[Interest] Showing Icon and tooltip into QSqlQueryModel index

[Thales Lange]

Hi Michele.

I think you will need to inherit QSqlQueryModel and reimplement the method:

virtual QVariant data(const QModelIndex &item, int role =
Qt::DisplayRole ) const

When "item" is your table index and role == Qt::DecorationRole, you can
return the desirable icon.

I hope this solution might be useful!

Best Regards,
Thales Lange.
