There are a couple of ways you can "plumb" devices and objects together. For devices you can use a qdev bus if you have a strict parent/child relationship between A and B. Or you can use a "link" property to manually wire up the devices/objects. Or use can use object composition (device A creates a child object B). But I think it depends a lot on what you are actually modeling and you are not sharing a lot of information on that ;) [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 488 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
