Subject: Refresh display after changing variable
Date: Mon, 2 Aug 2021 12:49:41 -0400 [thread overview]
Message-ID: <se97n5$1343$1@ciao.gmane.io> (raw)
I have this to toggle a variable:
(defun kg-toggle-whitespace-line-column ()
"Toggle whitespace line column between 80 and 101"
(interactive)
(setq whitespace-line-column (if (= whitespace-line-column 80) 101 80))
(font-lock-fontify-buffer))
(global-set-key "\C-cw" 'kg-toggle-whitespace-line-column)
However, the buffer is not refreshed with the different colors.
I also tried (refresh-display) - no success
(revert-buffer) works but seems crude.
What's the correct function?
