;;; Commentary:
;;
;;    Frame configuration that uses one frame per window.
;;
;;  This library is part of One-on-One Emacs, a collection of
;;  libraries that try to make Emacs more frame-oriented and less
;;  window-oriented.
;;
;;  This library sets up Emacs to use multiple frames: individual
;;  frames are used, by default, instead of Emacs windows.  That is,
;;  the default is to use a frame for each Emacs window: one window on
;;  one frame.
;;
;;  You can configure each of the frames defined here.
;;
;;  Default properties are defined here for normal frames and
;;  "special" frames, which show "special-display buffers" (see Emacs
;;  manual for info on such frames).
;;
;;  In addition, these user options control the creation of three
;;  separate, specialized frames:
;;
;;    - `1on1-minibuffer-frame-flag' - minibuffer frame
;;    - `1on1-*Help*-frame-flag' - *Help* buffer frame
;;    - `1on1-*Completions*-frame-flag' - *Completions* buffer frame
;;
;;  More precisely, buffers *Help* and *Completions* are always
;;  created in frames that have the special properties defined here.
;;
;;  `1on1-minibuffer-frame' is a standalone minibuffer frame.  It is
;;  the only frame to have a minibuffer.  By default, it is
;;  automatically sized to the full width of your display and placed
;;  at the bottom of the display.  To help you perceive changes to
;;  different minibuffer recursion levels, the background color of
;;  this frame is changed slightly with each recursion-depth change.
;;
;;  This library is especially useful if used in combination with
;;  One-on-One Emacs libraries `autofit-frame.el', which automatically
;;  fits frames to their sole window, and `fit-frame.el', which lets
;;  you fit a frame to its selected window manually.  Library
;;  `autofit-frame.el' uses library `fit-frame.el'.
;;
;;  Because Emacs is not really designed to be frame-oriented, there
;;  are many built-in and standard functions that produce
;;  less-than-optimal results when frames, instead of windows, are the
;;  default.  In other One-on-One Emacs libraries, I have fixed most
;;  of these built-in functions to play well with frames.
;;
;;  For more information on One-on-One Emacs see
;;  http://www.emacswiki.org/cgi-bin/wiki/OneOnOneEmacs.
;;
;;  To use this library, put the following at the *END* of your init
;;  file, `.emacs' (or `_emacs').  In particular, if your init file
;;  contains a `custom-set-variables' expression, then the following
;;  must appear *AFTER* that expression, in order for this to take
;;  into account your customizations of any `1on1-' user options.
;;
;;    (require 'oneonone)
;;    (1on1-emacs)
;;
;;  Initial frame: By default, the initial Emacs frame is like all
;;  other normal (non-special-display) frames; that is,
;;  `initial-frame-alist' effectively uses the frame properties
;;  defined in `default-frame-alist'.  If you would like the initial
;;  frame to be different, set `default-frame-alist' to nil after
;;  requiring `oneonone.el' but before executing `1on1-emacs':
;;
;;    (require 'oneonone)
;;    (setq default-frame-alist nil)
;;    (setq initial-frame-alist '((background-color . "White"))); e.g.
;;    (1on1-emacs)
;;
;;  If you want the text cursor to change to a box when Emacs is idle,
;;  then add this line also to your init file:
;;
;;    (toggle-box-cursor-when-idle 1) ; Turn on box cursor when idle.
;;
;;  Info and Customize frames: I recommend that you put the following
;;  code in your init file, so that Info and Customize buffers will
;;  display in their own frames.  Which code to use depends on your
;;  version of GNU Emacs.
;;
;;    ;; Change first test to (string-match "22." emacs-version)
;;    ;;   after 22.x release.
;;
;;    (cond ((or (string-match "22." emacs-version)
;;           (string-match "21.3.50" emacs-version))
;;           (remove-hook 'same-window-regexps "\\*info\\*\\(\\|<[0-9]+>\\)")
;;           (remove-hook 'same-window-regexps "\\`\\*Customiz.*\\*\\'"))
;;          ((< emacs-major-version 21)
;;           (remove-hook 'same-window-buffer-names "*info*"))
;;          (t  ;; E.g. Emacs 21.3.1
;;           (remove-hook 'same-window-buffer-names "*info*")
;;           (remove-hook 'same-window-regexps "\\`\\*Customiz.*\\*\\'")))
;;
;;  If you use MS Windows, you might also want to add this, to avoid
;;  giving focus to a frame just because it is raised:
;;
;;    (setq w32-grab-focus-on-raise      nil
;;          win32-grab-focus-on-raise    nil) ; older name
;;
;;  To get an idea what this library does, without modifying your init
;;  file, you can just load it and then use `M-x 1on1-emacs'.
;;
;;  Notes on user options defined here:
;;  ---------------------------------
;;
;;  Some user options are used here only as conveniences to define
;;  frame-parameter alists.  They are defined using `defvar', not
;;  `defcustom', because you cannot use Customize to define them
;;  independently of the alist user options they help to define.
;;  The alists themselves are the variables to customize.  If you
;;  want to change the `defvar' variables individually and then use
;;  them to set the alist variables, then use `set-variable' or
;;  `setq', not Customize, to change them, and restart Emacs for
;;  their changes to take effect.
;;
;;  Changes to any user options defined here with `defcustom' will
;;  take effect as soon as `1on1-emacs' is executed, so you can do
;;  `M-x 1on1-emacs' to see their changes (no need to restart
;;  Emacs).
;;
;;  User options `1on1-color-minibuffer-frame-on-setup-increment' and
;;  `1on1-color-minibuffer-frame-on-exit-increment' determine how much
;;  to change the color of the minibuffer frame when the minibuffer is
;;  entered and exitted.  They are hue increments, and should be
;;  opposite in sign.  They should cancel each other out, so that the
;;  color returns to what it was initially at any given
;;  recursive-minibuffer depth.  However, because of the way HSV and
;;  RGB color-component conversion works, the best cancellation does
;;  not occur when these have the same absolute value.  And, how much
;;  their absolute values should differ depends on that magnitude.
;;  It's best to just set one of these to an increment you like, and
;;  then fiddle with the other until they more or less cancel.

;; 2005/01/19 dadams
;;     Use defcustom now.
;;     Removed (put ... 'variable-interactive...).
;;     1on1-minibuffer-frame-top/bottom: Must be an integer (for set-frame-position).
;; 2004/12/18 dadams
;;     Bind after-make-frame-functions to nil when create 1on1-minibuffer-frame.
;; 2004/11/26 dadams
;;     Removed ;;;###autoload's.

;;     added 1on1-set-minibuffer-frame-top/bottom.
;; 2001/01/05 dadams
;;     1. 1on1-minibuffer-frame-width: Use 1on1-minibuffer-frame arg for frame-char-width.
;;     2. Don't define width when initially set 1on1-minibuffer-frame-alist.  Instead,
;;        use set-frame-width afterward, so 1on1-minibuffer-frame-width uses correct
;;        character size.
;; 2001/01/05 dadams
;;     1. These vars no longer user options (interactively changeable):
;;        1on1-completions-frame-background, 1on1-completions-frame-mouse+cursor-color,
;;        1on1-help-frame-background, 1on1-help-frame-mouse+cursor-color,

;;     3. Changed var 1on1-minibuffer-frame-width to nil default (now use *-percent).
;; 2000/09/27 dadams
;;     1. Added: 1on1-display-*Completions*-frame, 1on1-display-*Help*-frame.
;;     2. *Help* & *Completions* frames not created here.  Instead, use
;;        special-display-buffer-names & display-*-frame fns to define them.
;;     3. Added: top-level, abort-recursive-edit.
;; 1999/08/24 dadams
;;     1. Windows: win32-grab-focus-on-raise = nil.
;;     2. 1on1-default-frame-font different if Windows.
;;     3. Added: 1on1-separate-minibuffer-frame-flag, 1on1-menu-bar-lines,
;;        1on1-upper-left-frame-corner-default, 1on1-default-frame-size,
;;        1on1-upper-left-special-display-frame-corner-default,
;;        1on1-default-special-display-frame-size, 1on1-default-special-frame-foreground,
;;        1on1-default-special-frame-background, 1on1-default-special-frame-font,
;;        1on1-default-special-frame-mouse-color, 1on1-default-special-frame-cursor-color.
