Yes, I do. And also the documentation. Search it!

here .. try this one:

Code:

---

void MainWindow::on_pushButton_clicked()
{
    QString file = "D:/hello.txt";
        QFile outputFile(file);
        outputFile.open(QIODevice::WriteOnly);
 
        QString str = "text inside file";
 
        if(!outputFile.isOpen())
        {
            //alert that file did not open
        }
 
        QTextStream outStream(&outputFile);
 
        outStream << str;
 
        outputFile.close();
 
//open text file to user
        QDesktopServices::openUrl(QUrl(tr("file:///D:/hello.txt")));
 
 
  }
