[Interest] 5.8.0 QAbstractListModel

[mark diener]

Cannot use emit dataChanged(index(0),index(growcount-1)) to cause
re-display of changed
values in ListView.

Tried every combination:

emit dataChanged(index(grow),index(grow));
emit dataChanged(index(0),index(grows));
emit dataChanged(index(0),index(grows-1));

Only can repaint entire ListView with:

    this->beginResetModel();
    this->endResetModel();

But this is overkill,. I want to trigger the Model to update a single
row.

Anyone with ideas?
