Default position of speedbar frame

[Stefan Boeters <st.boeters@gmail.com>]

There is an old thread ("Define geometry of speedbar window?" of 1999)
where options to define the default position of the speedbar have been
intensively discussed:

http://groups.google.de/group/gnu.emacs.help/browse_thread/thread/a8779f23992f671

However, there didn't seem to be a clear outcome. In my attempt to
position the speedbar at the left uppermost corner of the screen, I
tried the following suggested additions to the _emacs file:

A)

(setq speedbar-frame-parameters '((top . 0) (left . 0)))

B)

(require 'speedbar)
  (add-to-list 'speedbar-frame-parameters '(top . 0))
  (add-to-list 'speedbar-frame-parameters '(left . 0)

C)

(defun arc-spedbar()
  (interactive)
  (speedbar)
  (set-frame-position (selected-frame) 0 0))

None of these was successful. -- Has anyone a further hint?
