Subject: 24.3; set-frame-width didn't work in daemon mode
Date: Sun, 24 Mar 2013 20:58:45 +0800

I have the following lines in my .emacs file.

(defun my:set-frame-size (&optional frame)
  (interactive)
  (if frame
    (select-frame frame))
  (if (display-graphic-p)
      (progn
    (tool-bar-mode -1)
    ;; use 120 char wide window for largeish displays
    ;; and smaller 80 column windows for smaller displays
    ;; pick whatever numbers make sense for you
    (if (> (x-display-pixel-width) 1280)
        (set-frame-width (selected-frame) 120)
      (set-frame-width (selected-frame) 80))
    ;; for the height, subtract a couple hundred pixels
    ;; from the screen height (for panels, menubars and
    ;; whatnot), then divide by the height of a char to
    ;; get the height we want
    (set-frame-height (selected-frame)
              (/ (- (x-display-pixel-height) 200)
                 (frame-char-height)))
    )))

(add-hook 'after-make-frame-functions 'my:set-frame-size frame)

However, if i invoke a normal emacs, and create a new frame, both
set-frame-width and set-frame-height work well.

But if i invoke emacs from 'emacsclient -c -a ""', set-frame-width
didn't work. Width should be 120 instead of staying 80. (I have
"server-start in the end of my .emacs")

I tried to debug it and use message to print width out. Under both
conditions, x-display-pixel-width is 1366 and (set-frame-width
(selected-frame) 120) is excuted.

I have been looking into this (and the related 14056) now.  With a more
simple scenario using

(defun my-set-frame-size (&optional frame)
  (tool-bar-mode -1)
  (set-frame-width frame 30)
  (set-frame-height frame 10))

(add-hook 'after-make-frame-functions 'my-set-frame-size)

(server-start)

in the server Emacs, I can reproduce the bug for a 24.2.92.1 native
Windows build I happen to have around here.  For that build, the client
frame indeed does not support the requested height but uses the default
initial height instead.  I cannot reproduce the bug for any later build
I have here including one of 24.5.50.1.  So I suppose that the bug has
been fixed somewhere in between these two builds and mark this bug as
done.

Very belated thanks for the report, martin
