maxframe provides the ability to maximize the emacs frame and stay within the display resolution.
Example of lines to be added to your .emacs:
(require 'maxframe)
(add-hook 'window-setup-hook 'maximize-frame t)If using two framebuffers (monitors), it might be necesssary to specify a mf-max-width value set to the pixel width of main framebuffer. This is necessary because emacs does not yet support sniffing different framebuffers. Example:
(require 'maxframe)
(setq mf-max-width 1600) ;; Pixel width of main monitor.
(add-hook 'window-setup-hook 'maximize-frame t)To restore the frame to it's original dimensions, call restore-frame:
M-x restore-frame
puts the emacs frame in the top left corner of the display and calculates the maximum number of columns and rows that can fit in the display
There is a good list of full-screening alternatives on the Emacs Wiki.
While I still have maxframe in my emacs initialization, I only use it as a
backup for when ns-toggle-fullscreen is not present. I compile emacs with
native fullscreen support now, and it's pretty nice. If you use
homebrew, here's the compilation step
that'll do it for you.
$ brew install emacs --srgb --cocoaSee the relevant portion of
my emacs config
to see how to make the distinction between ns-toggle-fullscreen and
maxframe.
Requires Emacs 22 (for fringe support), but maximize-frame still works under Emacs 21 on Windows.
Emacs does not recognize when the display's resolution is changed. This is a problem because I would like to be able to re-maximize the frame after connecting to a display with different resolution. Unfortunately, display-pixel-width and display-pixel-height yield the display resolution values from when emacs was started instead of the current display values. Perhaps there's a way to have emacs re-sniff these values, but I'm not yet sure how.
The w32 specific functions were borrowed from the Emacs Manual: http://www.gnu.org/software/emacs/windows/big.html#windows-like-window-ops
