Subject: How to get a window Lisp_Object from struct window *w?
Date: Mon, 17 Sep 2018 17:57:45 -0700 [thread overview]
Message-ID: <m2va73hbau.wl%esq@lawlist.com> (raw)
I am chiseling away at feature requests #17684 (crosshairs) and #22873 (multiple fake cursors).
In this particular example, redisplay gives us the w (struct window *w) as it goes through each window. I am recording the window Lisp_Object in a cache (also a Lisp_Object) and am later checking that cache to see if w == XWINDOW (window). There is no guarantee that the window that I am interested in is the selected_window, and the functions giving me the w do not provide the window as an incoming argument. I see that I can use:
Lisp_Object window = window_from_coordinates (f, opoint_x, opoint_y, &part, true);
get-buffer-window/w->contents is not helpful because there may be more than one window on the frame displaying the same buffer.
I was wondering if there is a more efficient way to derive window from a struct window *w?
Thanks,
Keith
