got something to work... not perfect, but the icon will now keep aspect ration in the item. enjoy!!!

Qt Code: 
  1. #include <QStyledItemDelegate>
  2. #include <QPainter>
  3.  
  4. class ItemDelegate : public QStyledItemDelegate
  5. {
  6. public:
  7.     enum ItemDataRole { SubTextRole = Qt::UserRole + 100 };
  8.  
  9.     ItemDelegate(QObject *parent = 0) : QStyledItemDelegate(parent) {}
  10.     QSize sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const;
  11.     void paint(QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index) const;
  12. };
  13.  
  14. QSize ItemDelegate::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const
  15. {
  16.     QIcon icon = qvariant_cast<QIcon>(index.data(Qt::DecorationRole));
  17.     QString line1 = index.data(Qt::DisplayRole).toString();
  18.     //QString line2 = index.data(SubTextRole).toString();
  19.  
  20.     int textW = option.fontMetrics.width(line1);
  21.     QSize iconSize = icon.actualSize(option.decorationSize);
  22.  
  23.     return QSize(iconSize.width() + 4,
  24.                  iconSize.height() + 2 + option.fontMetrics.lineSpacing() * 2 + 4);
  25. }
  26.  
  27. void ItemDelegate::paint(QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index) const
  28. {
  29.     p->save();
  30.  
  31.     QString line1 = index.data(Qt::DisplayRole).toString();
  32.     QString line2 = index.data(SubTextRole).toString();
  33.  
  34.     QStyleOptionViewItemV4 opt(option);
  35.     initStyleOption(&opt, index);
  36.  
  37.     QStyle *style = opt.widget->style();
  38.     style->drawPrimitive(QStyle::PE_PanelItemViewItem, &opt, p, opt.widget);
  39.  
  40.     if (option.state & QStyle::State_Selected)
  41.         p->setPen(QPen(option.palette.brush(QPalette::HighlightedText), 0));
  42.  
  43.     QRect itemRect = option.rect.adjusted(2, 2, -2, -2);
  44.     QRect r = QStyle::alignedRect(opt.direction, Qt::AlignHCenter | Qt::AlignLeft, itemRect.size(), itemRect);
  45.     opt.icon.paint(p, r);
  46.  
  47.     int h = option.fontMetrics.lineSpacing();
  48.     QRect textRect(itemRect.left(), itemRect.bottom() - h, itemRect.width(), h);
  49.  
  50.     p->drawText(textRect, Qt::AlignVCenter | Qt::AlignHCenter, line1);
  51.  
  52.     QColor subTextColor = p->pen().color();
  53.     subTextColor.setAlphaF(.5);
  54.  
  55.     p->restore();
  56. }
