I'm creating a diff/patch frontend similar to Kompare but using KTextEditor to display/edit source/destination files. In order to be able to sync the scrolling positions of the two Views and also to overlay diff indicators (see screenshot), I'm exposing the following:

• scrollPos: scrolls the View to a cursor position
• scrollColumns: scrolls the View to a column
• maxStartPos: returns the cursor position of the maximum vertical scroll position
• startLine: returns the first visible line in the View
• endLine: returns the last visible line in the View
• textareaRect: returns the View's text area rectangle excluding border, scrollbars, etc.

Already tested in my app. It works :)
