slot_process_externalchanges

void dbe::MainWindow::slot_process_externalchanges ( )

The purpose of this method is to replay local changes after the database has been externally modified.

It is called when there is a callback from config layer.

The user is being given the option to ignore the external change and proceed without bringing his current database to a consistent state. This will cause the database to be overwritten when local changes are going to be applied.
