Screen size (pixels or whatever)

Screen size (pixels or whatever)

[Vasily Korytov]

Hey,

How do I get screen size in Emacs?

I don’t mean frame-width, but I mean eventually the number of lines that are possible to fit on the screen.

That is: on one machine I have 1400х1050 and I use:

(setq default-frame-alist
    '((height . 53)
      (width . 120)
      (top . 50)
      (left . 380)))

On second one I have 1280x768 and I use:

(setq default-frame-alist
    '((height . 45)
      (width . 120)
      (top . 3)
      (left . 220)))

I want to glue this in one configuration file that works on both machines.

I would like to know, if there is a function, that would give me the number of pixels on the current display or some other mean to detect, is it a large screen or not.

The answer is (display-pixel-width) and (display-pixel-height).

Found the answer just after posting.

Thanks for reading this.

I have those 85 and 32 so that ain't that many
pixels :) But I suspect that is chars an lines
(COLUMNS and LINES in da' shell).

But: What are you trying to do?

You know of course of --fullscreen in X? Which is the
only way one could use Emacs in X without going
nuts...

I've been using
  ;;; initial frame width,height,position
  (set-frame-width (selected-frame) 80)        ; #chars wide
  (set-frame-height (selected-frame) 52)       ; #lines ling
  (set-frame-position (selected-frame) 10 10 ) ; x y from upper-left
What's the diff???

As the OP explained in the original post, he wants those rules to work
conditionally, if certain screen resolution is detected.

I don't know how to do that internally in Emacs, but if one is running
under Linux, the command "xrandr | grep \*" will tell you the
resolution and frequency of the monitor. Maybe one can have Emacs
execute this and parse the info...

HTH, :-)

This gives you the full width and height, including menu bars. I think
Drew Adams has code that takes this into account in his 1on1 library
(http://www.emacswiki.org/emacs/OneOnOneEmacs), but I don't recall which
file this is in exactly.

`frame-cmds.el' might help; dunno.  (It in turn requires `frame-fns.el'.)

Right, my bad. Sorry, I overlooked that. Thanks.
