If you can read my code this QListWidget can drag drop multile items as icon.. and text
from attribute hotels sauna bar, ecc..

Qt Code: 
  1. class IconScroller : public QListWidget
  2. {
  3.      Q_OBJECT
  4. //
  5. public:
  6. IconScroller( bool enable = false , QWidget* parent = 0 )
  7. 	: QListWidget( parent )
  8. {
  9.      enableout = enable;
  10.      setSelectionMode ( QAbstractItemView::ExtendedSelection ); 
  11.      setAcceptDrops(true);
  12.      setDropIndicatorShown(false); 
  13.      if (enable) {
  14.        setDragEnabled(true); 
  15.      }
  16.      ///////setIconSize ( QSize(80,80));
  17. }
  18.  
  19. void mousePressEvent(QMouseEvent *event)
  20. {
  21.    if (enableout) {
  22.      QListWidgetItem *child = itemAt(event->pos());
  23.      if (!child) {
  24.      return;  
  25.      }
  26.      /* IcoLine = hotel attribut icon mit beschreibung in 6 sprachen und
  27.      int kategorie int id  + pixmap 30x30 */
  28.      IcoLine Io = child->data(Qt::UserRole).value<IcoLine>();
  29.  
  30.      QPixmap dragicon = Io.pix().scaledToWidth(Io.pix().width() * 3); /* zoom it */
  31.      /* TabIcone liste von IcoLine */
  32.      TabIcone dd;
  33.      dd.all_lines.append(Io);
  34.  
  35.      QList<QListWidgetItem *> tutti = selectedItems();
  36.  
  37.      for (int i=0; i<tutti.size(); i++) {
  38.         QListWidgetItem *pane = tutti[i];
  39.         IcoLine Iter = pane->data(Qt::UserRole).value<IcoLine>();
  40.         dd.all_lines.append(Iter);
  41.      }

  48.      drag->setMimeData(mimeData);
  49.      drag->setPixmap(dragicon);
  50.      ///////drag->setHotSpot(event->pos() - ????? ); //////  
  51.      /* make pixmap large and setHotSpot  not need */
  52.  
  53.      if (drag->exec(Qt::CopyAction | Qt::MoveAction, Qt::CopyAction) == Qt::MoveAction) {
