QListView sorting

[fear]

I've reimplemented compare in this way:

int KMListViewItem::compare(QListViewItem * i, int col, bool ascending) const
{
	qDebug("compare()");
 
	Q_UNUSED(i);
	Q_UNUSED(col);
	Q_UNUSED(ascending);
 
	return 0;
}

int KMListViewItem::compare(QListViewItem * i, int col, bool ascending) const
{
	qDebug("compare()");

	Q_UNUSED(i);
	Q_UNUSED(col);
	Q_UNUSED(ascending);

	return 0;
}

To copy to clipboard, switch view to plain text mode 

It should work but it doesn't (items are moved). I think the only solution is to use setSorting(-1) and then use QHeader's setSortIndicator.
