Serialize a C++ string in QDatastream

[Denarius]

hey,
I was wondering how I could serialize a c++ string into a QDatastream

something like this:

string myString = "hello";
someStruct.myString = myString;

string myString = "hello";
someStruct.myString = myString;

To copy to clipboard, switch view to plain text mode 

serialize via operator:

QDataStream& operator<< (QDataStream& out, const someStruct)
{
out << someStruct.myString;

QDataStream& operator<< (QDataStream& out, const someStruct)
{
out << someStruct.myString;

To copy to clipboard, switch view to plain text mode 

How do I serialize the string in the QDataStream.
Obviously the above doesn't work.
I need this for something but the Qt reference isn't helping me.

Does anyone know how to do this?
