Hi, I couldn't really understand what information is stored inside the BufferView.offset_ref_ variable. At a first glance, it would seem that anchor_ref_ stores the "paragraph offset" that is displayed from the WorkArea top line, and offset_ref_ stores the "pixel offset". Namely, the top WorkArea line of pixels would display the offset_ref_-th line of the anchor_ref_-th paragraph.
Even if I keep these two values in sync with the scrollbar, it seems there are other variables that decide what pars the workarea starts displaying from the top. Moreover, what var decides how the gray text background is cut at the end of the doc ? Thanx, T.
