Full screen mode on windows

Full screen mode on windows

[Ivan Kanis]

Hello,

There is nice feature in Putty called full screen mode. It takes away
all windows decoration including the taskbar.

I would like to implement this feature natively on emacs. I have two
ideas for the api:

1) Either I make a function called w32-toggle-fullscreen and do all
the right thing in C,

2) Or I could expose the GetWindowLongPtr, SetWindowLongPtr and
SetWindowPos as lisp function and write the toggle in lisp.

Which approach is the most likely to get included?

For info here is the Putty code that does the job :

    /* Remove the window furniture. */
    style = GetWindowLongPtr(hwnd, GWL_STYLE);
    style &= ~(WS_CAPTION | WS_BORDER | WS_THICKFRAME);
    if (cfg.scrollbar_in_fullscreen)
	style |= WS_VSCROLL;
    else
	style &= ~WS_VSCROLL;
    SetWindowLongPtr(hwnd, GWL_STYLE, style);

    /* Resize ourselves to exactly cover the nearest monitor. */
	get_fullscreen_rect(&ss);
    SetWindowPos(hwnd, HWND_TOP, ss.left, ss.top,
			ss.right - ss.left,
			ss.bottom - ss.top,
			SWP_FRAMECHANGED);

Thanks for your feedbacks.

I would suggest looking at the existing fullscreen option for X:

      (set-frame-parameter nil 'fullscreen  'fullboth)

and make that work for w32, if it doesnt already!

It does work, although it only emulates the fullscreen mode.

But 

   (w32-send-sys-command #xf030)

will do exactly what the OP wants.

Maybe, but it does not do very much for me ... ;-)

Are you sure you got the figures right?

But that's what the OP wanted, isn't it?

Not sure. I thought he wanted to get rid of the title bar too. That has 
been usual for things like this before. But you are probably right.

Neither the fullscreen parameter, nor the command above produce a full 
screen window. They both produce a maximised window that still contains 
the window decorations, and does not overlap the taskbar.

I knew how to maximize with the w32-send-sys-command command. By full
screen I mean no title bar, no windows decoration and no taskbar.

Why would you want such a thing?  If you don't want any GUI features
at all, type Alt-RET into the Command Prompt window, and then invoke
"emacs -nw".  Is that what you want?

Eli> Why would you want such a thing?

I'm playing around with using this (on Linux) to do presentations in
Emacs.  My current code is based on outline mode, but I'm thinking of
switching to Muse.

I reported a full-screen bug a while ago for Linux... really it would
be nice to have both "real full screen" (for presentations) and "full
screen but not hiding the panel" (for more ordinary Emacs-based apps,
like a gud session).

Emacs without title bar, window decorations, or taskbar, is still
very different than emacs in a terminal...

Why? It looks good on Putty. It can be done on X, why not on Windows?
It maximises screen estate and hides distractions so that I can focus
on what needs to get done.

AFAIK Emacs in the command prompt will not display picture and bdf
fonts, I use both extensively.  I don't think it has mouse support
either which I use from time to time.

I have wanted a feature like this for a long time for W32.
I started a brief gnu.emacs.help thread on the question in
March [1].  At home I use stumpwm which puts all
applications in a true fullscreen mode that maximizes
available screen area while still allowing the use of GUI
tools like the mouse and nice fonts, etc.  But at work I am
stuck with W32 and can't get that effect easily.

Also, I suspect that a nice presentation package would be
fairly easy to write for Emacs and could be quite useful,
but it would be helpful for such a program to have access by
way of Emacs lisp to a true fullscreen toggle on all
platforms.  The problem is that the W32 environment does not
seem to provide a high-level or easily accessed function to
do that.  An attempt seems to have been made that requires
python[2].

There is also some interest in programs like Dark Room or
Writeroom which are text editors that are designed to be
visually minimalistic for the purpose of reducing
distractions.  (There is a page on the EmacsWiki that
describes some related hacks [3].)  Emacs is evolved for use
as a text editor for coding and some related things;
features like a totally blank screen save text (no title
bars or tool bars, etc.) seem to be of interest more to
writers of fiction and poetry, and so forth.  A related
feature that would be nice for the ``Writeroom'' editing
style, or for a presentation manager, is that of a
disappearing mode-line, similar to the ``auto-hide''
function available for the ``task-bar'' used in the Windows
GUI.  I know one attempt has been made to implement this for
Emacs[4], though it does not reclaim that space (or
minibuffer space) for editing use, which would be nice.

Hi,
 I have the following key mapping and it just works fine on M$. You
can add tests to check if tool bar is enabled and remove it, restore
it later by storing keeping track (the way I restore - max/restore).

(global-set-key [(control ?=)] '(lambda ()
				  (interactive)
				  (if (and (boundp '*frame-max) *frame-max)
				      (progn
					(setq *frame-max nil)
					(w32-send-sys-command 61728))
				    (progn
				      (setq *frame-max t)
				      (w32-send-sys-command 61488)))))

This kind of thing has been suggested, but it does not solve
the main problem (which is what the thread starter asked
about) of removing all window borders (particularly the
title bar) in the W32 environment.  I spent a couple of
hours at one point trying to find a code to use with the
'w32-send-sys-command function that would have that effect,
but to no avail.  It can be done, of course, by some means;
Internet Explorer 7 (as an example) responds to the Windows
standard F11 key the way that is being described (it even
has a nice feature that allows you to temporarily get out of
the fullscreen mode by bumping the top of the screen with
the mouse pointer).
