writing to a text-file

[QtBros61]

I have made a simple qt4-app with Carbide ide.
In one of my functions i am trying to write some text to a text-file but it is not working. I added file name result.txt to the project in Carbide.

Here is the code:

QFile file("result.txt");
file.open(QIODevice::WriteOnly);
QDataStream out(&file);   // we will serialize the data into the file
out << QString("victory");   // serialize a string

QFile file("result.txt");
file.open(QIODevice::WriteOnly);
QDataStream out(&file);   // we will serialize the data into the file
out << QString("victory");   // serialize a string

To copy to clipboard, switch view to plain text mode 

I also have included <QFile> and <QDataStream> in cpp-file.

The program dosent show any errors but it dosent write anythink to the file.
