[Interest] Showing Icon and tooltip into QSqlQueryModel index

[Thales Lange]

Michele,

I attached an example. This example contains:
1) SQL script to create the schema.
2) Example code
3) A picture that shows the result (The example adds a warning icon and
a tooltip message on the first column).

The example uses the MySQL Driver.

Best Regards,
Thales Lange.
