ITfUIElement interface (msctf.h)
The ITfUIElement interface is a base interface of the UIElement object and is implemented by a text service.
Inheritance
The ITfUIElement interface inherits from the IUnknown interface. ITfUIElement also has these types of members:
Methods
The ITfUIElement interface has these methods.
| ITfUIElement::GetDescription The ITfUIElement::GetDescription method returns the description of the UI element. |
| ITfUIElement::GetGUID The ITfUIElement::GetGUID method returns the unique id of this UI element. |
| ITfUIElement::IsShown The ITfUIElement::IsShown method returns true if the UI is currently shown by a text service; otherwise false. |
| ITfUIElement::Show The ITfUIElement::Show method shows the text service's UI of this UI element. |
Remarks
A text service may implement some other UIElement interface such as ITfCandidateListUIElement in the same object that can be obtained by QI. A text service may implement only the ITfUIElement interface to a UI object that does not have to be drawn by the application but the show status can be controlled by the application. A text service that is categorized by GUID_TFCAT_TIPCAP_UIELEMENTENABLED needs to implement ITfUIElement for any UI object.
