IFPObserver interface
Interface for an object to observe other objects.
Declaration
IFPObserver = classDescription
IFPObserver is the interface an object must implement if it
wishes to receive change notifications from another object. The presence of
this interface will be checked when the object registers itself using
FPOAttachObserver. The change notifications arrive
because the
FPOObservedChanged method is called by the observed
object.See also
