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.

Thanks for your answers.

That is weird, everything looks fine, are you sure it does not work for you? Because this main surely works for me, so I would look somewhere else for the source of your problem.

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

The code you provided is also almost the same as the one provided in detailed description of QTextStream so I am pretty sure, that the problem is elsewhere :)

Also note, that the file is not called Data but Data.txt and should be created/located in the directory from which the program was run (not necessarily the one where the executable is located).
