programmatically make window full length but not change width

programmatically make window full length but not change width

[Mickey Ferguson via Users list for the GNU Emacs text editor]

I'm trying to figure out how to generate what happens when I have my emacs
window open and I double-click on the top edge of the window.  Say I'm
working in notepad.  (The horror!)  I double-click on the top edge of the
window (not the title area, but the very edge, when the mouse pointer
changes to an up/down arrow), and the window resizes to the very top and
very bottom of the desktop, while maintaining the width it had.  (This is
how it differentiates from double-clicking on the title bar of the window,
which just maximizes the window.)

Or, if there is a simple function that does this, that would be even
better.  I just want the simplest way to make my window full length -
something I could put in my .emacs or code into a function that can be
bound to a keyboard operation.

Not sure what you're asking.  And I think maybe
you mean Emacs "frame" when you say "window".

Anyway, maybe something like this is what you're
looking for:

  maximize-frame-vertically is an interactive compiled
   Lisp function in ‘frame-cmds.el’.

  (maximize-frame-vertically &optional FRAME)

  Maximize selected frame vertically.

Is this a more recent module?  I'm on 24.5.1, and there is no such
frame-cmds.el in my distribution.

If I should upgrade to a new version, how difficult is it going to be to go
from 24.5.1?  I have some customizations in my .emacs and site-init.el
files, and I remember when I tried to go to 25, some things weren't very
good, so I just stayed on 24.5.1.

I gave you the URL in the msg you replied to (above).
It's a 3rd-party library, not part of vanilla Emacs.

Thank you, Drew.  After downloading the frame-cmds.el, I also needed
frame-fns.el to allow things to compile.  One other tweak I needed, since
my windows toolbar is at the bottom of the screen, I needed to add:

(setq window-mgr-title-bar-pixel-height '175)

This made it size correctly on my laptop.  However, if I connect to my
remote desktop computer, using either VNC or Remote Desktop Connection,
then that sizing is incorrect.  It seemed to be around 60 for that
computer.  Oh, and each of these computers have a 1920x1080 display
setting, if that makes any difference.

Is this a setting that needs to be set individually for each computer?  If
so, that's getting outside of what I would know how to do, since my goal is
to have a single .emacs file for all of the computers where I work.  Maybe
it would be a registry setting or environment variable, for which I could
easily have each computer have its own customized setting, and then the
.emacs would get that env var or reg value on startup?

I do appreciate the timely and quality help you provide.

For each context where the title bar has a different height.

`C-h v window-mgr-title-bar-pixel-height':

  Height of frame title bar provided by the window manager, in pixels.
  You might alternatively call this constant the title-bar "width" or
  "thickness".  There is no way for Emacs to determine this, so you
  must set it.

You can set it conditionally based on however you can
determine the context and the right height for it.

From the source file you see that the default value is
set using this:

(cond ((eq window-system 'mac) 22)
      ;; For older versions of macOS, 40 might be better.
      ((eq window-system 'ns)  50)
      (t  27))

If the difference between the contexts you mention is
reflected in the value of `window-system' then you can
use a similar sexp to set it appropriately in your init
file:

 (setq window-mgr-title-bar-pixel-height
       (cond ((eq window-system 'FOO) N)
             ((eq window-system 'BAR) M)
             ...
             (t 27)))

Where FOO, BAR, N, and M are whatever values you need.

See above.

For most of my computers, I can use a default value of 60, but on one of my
computers, I need 175.  So I've put this code in my .emacs file (after
loading the two frame- libraries).  On my one computer, I have an
environment variable that it reads.  This seems to do the trick!  Thanks
for the help, Drew!

(setq window-mgr-title-bar-pixel-height
  (string-to-number
    (or (getenv "emacs-window-mgr-title-bar-pixel-height") "60")))
