[Qt-interest] QSqlRelationalTableModel/QTableView delegate functions for row navigation

[Harry Sfougaris]

I would like to know if the user is trying to move to another row.
If the data is not valid, i want to be able to either force him to fix it, or cancel the edits. The events i have found (and the one you mention) don't seem to give you the ability to disallow moving to another row.

Thanks
