  • can you add an example? Is this a valid example for your question? You have an orderobject (=parent) with orderitems (children) and want to update the order total when an orderitem-quantity is changed? or are thinking of something completely different? Commented May 22, 2012 at 13:18
  • @k3b Yeah that's a valid example. Some information in the child has changed requiring the parent to do something. Commented May 22, 2012 at 13:23
  • just add some constructor parameters and reference data members to each child class. Commented May 22, 2012 at 23:00
  • Does the child need to know all about the parent, or would a simple delegate be sufficient? Commented Sep 14, 2013 at 12:48
