Subject: Functions behaving according to button presses
Date: Mon, 28 Aug 2023 18:11:04 +0000 [thread overview]
Message-ID: <9pPuCpfhgOsgqakOyxuaK6ysqw46y4PFCrxJ2UbbDa1A7RAOgrJr7oavohUYjsYh0SQzkKsdR7j_jbbBVY4aKps2aLUMsaXS1yG3uzbkeoU=@protonmail.com> (raw)
Have noticed that I can have a function like this, which I can
use with elisp code, using for example
(insert-button "[Next]" 'action 'action-snapshot 'follow-link t)
The above will also work with any button property name like "[Next]".
Alternatively I can execute only the "[B5]" part using
(insert-button "[B5]" 'action 'action-snapshot 'follow-link t)
Or call it interactively with 'M-x action-snapshot'. In such case,
the function would execute '(insert "that")'.
(defun action-snapshot (&optional button)
(pcase (button-label button)
("[B5]"
(insert "this"))
(_
(insert "that"))))
Is the aforementioned description correct. Is there anything else, alternative
ways of using function that react according to button clicks ?
