Maximize Emacs on start up? (not the fullscreen)

Question

It\'s common for me to press alt-f10 (in GNU/Linux) after Emacs start up for maximizing window (in the Emacs terminology, it\'s actually a frame). Most of the time I press t

Answer 1

OSX:

The developer build of Emacs Trunk has a function called toggle-frame-maximized, which is included within .../lisp/frame.el. That function can be added to the after-init-hook or emacs-startup-hook, or simply included in the .emacs file that gets loaded on startup. On OSX, it increases both width and height in one-fell-swoop.

Windows XP:

The following command can be used after a make-frame command, or after Emacs generates the initial frame.

(w32-send-sys-command 61488)

OSX and Windows

Here is an example for setting the initial frame size and location -- I have it near the beginning of my .emacs file:

(let ((frame (selected-frame)))
  (cond
    ((eq system-type 'darwin)
      (setq ns-auto-hide-menu-bar t)
      (set-frame-position frame 0 0) ;; must come after `ns-auto-hide-menu-bar`
      (cond
        ((and
            (= 1920 (display-pixel-width))
            (= 1080 (display-pixel-height)))
          (set-frame-size frame 1895 1054 t))
        ((and
            (= 1920 (display-pixel-width))
            (= 1200 (display-pixel-height)))
          (set-frame-size frame 1895 1174 t))
        ((and
            (= 1280 (display-pixel-width))
            (= 800 (display-pixel-height)))
          (set-frame-size frame 1265 774 t))) )
    ((and
        (eq system-type 'windows-nt)
        (equal (w32-version) '(5 1 2600)))
      ;; (w32-send-sys-command #xf030)
      (set-frame-position frame 0 0)
      (cond
        ((and
            (= 1920 (display-pixel-width))
            (= 1003 (display-pixel-height)))
          (set-frame-size frame 1898 924 t))
        ((and
            (= 1920 (display-pixel-width))
            (= 1123 (display-pixel-height)))
          (set-frame-size frame 1876 1052 t))
        ((and
            (= 1280 (display-pixel-width))
            (= 723 (display-pixel-height)))
          (set-frame-size frame 1250 670 t))))
      ((and
          (eq system-type 'windows-nt)
          (equal (w32-version) '(6 1 7601)))
        (set-frame-position frame 0 0)
        (cond
          ((and
              (= 1920 (display-pixel-width))
              (= 1080 (display-pixel-height)))
            (set-frame-size frame 1890 1003 t))
          (t
            (message "Not yet contemplated.")))) ))

Here is an example of what I use to create new frames -- controling the exact size and location:

(defun lawlist-make-frame (&optional alist)
  (let ((frame (make-frame alist)))
    (set-frame-position frame 0 0)
    (cond
      ((eq system-type 'darwin)
        (cond
          ((and
              (= 1920 (display-pixel-width))
              (= 1080 (display-pixel-height)))
            (set-frame-size frame 1895 1054 t))
          ((and
              (= 1920 (display-pixel-width))
              (= 1200 (display-pixel-height)))
            (set-frame-size frame 1895 1174 t))
          ((and
              (= 1280 (display-pixel-width))
              (= 800 (display-pixel-height)))
            (set-frame-size frame 1265 774 t))))
      ((and
          (eq system-type 'windows-nt)
          (equal (w32-version) '(5 1 2600)))
        (select-frame frame)
        (cond
          ((and
              (= 1920 (display-pixel-width))
              (= 1003 (display-pixel-height)))
            (set-frame-size frame 1898 924 t))
          ((and
              (= 1920 (display-pixel-width))
              (= 1123 (display-pixel-height)))
            (set-frame-size frame 1876 1052 t))
          ((and
              (= 1280 (display-pixel-width))
              (= 723 (display-pixel-height)))
            (set-frame-size frame 1250 670 t))))
      ((and
          (eq system-type 'windows-nt)
          (equal (w32-version) '(6 1 7601)))
        (select-frame frame)
        (cond
          ((and
              (= 1920 (display-pixel-width))
              (= 1080 (display-pixel-height)))
            (set-frame-size frame 1890 1003 t))
          (t
            (message "Not yet contemplated.")))) )))
