Text file's content deleted every time program runs

[Julian]

Hi, I have to add information to a text file but every time I open the program the previous contents of the file are deleted. This is the code:

The following is what is defined in the QMainWindows builder. Where flow1 and file1 are pointers defined with the private label in QMainWindows class

 file1= new QFile ("Repairs and failures.txt");
 file1->open(QIODevice::WriteOnly);
 flow1= new QTextStream (file1);

The following is the code that is performed in a clicked event

    file1->atEnd();
    QDate date;
    QString fecha;
    fecha=date.currentDate().toString("dd.MM.yyyy");
    QString texto;
    texto=ui->textEdit->toPlainText();
    if(texto.size()>1)
    {

        (*flow1)<<fecha<<":"<<texto<<endl;

    }

What I'm doing wrong?

Thanks and regards

See flags QIODevice::OpenMode. With QIODevice::WriteOnly the device will be truncated if possible. What you want is QIODevice::Append.
