How customize items of ModelView?

Hello,
I'm french, sorry for my english.

I have a QSqlTableModel and a QTableView.

I want to customize items in my tableView.

Exemple, change the background color of a selected items with values 69:

Code:

---

QModelIndex id = tableView->currentIndex();
if (  model->data(id,Qt::DisplayRole) == 69 )
id->setBackground ( pink) ..... //SOMETHING THAT

---

Or , I want an icons near items with values = 69.

Subclass QSqlTableModel and reimplement QAbstractItemModel::data():

Code:

---

QVariant MySqlTableModel::data(const QModelIndex& index, int role) const
{
    QVariant val = QSqlTableModel::data(index, role);
    if (role == Qt::BackgroundRole && val == 69)
    {
        return QVariant::fromValue(QBrush(Qt::red)); // or QColor?
    }
    return val;
}

Similar approach works. Use QModelIndex::sibling() to test sibling items' values.

Another possibilities are to use a proxy model that will do that (reimplementing data() as suggested) or a custom item delegate that will paint the item in a different way (changing the background colour or adding an icon).

if instead of the QTableView would be a QListView what are the posibilities to change an item position ?

for example, when the mode in the list is Free you can move the items around in the widget so this tells me that items can be placed in a different position.

what i want to achieve to make all the items in a QListView \ QListWidget to be displayed at an offset from the default position ( i want to make them appear more to the right and down)

{ anwers to this post were moved to: custom painting in QListWidget }
