I've searched a bit, but could not found how to do this.

Have got a QSqlTableModel and a QTableView which I use to show the data.
I would like to know if, when I change the value of a field in QTableView, a signal is emitted, because I need to call a function when the user edit a field.

Don't care, now, to change the data directly in database, I'll do the commit manually.
