It appears that one cannot define clickable text in org-mode. I was
trying to make some text in an org-file respond to different types of
clicking. I know that links provide some functionality for this, but
out of curiosity I wanted to see what else I could do.
If I run the following code on a buffer in text-mode, the first four
characters in the buffer turn blue with a white background, they turn
a light green when the mouse is over them, and finally a message box
pops up when I click on the characters.
(let ((map (make-sparse-keymap)))
(define-key map (kbd down-mouse-1)
'(lambda() (interactive) (message-box it works!)))
(add-text-properties 1 5 `(keymap, map
font-lock-face (:foreground blue
:background white)
mouse-face highlight)))
If I switch to org-mode, the clickability and mouse highlighting go
away. They also do not appear when I run the function in an
org-buffer.
Does anyone know if there is a feature in org-mode that turns this
off, or if there is a way to get the clickability to work? Is it
related to having links that are clickable?
I'm not sure to understand your use case -- why do you want clickable text in
the first place (other than links)?
But, did you look at `org-add-link-type' which does allow some kind of
powerful stuff (mainly for export, but can maybe be diverted from its
original
purpose)?
I guess you also are aware of the elisp and shell links you can already put
in
any Org file, as clickable buttons?
I was just learning about programming interactive features into emacs
buffers, and something that worked in one major mode did not work in
org-mode. I have narrowed it down to an effect of font-lock-mode. When that
is off, the mouse-clicking works fine, when it is on, the font syntax
highlighting works fine, but not the clicking in org-mode.
In terms of usage, I could see this as a way to automatically make links
out of different words, or in a related application to overlay tooltips on
specific words without having to markup the org-file. In essence, moving
some markup to a lisp file that is run before opening the org-file.
I am familiar with `org-add-link-type' and have used that to do some pretty
cool things, as well as the elisp and shell links. With the clickable text
code I described, you can actually do different things with different mouse
clicks, including different mouse buttons, and presumably on mouse button up
events. It is not obvious that can be done with `org-add-link-type'; you get
the same behavior with any mouse button click. I havent advanced to a point
where I could get emacs-lisp to tell me which mouse event occurred on
clicking on a link. That seems possible though.
Thanks for giving more information about what you're looking for.
However, I must admit having no experience in that. Sorry. But, if I had to
try and understand why your above code does not work, I would first give a
deep look at some agenda commands: I know they *do* use text properties (for
handling the clicks on the agenda line, in particular). These could help you
achieving your goal, maybe?
Best regards,
Seb
