Message-ID: <m2y3ax3nn7.wl%esq@lawlist.com> (raw)
Thank you, Eli, for looking at this particular thread.
The x coordinate sought will be used as the 3rd argument to draw_window_cursor in conjunction with feature requests 17684 (crosshairs) and 22873 (multiple fake cursors).
The method of calculation used in the initial post is off by a few pixels when dealing with each of the fact patterns described. Here is a sample _current_ line (miscellaneous characters of varying pixel widths) where my calculations go awry:
("Google の click-tracking コードをリンクの url から取り除きます") ("Google 検索結果のテーブルを縦方向で揃えて幅を狭めます") ("すべてのページに w3m が扱える name アンカーを追加します") ("http://*.hp.infoseek.co.jp/* で広告を取り除きます") ("http://linux.ascii24.com/linux/* で広告を取り除きます") ("ミクシィ用フィルタ") ("朝日新聞用フィルタ") ("すべてのページでインラインフレームを取り除きます")
