C-x 3 (split-window-horizontally) & C-x 1 (delete-other-windows)

C-x 3 (split-window-horizontally) & C-x 1 (delete-other-windows)

[Sam Steingold]

GNU Emacs 23.0.60.4 (x86_64-unknown-linux-gnu, GTK+ Version 2.8.20)
 of 2008-05-05 on nyc-qws-005
 '--with-x-toolkit=gtk' '--prefix=/mnt/office/dev/opt'

When I split the emacs window horizontally and maximize the frame (X
window), I get two 80-char-wide buffers + wide menu bar which can
accommodate even the dired menus, which is very convenient.
I see 2 issues with this arrangement:

1. even though I can imagine that I might want to have one 160-char-wide
   window every once in a while, by far the more common situation would
   be wanting to preserve 2 columns.  Thus I would want C-x 1 to delete
   all other windows in the current column and leave the other column
   intact (as if the other column were a separate frame glued to this
   one side by side)

2. it would be nice to be able to drag the separator between the columns
   with the mouse to resize the windows, much like it is done with the
   vertically split windows (one can drag the mode line).

Yes, that's my preference, too.  I've bound the function
`th-delete-other-windows' to `C-x 1' to get that behavior.

(require 'windmove)

  (interactive)
  (let ((win (selected-window)))
    (save-excursion
      (while (condition-case nil (windmove-up) (error nil))
        (delete-window)
        (select-window win))
      (while (condition-case nil (windmove-down) (error nil))
        (delete-window)
        (select-window win)))))

        (select-window win)))))

(defun th-delete-other-windows (&optional arg)
  "If ARG is 1 (no prefix arg given) or 2 delete all windows

A bit hackish, but works.

Well, here that's possible.  The mouse pointer turns to <-> on the right
fringe of the left window.

The proposal to add a notion of `group' of windows (via a `group'
window property) would do exactly what you want, AFAICT, although it's
currently designed with the intention to mimick some IDEs and to provide
features similar to what ECB needs.

I'm currently considering an option called max-window-height|width.
Suggestions welcome.

I don't see this.
what package enables this behavior?

thanks.

You don't need an extra package, but it seems you have to disable
scroll-bar-mode.  (IMO that's a bug, isn't it?)

But even with scroll-bar-mode you can resize the windows by dragging at
the position where both mode-lines meet.

If you use fringes you can try the attached functions.  I once tried to
detect lateral down-mouse-1's on the scroll-bar but gave up soon.  IMHO
Emacs should provide both vertical and horizontal dividers, at least
optionally.  Hence I agree, it's a bug, and - patches welcome.

Please don't.  I find it a complete abomination that MS Windows'
scrollbars snap back if you accidentally skid off sideways while
dragging (dragging exactly vertically is rather hard).

Having this operation resize the windows would be even worse.  I don't
want to be forced into having to steady my hand horizontally when doing
a vertical operation.

The annoyance possibly would be less if the larger of the drag offsets
(X or Y) would win out, but that means that the drag mode might jump
from one to the other with a somewhat jarring effect.

That was my conclusion, indeed.

I envisioned some sort of "dead angle" where dragging didn't have any
effect.  But the transition would have to be done in some smooth way and
I didn't see any great benefits in this so I gave up.

It's not a bug so much as a limitation in some toolkit scrollbars.
