In Qt, that's solved by using layout items that contain and manage other 
items, instead of using cross-inheriting (the latter arguably being a better 
solution). You still need to solve the problem with missing geometry 
accessors in QGraphicsItem, though.

Do you need to support regular graphics items in layouts, btw? Isn't it much 
easier to define a base Widget item?
