Re: [External] : programmatically make window full length but not change width

[Mickey Ferguson via Users list for the GNU Emacs text editor <help-gnu-emacs@gnu.org>]

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")))
