Subject: Adding a tooltip to text that matches a regexp?
Date: Thu, 20 Nov 2014 19:29:07 +0100 [thread overview]
Message-ID: <cd6q7kFt28iU1@mid.individual.net> (raw)
I would like to add a tooltip to any text that matches a regexp. The
buffer content is going to change, thus I can't do it once for all.
Since such text is going to be highlighted by Font Lock, it seems that
adding the tooltip in `font-lock-add-keywords` could be a solution. I
know that I must set the `help-echo` property of the matching text, like
this:
(set-text-properties (match-beginning 0) (match-end 0)
'(help-echo "Tooltip text"
font-lock-face 'my-custom-face))
Can I do this in `font-lock-add-keywords`? If so, how? If not, are
there alternative solutions?
Thank you.
