Thank you for consideration.

Do you mean "overides getSurrounding() and deleteSurrounding()"?

How is each function implemented concretely?

How does QInputContext acquire cursor position and text at getSurrounding()?
Is getSurrounding() of QWidget (QLineEdit and QTextEdit) performed? 
Does QInputContext::deleteSurrounding() perform deleteSurrounding() 
of QWidget (QLineEdit and QTextEdit)?
