Horizontal Scroll bars

Horizontal Scroll bars

[Fabrizio Sidoli]

Hi,

I do hope someone can help me. I was wondering if it was possible to add a 
horizontal scroll bar to my emacs window? There does not appear to be an 
obvious option that I can see. I know Xemacs has this functionality. Is 
there a way to do this in emacs also?

Regards,

Fabrizio

No.  You can make do with C-x < and C-x > (or C-prior C-next) in the
meanwhile.

Horizontal scroll bars

[Tom Browder]

I want horizontal scroll bars on my Debian 8 emacs (loaded as a deb
package). I tried this in my init.el file:

;;============
(load "scroll-bar")
(add-to-list 'initial-frame-alist
    '(horizontal-scroll-bars . t)
    )
;;============

and get nothing.

I've tried:

M-x horizontal-scroll-bars-available-p

and get no [no-match]

Do I have to build emacs from source to get it?

Thanks.

Best regards,

-Tom

Try

M-x horizontal-scroll-bar-mode

That function is not interactive. You need to evaluate

(horizontal-scroll-bars-available-p)

to see its result.

Possibly. horizontal-scroll-bars-available-p returns nil on my build
configured with

--without-toolkit-scroll-bars --with-x-toolkit=lucid

Does "M-x customize-option RET horizontal-scroll-bar-mode RET" work?
If not, what is your Emacs version?

No, it does not.

See next reply.

Okay, I've built emacs 25.1 but still no horizontal scroll bars.

Here is my configuration:

    --with-x-toolkit=lucid \
    --without-dbus         \
    --without-gconf        \
    --without-gsettings    \
    --without-sound

With

Mx (horizontal-scroll-bars-available-p)

I still get no match!

Any ideas?

Thanks.

I don't see any.

Do you mean that M-x horizontal-scroll-bar-mode didn't work?

As mentioned on my previous reply,
`horizontal-scroll-bars-available-p' is not an interactive function. It
doesn't work from the M-x interface. You need to evaluate it. For
instance, switch to the *scratch* buffer, paste

(horizontal-scroll-bars-available-p)

put the cursor after the last paren and press C-x C-e

> Any ideas?

Maybe you need to build with GTK (which IIRC is the default when you
have the GTK development libraries installed.) On an empty build
directory, try invoking `path/to/emacs/source/configure' without
parameters and see if the summary mentions GTK. If yes, just complete
the build by running `make'.

Not "Mx", "M-:".

Also, what does this display:

  M-: (boundp 'x-toolkit-scroll-bars) RET

 From NEWS:

*** Emacs can now draw horizontal scroll bars on some platforms that
provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.

So you have to build with toolkit scroll bars.
