No toolkit scrollbars with --with-x-toolkit=lucid

No toolkit scrollbars with --with-x-toolkit=lucid

[Tassilo Horn]

Hi all,

I've heard good things about the Lucid/Athena scrollbars, so I wanted to
try them out.  I configured my bzr copy with

  --with-sound --with-x --without-gconf --with-toolkit-scroll-bars 
  --with-gif --with-jpeg --with-png --with-rsvg --with-tiff --with-xpm 
  --with-xft --with-libotf --with-m17n-flt --with-x-toolkit=lucid 
  --without-hesiod --without-kerberos --without-kerberos5 --with-gpm 
  --with-dbus

Unfortunately, after configuring it says it will build without toolkit
scrollbars.

  Does Emacs use toolkit scroll bars?                     no

I have libXaw-1.0.7 installed.  Or does libXaw provide no scrollbars and
I need to have Xaw3d?

You have to have Xaw3D to get Xaw scroll bars.  Xaw has scroll bars, but 
I think there where some incompability problems with Xaw3D, and so only 
Xaw3D is used in Emacs.

Ok, thanks for the info.  Then I'll stay with no toolkit scrollbars.

AFAIK the code worked fine with Xaw scrollbars, except that the
configure/make scripts don't provide an option to use them, mostly
because the "no toolkit" scrollbars provide pretty much the exact same
appearance and behavior anyway.

Years ago I contributed code to XEmacs to detect, at runtime, a problem
I encountered in practise: that a version of XEmacs compiled for Xaw, running
against Xaw3D[1], would crash because the ABI changed with the same soname.

I have no idea if this is at all related, but IIRC there were some problems
with Linux distributions, and perhaps beyond, that resulted in this causing
real-world issues.

This may, or may not, have anything to do with why the feature is disabled in
GNU Emacs, but may be a point worth noting.[2]

Besides, most of the Xaw problems are dead by now, I suspect, save for the
rare custom build done by individual users.

Footnotes: 
[1]  ...or maybe it was 3D vs some other NextSTEP-like Xaw set.

[2]  ...and I am happy to assign copyright of that code, using my existing
     Emacs contribution agreement, if y'all want to pick it up or anything.
