[Qt-interest] Using QTextEdit in QItemDelegate

[Josh]

For what it's worth, you may try using a QTextDocument instead like this:

void HtmlDelegate::paint(QPainter *painter, const QStyleOptionViewItem & 
option, const QModelIndex & index) const
{
   QVariant value = index.data(Qt::DisplayRole);
   if (value.isValid() && !value.isNull())
   {
     QTextDocument document;
     document.setDocumentMargin(2);
     document.setHtml(value.toString());
     painter->translate(option.rect.topLeft());
     document.drawContents(painter);
     painter->translate(-option.rect.topLeft());
   }
}

This works well for me.
