A realisation can only connect to an abstract class in Umbrello
1.1.1.  Double click on the class and set it to absrtact.  Umbrello
1.2 will have/has proper Interface widgets to make this clearer.

I did some tidying up at Nove Hrady which should make this possible.
Boxes for signals and qt slots and signals would also be nice.
I doubt I can add it before the feature freeze though, it's tomorrow.
