Maximizing an Emacs frame to just one monitor with elisp?

I quickly scanned the reference that you provided to maxframe. El and I don't think that you're using the same technique that I use. Does the following code snippet help you?(defun toggle-fullscreen () "toggles whether the currently selected frame consumes the entire display or is decorated with a window border" (interactive) (let ((f (selected-frame))) (modify-frame-parameters f `((fullscreen .

,(if (eq nil (frame-parameter f 'fullscreen)) 'fullboth nil)))))).

Cool! You're right, it's a completely different solution, but much better, because it gets rid of the dock and menu bar as well. Unfortunately, it only works on the big monitor of my dual-head setup, but I think the pros outweigh the cons in this case.

Thanks! – Chopmo Sep 21 '08 at 18:48 Unfortunately this doesn't seem to work with emacsformacosx. Com - any known workaround for the 'ns' window system?

– Glyph Oct 14 '09 at 15:37 This does work for the mac window system, thankfully, and I was able to use it to replace ediff-toggle-wide-display: gist.github. Com/1283061 – Nicholas Riley Oct 13 at 0:54.

Its documentation: "*The maximum display width to support. This helps better support the true nature of display-pixel-width. Since multiple monitors will result in a very large display pixel width, this value is used to set the stop point for maximizing the frame.

This could also be used to set a fixed frame size without going over the display dimensions.

Thanks for your answer, see updated description. – Chopmo Sep 18 '08 at 15:17.

This sort of thing is the job of your window manager, not the job of emacs. (For example, Xmonad handles full-screen emacs just fine. ).

Agree.. but at startup time Emacs doesn't seem to understand the window dimensions XMonad gives him. So I end up switching between some layouts to let Emacs understand its dimensions. – Rene Saarsoo Mar 2 '10 at 18:55.

I use maxframe. El to maximize my Emacs frames. It works great on all three major platforms, except on my dual-head Mac setup (Macbook Pro 15-inch laptop with 23-inch monitor).

When maximizing an Emacs frame, the frame expands to fill the width of both monitors and the height of the larger monitor. Obviously, I would like the frame to maximize to fill only the monitor it's on. How can I detect the resolutions of the two individual monitors using elisp?

EDIT: As Denis points out, setting mf-max-width is a reasonable workaround. But (as I should have mentioned) I was hoping for a solution that works on both monitors and with any resolution. Maybe something OSX-specific in the style of the Windows-specific w32-send-sys-command.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
