If only... but no, that's what I got now. As I said, it looks *almost* ok, just because the highlight color is pretty much the same as the "explorer" box border.
Just try with a different delegate, try drawing a pixmap or just text.

This should illustrate what I mean:

Qt Code:
  1. void ProgressBarDelegate::paint( QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index ) const
  2. {
  3. if( option.state & QStyle::State_Selected )
  4. {
  5. painter->fillRect( option.rect, option.palette.highlight() );
  6. }
  7. QStyledItemDelegate::paint(painter, option, index);
  8. }
