Frames: selectively enabling GUI

Frames: selectively enabling GUI

[Joel J. Adamson]

Howdy Friends,

I've discovered how cool it is to have a "work frame" on one virtual
desktop in KDE, that is a full-screen frame with no menu-bar,
scroll-bar, toolbar or frame boundary.  It looks like a console, but
with better color rendering (try it out).  NOTE: this is using KDE's
full-screen functionality, not the Emacs command-line option
--full-screen.

However, on my "home" workspace, I also keep two frames with Gnus and
my diary.  In those frames I'd like to have the menu-bar at the
least.  I've been mucking about with make-variable-frame-local, but
the problem I'm having is controlling the modes from within a function
(perhaps a hook).  I just don't know where to go from
make-variable-frame-local --- can I even make a mode frame-local?
What's the relationship between a mode and a variable?

Has anyone found a way to do this already?

Thanks,
Joel

Most of the time a variable indicates if a mode is active, but in
general setting the variable won't toggle the mode.

`M-x apropos RET scroll-bar RET' pointed me to

,----[ C-h f toggle-scroll-bar RET ]
| toggle-scroll-bar is an interactive compiled Lisp function in
| `scroll-bar.el'.
| (toggle-scroll-bar ARG)
| 
| Toggle whether or not the selected frame has vertical scroll bars.
| With arg, turn vertical scroll bars on if and only if arg is positive.
| The variable `scroll-bar-mode' controls which side the scroll bars are
| on when they are turned on; if it is nil, they go on the left.
`----

That's exactly what you're looking for. :-)

Bye,

There are frame parameters for this. See the Elisp manual and/or have a
look at the source code for `menu-bar-mode', `toggle-scroll-bar' etc.

Here's the solution:

**********************************************************************
(defun gnus-frame-defaults ()
  (mapc 'make-variable-frame-local
	 '(height width menu-bar-lines tool-bar-lines vertical-scroll-bars))
  (modify-frame-parameters '() '((height . 40)
				 (width . 136)
				 (menu-bar-lines . 1)
				 (tool-bar-lines . 1)
				 (vertical-scroll-bars . 1))))
(add-hook 'gnus-group-mode-hook 'gnus-frame-defaults)
**********************************************************************

I am writing this now in a fully-tooled, fully-scrolled and
menu-ridden frame.  My other frames are untouched.

Thanks for your help,
Joel

I use ratpoison as my window manager (keyboard driven, no window
decorations) and turned off menus, scroll bars, etc. in Emacs.

I've bound "<down-mouse-3>" to `mouse-major-mode-menu'.  In this way I
still have the major mode menu at my disposal but no menu bar taking
up valuable screen space.
