[Qt-interest] QSqlRelationalDelegate - changing value in QTableView

[Martin Brodbeck]

Hi all,

I have a database table, displayed in a QTableView, with a foreign key. The 
table is editable. In order to change the foreign key value, I use a 
QSqlRelationalDelegate. I can click on the table cell and change the value via 
the ComboBox, thanks to the delegate, so it works in principle. But the change 
is only stored in the database when I confirm the change with the Enter-key. 
Simply change the value and click somewhere else on the UI does show the new 
value, but it is not permanent.

Is this behaviour intended? It doesn't seem very user friendly to me, or am I 
doing something wrong?

Thanks a lot
Martin
