Fellow Linuxers,

below is the README file of the new version of Xaw3d for Linux that
i have uploaded yesterday to sunsite.unc.edu.

               Three-D Athena Widgets (Xaw3d) for Linux
                         Xaw3d-0.6B-3.1.1

These are the sources and binaries of Kaleb Keithley's Xaw3d library
for Linux. Xaw3d is a true replacement for the Athena widget library
Xaw which gives your Athena based applications 3D appearance similar
to another well known commercial widget library.

Version Xaw3d-0.6B-3.1.1 is based on Xaw3d-0.6B-3.0.1 of

plus the following patches of mine:

  o Patches for the Layout widget

    - The Layout Widget had a non Xt-conform String-to-Layout converter
    - A fix for laylex.l under AIX where the last character of all
      identifiers was globbered
    - initialization bug which caused incorrect width and height
      calculation in Layout widgets

  o Patches for the Clock widget

      Clock widget has the following additional resosurces:

         hourOffset     Int
         minuteOffset   Int
         gmt            Boolean

       hourOffset and minuteOffset describe the offsets of the displayed
       time relative to the actual time, if gmt is set, gmtime() is used
       instead of localtime() to compute tm. if gmt is set to false
       (the default), the offsets are relative to localtime.

       This patch allows to have a single application to display various
       clocks showing different times.

  o Several attempts to improve the appearance of 3d shadows:

       a) for white or black background, the top shadow was darker
          than the bottom shadow

       b) the bitmaps used for back and white background were bad,
          they contained patterns with sequences which where a
          multiple of 3, but tiled with a multiple of 4

       c) The shadows on white or black backgrounds were really ugly.
          Setting beNiceToColormap to false is not always the best
          solution, therefore i added some kind of a compromise,
          which uses a single additional color cell (gray) to achieve the
          intended effects.

     Using the gray colorcell can activated by compiling Xaw3d with the
     option -DUSEGRAY.

  o Patch for the AsciiText widget class:

     If for a AsciiText widget the resource "resize" is set
     (eg. to "width"), the AsciiText widget tries now to resize itself,
     when the "string" resouce is altered.

In order to install the shared and static libraries, unpack
the binary distribution, cd to ./Xaw3d and  issue the the
following commands with root privileges:

    cp libXaw3d.sa libXaw3d.a /usr/lib
    cp libXaw3d.so.3.1.1 /lib/
    ldconfig

libXaw3d is fully compatible with libXaw from XFree 2.0. In order
to add 3d appearance to applications compiled with Xaw, it is
sufficient to replace the shared library of libXaw with the 3d
variant. Since Xaw3d has a higher revision number than libXaw,
it is sufficient to issue the following commands to use the
3d library:

    ln -sf /lib/libXaw3d.so.3.1.1 /lib/libXaw.so.3.1.1
    ldconfig

The library was built using gcc 2.5.8, libc 4.5.19, tools 2.10
under Linux 0.99.15.
