Method Description
ITfSystemLangBarItem::SetIcon ITfSystemLangBarItem::SetIcon method
ITfSystemLangBarItem::SetTooltipString ITfSystemLangBarItem::SetTooltipString method


A system language bar menu is an object on the language bar that supports menu items added to it by third-partyextensions. The system item must support the ITfSource interface and support the IID_ITfSystemLangBarItemSink identifier in its ITfSource::AdviseSink implementation. The system item should also implement the ITfSystemLangBarItem interface. The system item uses the ITfSystemLangBarItemSink interface to enable the extension to add items.
