Hello,

How do I change the color of the text in a QListViewItem?  Is there an easy 
way, or do I have to reimplement QListView::paintCell() ?

Thanks,
Zach Hobbs

we had it working by sub classing QListViewItem and reimplement its 
paintCell() as in the follows,

void QxViewItem::paintCell(QPainter * p, const QColorGroup & cg, int column, 
int width, int align)
{
   QColor color;
   switch (type)                         //  type is a member of the item 
   {
      case 'B':
                color = QColor(0, 0, 255);
                break;
      case 'R':
                color = QColor(255, 0, 0);
                break;
      default:
                color = QColor(0, 0, 0);
   }

   QColorGroup _cg( cg );
   QColor oldColor = _cg.text();
   _cg.setColor(QColorGroup::Text, color);
   QListViewItem::paintCell( p, _cg, column, width, align );

   _cg.setColor(QColorGroup::Text, oldColor);
}
