Opening a frame on a second monitor

[Bruce Knoth]

I've been searching for a command that allows me to open a frame on a
second monitor on WinXP. I recall that I even succeeded once, but don't
know what I did (or if I was dreaming).

I want a "make-frame-on-display" command that works on Win32 (the
existing "make-frame-on-display" command seems to only support X).

Suggestions?

Thanks,

Bruce

That's not what make-frame-on-display does.  It opens a frame on a
different X display (ie, a different login session).  Multiple monitors
in the same session are handled by setting the x and y offset in
frame-parameters to position the frame where you want it, whether on X
or on Windows.

Thanks - you answered my question. The following frame alist opens a
frame on my second monitor when used with the make-frame function.

(setq second-frame-alist
               '((top . 0)
                 (left . -1280)
                 (width . 150)
                 (height . 56)
                 (cursor-color . "deep sky blue")
                 (background-color . "Wheat")
                 (foreground-color . "blue3")
                )
              )

I appreciate your help, Jason.

FYI - You can use (x-display-pixel-width) to pick up the `1280' value
automatically, so it is correct regardless of the current display. In the case
of yours, it will be 1280.

So you could, if you wanted, use:
(setq second-frame-alist
      `((top . 0)
        (left . ,(x-display-pixel-width))
        (width . 150)
        ...

Did you mean to have the "," in front of "(x-display-pixel-width)"?
Also, the "(x-display-pixel-width)" function is in frame.el but I can't
call it without making it interactive. What's the proper way to call a
function that doesn't show up as an emacs command?

Thanks for your help,

Bruce

Yes. See the Elisp manual, node Backquote.

You can use `M-:'.

M-: (x-display-pixel-width)

Not really, as one monitor will be to the left of the other, and the
other will to be to the right of the first.  You can't generalize - some
people will configure their main monitor to the left, others to the
right, and still others will configure them above, below or even
diagonally.  The values for left and top need to be customized for the
particular setup that the user has.
