Subclass BaseTextDocument and reimplement the "save" method (do your stuff, then call BaseTextDocument::save). Set an instance of your BaseTextDocument subclass as the text document via BaseTextEditor::setBaseTextDocument. Have a look how that is used in other BaseTextEditor subclasses in Qt Creator.
