Dedicated *Completions* frame iconified but not de-iconified

Dedicated *Completions* frame iconified but not de-iconified

[Reiner Steib]

Hi,

I recently started to show the *Completions* buffer in a dedicated
frame:

(setq same-window-buffer-names
      (remove "*Completions*" same-window-buffer-names))
(add-to-list 'special-display-buffer-names
	     '("*Completions*" ((height . 20))))

After clicking on an alternative with the mouse iconifies the
completions frame[1].  But the next time a completions buffer is
generated, the completions frame is not de-iconified.  I think the
frame should be made visible.

I tried to put `make-frame-visible' in `completion-setup-hook' without
success and I didn't find the right place in `simple.el'.  Can anyone
point me to the right direction?

Bye, Reiner.

I don't claim this is the way to go for everyone, but you might want to look
at how I deal with this in my library `oneonone.el'. I've long had a
dedicated *Completions* frame, and there are a few twists and turns you
might want to keep in mind. Anyway, in case it helps:

Library: http://www.emacswiki.org/cgi-bin/emacs/oneonone.el.
Explanation:
http://www.emacswiki.org/cgi-bin/wiki/Help_and_Completions_Frames.

See, in particular, function 1on1-display-*Completions*-frame - it should
help with your problem.

Hmm... odd.  I've used a dedicated frame "for ever" and it pops right back
up for me.  And I can't seem to find any place in my .emacs where
I workaround such a problem either.

Hm, it might depend on the window manager.  I use fluxbox:

$ fluxbox -version
Fluxbox 0.9.14 : (c) 2001-2005 Henrik Kinnunen

When I try with plain twm, fvwm1 or blackbox, the frame is
de-iconified.  So it's probably a bug in fluxbox.

Could you point me to the relevant code in Emacs responsible for
de-iconifying the frame so that I can report to the fluxbox people?
Thanks.

Bye, Reiner.

Or could you help me to provide a simple recipe?  *time passes* Okay,
here one...

--8<---------------cut here---------------start------------->8---
(switch-to-buffer "*Messages*")
(setq sit 3)
(defun sleep (seconds)
  (sit-for seconds)
  (sleep-for seconds))
(sleep sit)
(message "Creating frame FLUXBOX-DEBUG...")
(setq f (make-frame '((name . "FLUXBOX-DEBUG") (height . 10))))
(message "Creating frame FLUXBOX-DEBUG...done")
(sleep sit)
(message "Iconifying frame FLUXBOX-DEBUG...")
(iconify-frame f)
(message "Iconifying frame FLUXBOX-DEBUG...done")
(sleep sit)
(message "Trying to make frame FLUXBOX-DEBUG visible...")
(make-frame-visible f)
(message "Trying to make frame FLUXBOX-DEBUG visible...done")
(sleep sit)
(message "If FLUXBOX-DEBUG frame is not visible (still iconified), there's a bug.")
--8<---------------cut here---------------end--------------->8---

I've sent it to the fluxbox list.

Bye, Reiner.

The code in temp_output_buffer_show includes this:

  if (!EQ (Vtemp_buffer_show_function, Qnil))
    call1 (Vtemp_buffer_show_function, buf);
  else
    {
      window = Fdisplay_buffer (buf, Qnil, Qnil);

      if (!EQ (XWINDOW (window)->frame, selected_frame))
	Fmake_frame_visible (WINDOW_FRAME (XWINDOW (window)));

Apparently that call to Fmake_frame_visible is not doing the job for
you.  Can you determine why not?

I presume it is the code in x_make_frame_visible (xterm.c).

You could try first running under GDB and making sure that that
function really is being called.  It's possible that some strangeness
prevents Emacs from calling it.
