Ah, I see. And we didn't have `string-pixel-width' in the olden days, so this would be a way to line stuff up without knowing that. And it's dynamic, so if you change the font (or instantiate on a different display/frame type), then things will still line up. OK, I can see how it could be useful now. --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
