set-frame-position fails

set-frame-position fails

[Nick Patavalis]

Hi

>From a gnome-terminal, I start the EMACS editor which opens its main
frame at the position selected by the window manager.

In the scratch-buffer, and say:

  (set-frame-position (selected-frame) 100 100)^J
  (set-frame-position (selected-frame) 10 10)^J
  (set-frame-position (selected-frame) 150 10)^J

The frame always moves to the prescribed position. No problem so far.

Now I grab the emacs window with the mouse from its titlebar and move
it (by any amount, even the tiniest). Then I say again:

  (set-frame-position (selected-frame) 10 10)^J

The frame instantly moves to the prescribed position, and then
*immediately* returns to its *original place*. From then-on any
attempt to set the frame's position using "set-frame-position" fails
in the same manner (frame slings-back instantly after momentarily
moving).

The same behavior manifest in any new frame I open: Until the frame is
moved using the mouse, "set-frame-position" works as expected. After
the frame is moved using the mouse, "set-frame-position" no longer
works: The frame, instead, slings-back to its original location, after
momentarily changing position

I'm using:

  A Debian GNU/Linux i686-based system.

  GNU Emacs 21.4.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
  of 2005-03-17 on trouble, modified by Debian

  metacity 2.8.8

Tanks in advance for any help with this, and many thanks for making
the best editor in the world available to us.

Does the problem persist if you do
(modify-frame-parameters (selected-frame) '((user-position . t)))

The current development Emacs (from the savannah.gnu.org CVS),
compiled with GTK toolkit support *does not* have the same problem;
"set-frame-position" works as expected, even after manually moving the
frames.

The same version (CVS Emacs), compiled with LUCID toolkit support,
*still has the same problem*: After manually moving a frame,
"set-frame-position" stops working.

What does (frame-parameter (selected-frame) 'user-position)
return, before and after manually moving the frame?

Someone suggested that this is not really a bug, just the normal
behavior of the :user-position frame parameter.

Even when I set the "user-position" frame parameter, I still cannot
move the frame, and have it "stay" at the new position. All the
following fail in the same manner:

  (modify-frame-parameters (selected-frame)
                           '((top . 10)
                             (left . 100)
                             (user-position . t)))

  (modify-frame-parameters (selected-frame)
                           '((top . 10)
                             (left . 100)
                             (user-position . nil)))

  (set-frame-position (selected-frame) 10 100)

Shouldn't one of them work?

Yes, something here must be a bug.
