Doh! I was trying to call width() on RenderText objects. When I called it directly on firstChild() and lastChild() of the RenderRubyRun, it works, but returns the frame width, which isn't useful for my purposes. Instead I called maxPrefWidth() which has the values I'm after. (only, I guess, if the ruby text and ruby base is a single line…) > dave > (hy...@apple.com) Regards, Eric
