Jürgen, I'm sinking fast in a pile of poo. However I think that this gives me the paragraph that is currently visible at the top of the LyX screen. BufferView * bv = ...; // I have a cached copy of this. LyXText * text - bv->getLyXText(); int const top_y = text->first_y; Row * row = text->getRowNearY(top_y); Paragraph * par = row->par(); If that's right, then that's all I need. I'll just load all previews for insets in the 5 pars on either side of this using Paragraph::next() and Paragraph::previous(). Am I on the right track? Angus
