Dear Felix,<div><br></div><div>I think that Rheinhard has gathered better what you mean --- are you suggesting that you want to know where to break lines in the finished output (say .pdf) by being able to see a vertical line in the TeXworks .tex editor?</div>
<div><br></div><div>Under Windows there is a standard api (GetTextmetrics GetTextExtent32 etc and newer) for calculating the fonted effect of a portion of plain ASCII --- however this would not take into account any of the LaTeX packages that you were using or other effects, and would rely on .ttf or .otf (and perhaps .ps) fonts only.</div>
<div><br></div><div>Such a calculation could only produce a jagged or zigzag (sometimes disjointed?) line in a plain text editor like TeXworks, and even if it could pre-calculate any output justification -- would constantly be being redrawn, possibly resource intensive(?) and visually with its constant alterations, would be potentially quite distracting I suspect.</div>
<div><br></div><div>Just for clarity please --- where would you see this having a usefulness? What sort of situation?</div><div><br></div><div>Would LyX <a href="http://www.lyx.org/Screenshots">http://www.lyx.org/Screenshots</a> be closer to providing what you need?</div>
