How to dynamically change org-clock-mode-line-total?

[Marcin Borkowski]

Hi all,

I want to be able to dynamically switch between various settings of
org-clock-mode-line-total.  To this end, I wrote the following code.

--8<---------------cut here---------------start------------->8---
(setq org-clock-mode-line-total-settings
      '((current . "time spent in this chunk on the current task")
	(today . "time spent today on the current task")
	(all . "total time spent on the current task")))
(setq org-clock-mode-line-total-setting-number 0)

(defun toggle-org-clock-mode-line-total-setting (setting-number)
  "Toggle between org-clock-mode-line-total settings.
With a numeric argument, use setting SETTING-NUMBER."
  (interactive "P")
  (if (numberp setting-number)
      (setq org-clock-mode-line-total-setting-number
	    (mod setting-number (length org-clock-mode-line-total-settings)))
    (setq org-clock-mode-line-total-setting-number
	  (mod (1+ org-clock-mode-line-total-setting-number)
	       (length org-clock-mode-line-total-settings))))
  (let ((org-clock-mode-line-total-setting (nth org-clock-mode-line-total-setting-number
						org-clock-mode-line-total-settings)))
    (setq org-clock-mode-line-total (car org-clock-mode-line-total-setting))
    (org-clock-update-mode-line)
    (message "Modeline shows %s."
	     (cdr org-clock-mode-line-total-setting))))
--8<---------------cut here---------------end--------------->8---

Unfortunately, it doesn't work.  I checked that the variable
org-clock-mode-line-total is modified correctly, but even after saying
(org-clock-update-mode-line), nothing gets updated.  Am I doing
something wrong?

TIA,

AFAICT, org-clock-mode-line-total is not used by
org-clock-update-mode-line at all.  It may be that the name of the
variable is misleading. The only place I see it used is
org-clock-get-sum-start.

Thanks, that helped!  It seems my function is now working (almost)
correctly, although it is now cargo cult programming - I don't really
understand what's going on here.  I'll try to make sense of it tomorrow,
now it's too late;-).

Best,
