Three-D Athena Widgets (Xaw3d)
Kaleb S. Keithley
[email protected]
Features:
This is Release 0.6B (17 Feb, 1993) of a set of 3-D widgets based on the
R5 Athena Widget set. The Three-D Athena may be used as a general
replacement for the Athena (Xaw) Widget set.
In general, you may relink almost any Athena Widget based application with
the Three-D Athena Widget set and obtain a three dimensional appearance.
On systems with shared libraries, you can replace your shared libXaw with
libXaw3d and obtain the three dimensional appearance without even relinking.
In this release, I have tested all of the clients distributed on the R5 MIT
source tape, plus xfig-2.1.5, xarchie-1.3, and aXe-3.1. All Xaw3d sources
have been thoroughly delinted using Sun's /bin/lint and gcc using -traditional
-pedantic -Wall and -ansi -pedantic -Wall.
Top and bottom shadow colors, shadow width, top and bottom shadow contrast
should be self explanatory, and may be set via the usual and customary
methods, e.g. app-defaults, .Xdefaults, programmatically, with editres,
etc. The user data resource may be used to "hang" application specific
data on a widget, and is only settable programmatically.
This release adds the following features:
o The 0.6A release fixed a problem in the Imakefile and added comments
to the README. No changes were made to the Xaw3d sources.
o The 0.6B release added a comment to the README. No changes were
make to the Xaw3d sources.
o The Layout widget. If I may borrow the phrase, this is an insanely
great widget written by Keith Packard, and introduced at the '93
X Technical Conference. I have included it in Xaw3d, with Keith's
permission, because Xaw has been in need of a versatile manager
widget. Subclassed from Constraint, the Layout widget uses TeX-
like semantics to describe where to place children and how to do
geometry management.
o Scrollbar with arrows. This is an Athena-based arrowhead-style
Scrollbar written by Mitch Trachtenberg that is 100% compatible
with the normal Athena Scrollbar. Selection of the normal style
or the arrow style Scrollbar is a compile-time option for Xaw3d.
The arrow style scrollbar is available separately on export in
the file: /contrib/Xaw.Scrollbar.mta.Z
o Bug fixes. More bug fixes than you can shake a stick at.
Known problems:
o You won't be able to replace shared libXaw with libXaw3d on systems
with SVR3 style shared libraries.
o On SVR4/386, I've had reports that replacing shared libXaw with
libXaw3d works, and I've had reports that it doesn't. Try it and
see.
o Xaw3d pixel allocation doesn't behave well when beNiceToColormap
is False and the Default Colormap is full.
o The samples in Layout.h are wrong and don't work. Example programs
written by Keith Packard that use the Layout widget are available
on export in /contrib/Layout.tar.Z
aXe-3.1 and xarchie:
aXe-3.1 and xarchie won't compile against Xaw3d because they subclass
the Xaw widgets themselves. To solve this, I now have a pair of
patches for these programs. See below for where to get these patches.
Renaming/replacing shared libXaw with libXaw3d will definitely break
unpatched aXe-3.1 and xarchie.
aXe-4.0 includes optional support for Xaw3d. Consult the aXe README
for more information.
xterm:
A comment that appears in the xterm source:
*
* ...There be serious and nasty dragons here.
*
xterm is, well, xterm. The auto-scroll in the arrow-style scrollbar
doesn't work in xterm because it relies on XtTimeouts. xterm, perhaps
in the name of speed, circumvents XtAppNextEvent() and goes direct to
XNextEvent() to get it's XEvents, with the unfortunate side effect of
completely ignoring "other sources" like timeouts. I have included a
patch for xterm to support the arrow-style scrollbar. See below for
where to get this patch.
Getting:
Xaw3d may be found on export.lcs.mit.edu (18.24.0.12) and possibly other
sites; check archie. On export, it may be found in the file:
~ftp/contrib/Xaw3d/R5/Xaw3d-0.6B.tar.Z
There is no patch file from 0.5 to 0.6 -- it's larger than the tar file.
Patches for xarchie-1.3, aXe-3.1, and xterm may be found in the files:
~ftp/contrib/Xaw3d/R5/xarchie3d.patch
~ftp/contrib/Xaw3d/R5/aXe3d.patch
~ftp/contrib/Xaw3d/R5/xterm.patch
Building:
Untar the distribution from the base of your MIT source tree. This will
create the directory .../mit/lib/Xaw3d. 'cd' there and:
'make Makefile; make includes; make depend; make; make install'.
The Imakefile contains the line:
# EXTRA_DEFINES = -DARROW_SCROLLBAR
If you want the arrow-scrollbar, then uncomment the line by deleting the '#'.
The Imakefile uses the Xaw symbols in .../mit/config, so if you have
debugging, profiling, shared libs, etc. specified for Xaw, you'll get
them in Xaw3d too.
Using:
Just relink your Xaw based application with -lXaw3d.
To obtain an appearance similar to another well know widget set, use the
following resources:
*background: LightSkyBlue
*shapeStyle: Rectangle
*beNiceToColormap: False
By default, Label widgets do not have shadows drawn for them. You can
force shadows to be drawn for specifying:
*shadowWidth: 2
If you'd like the default behavior (i.e. not 3-D) on pulldown menus, use:
*SmeBSB*shadowWidth: 0
