    Default drag and drop: drag item from QListWidget to desktop or any open directory

    Hi everyone!
    I have QListWidget who contains list of files path. This files i'm dropped from explorer,
    but i don't know how to implement drag and drop from QListWidget to the desktop or explorer.
    This is my try...
    Qt Code:
    1. void FileListWidget::startDrag()
    2. {
    3. if (currentItem()) {
    4. QByteArray data;
    5. QFile src(currentItem()->text());
    7. data = src.readAll();
    8. src.close();
    9. QMimeData *mime = new QMimeData;
    10. mime->setData("text/uri-list", data);
    12. QDrag *drag = new QDrag(this);
    13. drag->setMimeData(mime);
    14. drag->exec(Qt::CopyAction | Qt::MoveAction, Qt::CopyAction);
    15. }
    16. }
    To copy to clipboard, switch view to plain text mode 
    ... but it's not working (error when copying file). Please explain me, what should I do to solve this problem?

    P.S. Sorry for my bad English
