Description
Occurs when a component is about to be written to a stream.
OnFindAncestor allows the writer to explicitly specify the ancestor of a component when it is written to a stream. The WriteComponent method generates this event to override the value of the Ancestor property before writing a component to a stream.
OnFindAncestor is an event handler of type System.Classes.TFindAncestorEvent.
