I just wanted to mention that I have the same problem. Running CVS
Emacs as of 2007-01-1 under Mandriva GNU/Linux, using GNOME with its
Metacity window manager. What I do is this:

 $ emacsclient -e "(my-function)"

and my-function is:

(defun my-function ()
 (select-frame-set-input-focus (selected-frame)))

(well, of course it does more than that but...)

Up until today I haven't played with emacsclient under GNU/Linux. I
have just used gnuclient & friends under w32. I am currently coding a
small command/url/hatever launcher in Emacs, and the current behavior
is quite frustrating (when Emacs is not the topmost window).

I see this code in xterm.c:

XTframe_raise_lower (f, raise_flag)
     FRAME_PTR f;
     int raise_flag;
{
  if (raise_flag)
    {
      /* The following code is needed for `raise-frame' to work on
         some versions of metacity; see Window Manager
         Specification/Extended Window Manager Hints at
         http://freedesktop.org/wiki/Standards_2fwm_2dspec

         However, on other versions (metacity 2.17.2-1.fc7), it
         reportedly causes hangs when resizing frames.  */

      /* Lisp_Object frame;
         const char *atom = "_NET_ACTIVE_WINDOW"; */

      x_raise_frame (f);

      /* XSETFRAME (frame, f);
         Fx_send_client_event (frame, make_number (0), frame,
                            make_unibyte_string (atom, strlen (atom)),
                            make_number (32),
                            Fcons (make_number (1),
                                   Fcons (make_number (time (NULL) * 1000),
                                   Qnil))); */
    }
  else
    x_lower_frame (f);
}

Is is that piece of code that fails? My version of metaciy is 2.16.1.

raise frame no go

[Leo]

Hi there,

I want to use emacsclient to bring Emacs frame to the front. I tried
several functions including raise-frame, x-focus-frame etc, but none
of them worked. All they do is causing the Emacs frame to flash in the
taskbar. Any ideas?

This is tested in Gnome 2.16 in Fedora 6.
Emacs 23: 20061218.

I suppose you have `server-raise-frame' set to t (the default), and
are using something like:

  emacsclient --eval "(raise-frame)"

> This is tested in Gnome 2.16 in Fedora 6.

Must be something with your window manager...

Have you tried with the CVS HEAD version (Emacs 22.0.92 right now)?

Yes.

Yes.

It is the standard default window manager metacity. How does that
raise-frame work for Emacs with GTK+?

No. But I suspect it will also happen in 22.0.92.

Thank you for your help, Juanma.
