IIRC, it's just syntactic sugar since `org-list-write-struct' will do the `copy-tree' for you in most situations (i.e., when you don't use a function that modifies structure by side-effect).

See `org-list-write-struct' docstring. Basically, STRUCT doesn't match real structure anymore since step C. You need to provide the original structure as a third argument so `org-list-write-struct' can modify buffer by set difference. (let* ((struct (org-list-struct)) (old (copy-tree struct))) (org-list-set-checkbox (line-beginning-position) struct "[X]") (org-list-write-struct struct (org-list-parents-alist struct) old)) Regards, -- Nicolas Goaziou

What am I doing > wrong? `org-list-set-checkbox' modifies the structure, i.e., the internal list representation. It doesn't modify the buffer. You would have to apply the new structure to the buffer with `org-list-write-struct'. Anyway, it's much simpler to use `org-toggle-checkbox'. Regards, -- Nicolas Goaziou
[O] API problem
To solve a problem I have the following line in an org file: - [ ] B (org-list-set-checkbox (line-beginning-position) (org-list-struct) "[X]") ITEM STRUCT CHECKBOX (org-list-send-item (line-beginning-position) 'end (org-list-struct)) ITEM DEST STRUCT Executing the org-list-send-item brings the entry to the end of the list, but executing org-list-set-checkbox does nothing. What am I doing wrong? Because looking at the API I use the right parameters. I also do not get an error message. -- Cecil Westerhof
