Version: unknown (using KDE 3.5.0, Kubuntu Package 4:3.5.0-0ubuntu0breezy1 breezy) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.12-10-686 The classical way to draw ER diagrams shows attributes as ellipses with primary keys underlined. To make sense of an ER diagram it is often necessary to see which attributes are primary keys. Umbrello's ER diagrams don't mark primary keys at all. Other programs show a key next to the attribute name, which would solve the problem as well. I'd suggest to just show the primary key attribute names underlined. Patch follows.

Created an attachment (id=13971) [details] patch to print primary keys underlined

Looks fine to me, please commit. Thanks for your work on the ER stuff - it's badly in need of improvement :)
