Creating/writing into a new file in Qt

Question

I am trying to write into a file and if the file doesn't exist create it. I have searched on the internet and nothing worked for me.

My code looks currently like this:

QString filename="Data.txt";
QFile file( filename );
if ( file.open(QIODevice::ReadWrite) )
{
    QTextStream stream( &file );
    stream << "something" << endl;
}

If I create a text file called Data in the directory, it remains empty. If I don't create anything it doesn't create the file either. I don't know what to do with this, this isn't the first way in which I tried to create/write into a file and none of the ways worked.

Answer 1

Are you sure you're in the right directory?
Opening a file without a full path will open it in the current working directory. In most cases this is not what you want. Try changing the first line to

QString filename="c:\\Data.txt" or
QString filename="c:/Data.txt"

and see if the file is created in c:\
