How to show multiple multi-line HTML texts in a QListWidget

I have a plan to show multiple multi-line HTML texts in a QListWidget with each multi-line HTML text in each row item.

1) With Item delegate my problem is on sizeHint - can it change as per each item text size? Can each item contain HTML multiline-text? Please help with code.
QSize ListDelegate::sizeHint ( const QStyleOptionViewItem & option, const QModelIndex & index ) const
{
return QSize(fixed as per item width, to vary as per multi-line text length which is aligned-justified);
}
2) Another heavy by simple solution is with QLabel as an WidgetItem for the QListWidget, but as soon I set HTML text in QLabel the item becomes unclickable.

Please help with some code.

Have you tried the suggestion you've got in the other thread were you posted the same question?

Cheers,
