ITfCleanupContextDurationSink interface

-description

The ITfCleanupContextDurationSink interface is implemented by a text service to receive notifications when a context cleanup operation is performed. This notification sink is installed by calling ITfSourceSingle::AdviseSingleSink with IID_ITfCleanupContextDurationSink.

-inheritance

The ITfCleanupContextDurationSink interface inherits from the IUnknown interface. ITfCleanupContextDurationSink also has these types of members:

-remarks

A context cleanup occurs when:

• The text service is deactivated while a context is still on the context stack. This can occur when the active text service is changed or when the active language changes while the text service is active.
• ITfThreadMgr::Deactivate is called while a context is still on the context stack.

A text service can use the notifications of this interface to prevent itself from performing any context initialization during the context cleanup operation.
