<![CDATA[lineEdit with a csv file]]>I would like to write on qlineedit and save them in a csv file the problem is the code overwrites the old write in the csv and writes the new one, any idea please

void Robot::on_pushButton_clicked()
{
QString note = QDateTime::currentDateTime().toString(QString("'%1/note de mission_'dd-MM-yyyy'.csv").arg(dossier));
QFile filenote(note);
if(filenote.open(QIODevice::WriteOnly | QIODevice:: Text)) {
QTextStream n (&filenote);
n<<"Date et l'heure"<<";"<<"Commentaire"<<"\n";
QString b = ui->lineEdit->text();
QString d=QDateTime::currentDateTime().toString(QString("''dd-MM-yyyy'_'hh:mm:ss'"));
n<<d<<";"<<b<<";"<<"\n";

}
}

That is why @Christian-Ehrlicher suggested you will want append mode when opening the file.
