I didn't mean to imply that the only information you can send is the identifier :) But even with just the identifier your use case (selective drag/drop handling) is still possible. You just get the identifier, get the object and check the object's type. If for whatever reason you don't want to do the object lookup in e.g. dragMoveEvent, just use a different MIME type for each object type.
