Subject: xterm-mouse-mode gives incorrect posn-object-x-y with display space
Date: Thu, 24 Nov 2022 12:22:44 -0500 [thread overview]
Message-ID: <CA354E40-9BCD-47B7-98A1-6F08E8F6B48B@gmail.com> (raw)
The mouse-down events delivered by xterm-mouse-mode do not appear to handle clicks on entities with specified space display widths correctly. Try this in a graphical window, and again in the terminal, with xterm-mouse-mode enabled:
(defun my/report-mouse (ev)
(interactive "e")
(let* ((posn (event-start ev))
(rel (posn-object-x-y posn)))
(message "Got Relative Position %S" rel)))
(insert "\n\n ---- "
(propertize " "
'extend nil
'display '(space :width (48))
'keymap '(keymap (down-mouse-1 . my/report-mouse))
'font-lock-face 'underline)
" ---- ")
Mouse 1 click positions relative to the extended-width space (underlined for visibility) are reported correctly in graphical emacs, in screen pixel units. With xterm-mouse-mode, however, relative positions are always reported as (0 . 0) for me, no matter where you click. Is something wrong with my assumption that posn-object-x-y should work similarly in graphical as well as terminal emacs with xterm-mouse-mode (modulo the larger “pixel” size)?
