QFile dialog to save a file

[A Former User]

QString path_file = QString("%1\\%2\\%3").arg(ROOT_ACQUISITION,cartella,text_file_da_copiare );
    QString path_nuovo= QString("%1\\%2").arg("C:\\cartella\\",nome_file);
    QDir dir;

    if (!dir.exists("C:\\cartella\\"))

    {
        dir.mkpath("C:\\cartella\\");

    }

//    if (QFile::exists(path_file))
//        QFile::remove(path_nuovo);

    //QFile::copy(path_file, path_nuovo);

    QList<QUrl> urls;
    urls << QUrl::fromLocalFile("C://Acquisizione");
    QFileDialog dialog;
    dialog.setSidebarUrls(urls);
    QFileDialog::getSaveFileName(&dialog,tr("Copia File"), path_file, tr("(*.txt)"), nullptr, QFileDialog::DontUseNativeDialog);
    dialog.exec();

I have to save a file that I select but when I choice the path an other window opens and the file isn't saved

Hi
QFileDialog::getSaveFileName
only gets a filename/path so it will not save anything for you.
so you need some code to save data.

@mrjj ok, so in this way I obtain the path that I choice to save?
then I can use:

QFile::copy(path_file, path_nuovo);

Yes. if the file you select should be copied to path_nuovo
