    Hello,
    I have a problem with saving data from lineEdit end etc. to txt File.

    @void MainWindow::on_pushButton_2_clicked()
    {
    QString fileName = QFileDialog::getSaveFileName(this, tr("Zapisz plik"), "",
    tr("Plik tekstowy (.txt);;Plik C++ (.cpp *.h)"));

     if (fileName != "") {
         QFile file(fileName);
         if (!file.open(QFile::WriteOnly | QFile::Text)) {
             // error
         } else {
             QTextStream stream(&file);
             stream.setIntegerBase(10);
             stream << "Czas: " << timeEdit->time().toString() << "\n\n";
             stream << "Data: " << dateEdit->date().toString() << "\n\n";
             stream << "Miejsce: " << lineEdit->text() << "\n\n";
             stream << "Temat: " << lineEdit_2->text() << "\n\n";
             //stream << "Wiadomosc: " << textEdit-> << "\n\n";
             stream.flush();
             file.close();
         }
     }
    

    }@

    Content of .txt file:


    Czas:

    Data: 0x4

    Miejsce: 0x22fe48

    Temat: 0x40bab2

    Wiadomosc: 0x0

      What happens when you use QFile::write() instead of a stream?

        Error:

        'Write' is not a member of 'QFile'

            the code of your first post works fine for me.
            Try adding the following line:
            @
            stream.setCodec("UTF-8");
            @
