How to prevent window split in a single frame

Question

I'm in emacs 24.something on a Windows platform. I have an agenda generated by org that I would like to keep on continuous display. I use multiple frames, and multiple windows per frame, for my other work. What I would like is a single frame with a dedicated window displaying my agenda buffer that is NOT split

(set-window-dedicated (selected-window) t)

seems to help, but doesn't quite do the trick.

Any ideas?

The following link contains a detailed example of how to display a particular buffer in a particular frame, which includes making it the only window in the frame -- it also includes solutions for non-file-visiting buffers (like `*Org Agenda*`) and file-visiting buffers: http://stackoverflow.com/a/18371427/2112489 Unfortunately, it is a little complex and may take some time to digest and incorporate into your workflow. I'm sorry that I don't have a simple solution. — lawlist, Feb 11 '15 at 20:32

A similar question was asked here. Try this solution:

(with-current-buffer
  ;; initialize org-agenda here
  ;; this sexp MUST return a buffer,
  ;; to be used by with-current-buffer
  (blah blah initialize org-agenda blah blah)
  (make-frame '((unsplittable . t)))
  (set-window-dedicated-p
    (get-buffer-window (current-buffer) t) t))

Disclaimer: I, personally, don't use org-agenda, so I can't guarantee that this will work. It should if org-agenda behaves nicely.

You should warn the reader that the first argument of with-current-buffer has to be the agenda buffer. – Malabarba Feb 13 '15 at 01:38
Indeed. Edited to reflect that. – PythonNut Feb 13 '15 at 02:22

There was only one thing wrong with the code you tried, in terms of making the window dedicated:

(set-window-dedicated (selected-window) t)

The function is set-window-dedicated-p, not set-window-dedicated. Try again, without the typo:

 (set-window-dedicated-p (selected-window) t)

That will prevent both you and Emacs from using the window for another buffer. For example, C-x b will raise an error.

To prevent automatic splitting of the window, you can do this:

 (set-frame-parameter nil 'unsplittable t)

That will not prevent you from splitting the window, e.g. using C-x 2, but it will prevent Emacs from splitting it automatically.
