Drag&Drop

I have custom QTableWidget, how drop lines from table to file system? File to program workd perfect

void ArchiveQTableWidget::dragEnterEvent(QDragEnterEvent *event)
{
    if (event->mimeData()->hasUrls()) {
        event->acceptProposedAction();
    }
}

void ArchiveQTableWidget::dragMoveEvent(QDragMoveEvent *event)
{
    event->acceptProposedAction();
}

void ArchiveQTableWidget::dragLeaveEvent(QDragLeaveEvent *event)
{
    event->accept();
}

void ArchiveQTableWidget::dropEvent(QDropEvent *event)
{
    foreach (const QUrl &url, event->mimeData()->urls()) {
        QString fileName = url.toLocalFile();
        qDebug() << "Dropped file:" << fileName;
    }
}

void ArchiveQTableWidget::startDrag(Qt::DropActions supportedActions)
{
    qDebug() << supportedActions;
    QFile qf("1.txt");
    qf.open(QFile::WriteOnly);
    qf.write(QByteArray("dasdasdwqdd"));
    qf.close();
    QMimeData *mimeData = new QMimeData;
    mimeData->setUrls(QList<QUrl>() << QUrl(QFileInfo("1.txt").absoluteFilePath()));
    QDrag *drag = new QDrag(this);
    drag->setMimeData(mimeData);
    drag->exec(Qt::CopyAction | Qt::MoveAction, Qt::CopyAction);
}

Hi and welcome to devnet,

Looks a bit like this stack overflow question.

Hope it helps

I found solution for one file, how copy more that one file?

        QString filename = "1.txt";
        QMimeData* mimeData = new QMimeData;
        FILEGROUPDESCRIPTOR desc;
        desc.cItems = 1;
        desc.fgd[0].dwFlags = FD_PROGRESSUI;
        wcscpy_s(desc.fgd[0].cFileName, filename.toStdWString().c_str());
        // make a deep copy here
        mimeData->setData("FileGroupDescriptorW", QByteArray((const char*)&desc, sizeof(FILEGROUPDESCRIPTOR)));
        mimeData->setData("FileContents", QByteArray("whatadjsaofhniewfnj"));
        QDrag *drag = new QDrag(this);
        drag->setMimeData(mimeData);
        drag->exec(Qt::CopyAction | Qt::MoveAction);
