insert("key2", "seven");
entries.insert("key3", 22.7);

QFile fileOut("hashtest.dat");
if (fileOut.open(QIODevice::WriteOnly))
{
QDataStream out(&fileOut);
out.setVersion(QDataStream::Qt_4_6);

out << entries;
fileOut.flush();
fileOut.close();
}

QHash<QString, QVariant> inputs;

QFile fileIn("hashtest.dat");
if (fileIn.open(QIODevice::ReadOnly))
{
QDataStream in(&fileIn);
in.setVersion(QDataStream::Qt_4_6);

in >> inputs;

fileIn.close();
}

If it works, it's OK right?*





*Disclaimer: if it works it might still be wrong. It looks OK though.
