The ITfContextOwnerServices interface is implemented by the manager and used by a text service or application acting as context owners. The interface provides notification changes to sinks and other services to context owners that do not implement the ITextStoreACP or ITextStoreAnchor interfaces. Clients obtain this interface by calling the ITfContext::QueryInterface method.
Inheritance
