People, I have a QDataTable, I would like that when a value of the QDataTable was modified, the user I could not more modify, these values I am white.

Here he is form.

In the case above, if the user modified value e if it tried to modify an error message again would be shown. It would like to make this for the application and not for the database.

It is possible to block this with the QDataTable.
