+\brief A proxy class forwarding calls from QInputContext to HbInputMethod
 
 This class is needed because Qt's input context system assumes the ownership
 of the installed context and deletes the old one when a new context is installed.
-HbInput framework wants to cache active input context entities to its local

 This class is not needed outside of framework code.
