ITfContextOwner interface (msctf.h)

  • Article

The ITfContextOwner interface is implemented by an application or a text service to receive text input without having a text store. An instance of this interface is obtained when the application calls the ITfSource::AdviseSink method.

Inheritance

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

Methods
