Description

The ITOCBuddyEvents interface can be implemented as an outbound events interface by the Buddy of the TOCControl (e.g. the MapControl). You would only implement this interface if you are creating a control or object that can be a Buddy of the TOCControl. The TOCControl listens to this interface (as well as IActiveViewEvents) in order to refresh maps, layers and symbology, and to re-sync events.

For example, when a new map document is loaded into the MapControl the IActiveView object contained within the MapControl gets replaced. If the MapControl is 'buddied' to a TOCControl, the MapControl fires the ITOCBuddyEvents::ActiveViewReplaced event to the TOCControl. The TOCControl stops listening to events on the 'old' IActiveView object and starts listening to events on the 'new' IActiveView object contained within the MapControl. This ensures the TOCControl automatically reflects the maps, layers and symbology of the Buddy.
