-
- Announcing Release 0.1 (beta) of a 3-D widget set based on Xaw.
-
-
- Three-D Athena Widgets (Xaw3d)
- kaleb@thyme.jpl.nasa.gov
-
- Features:
-
- This is Release 0.1 beta (28 July, 1992) 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 of the Athena (Xaw) Widget set.
-
- In general, it is possible to relink any Athena Widget based application
- with the Three-D Athena Widget set to obtain a three dimensional appearance.
-
- The Three-D Athena Widget set uses a ThreeD subclass to add the following
- widget resources: top shadow color, bottom shadow color, shadow width, top
- shadow contrast, bottom shadow contrast, user data, and a "be nice to the
- colormap" option.
-
- In previous releases I have relinked all of the clients in the MIT sample
- implementation release with the Three-D Athena Widget set, and with Brian V.
- Smith's xfig. In this release, due to time constraints, I have only tested
- editres and xfig. I can assert that none of them "broke".
-
- Top shadow color, bottom shadow color, shadow width, top shadow bright and
- bottom shadow dim 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 pixmap shadows for 1-bit deep visuals
- o selection (on a per-widget basis) of "colormap friendly" versus
- "colormap unfriendly" shadow drawing mode.
- o use a tiled pixmap to create shadows colors in "colormap friendly"
- mode.
- o settable shadow contrast (intensity) when using "filled" shadows
- in "colormap unfriendly" mode.
- o allow Labels to have shadows (again), but you must over-ride the
- default shadow width of zero.
- o All 3d code linted clean with 'gcc -Wall -pedantic -traditional...'
- and Sun lint.
-
-
- This release fixes the following bugs:
-
- o fixed shadow-draw and interior-draw bugs in scrollbar and stripchart.
- o fixed Command enter hi-lighting.
-
-
- Known bugs:
-
- o I don't have any monochrome systems -- therefore I haven't tested
- the 1-bit visual pixmap shadows.
-
-
- 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-0.1.tar.Z
-
-
- 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 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:
-
- It's okay to just relink your application with -lXaw3d. I'll even go
- so far as to say just hack your Imake generated Makefile and change the
- Xaw to Xaw3d. As an alternative, if you're using shared libraries,
- you may install libXaw3d.s?.5.0 as libXaw.s?.5.0, and your applications
- that are dynamically linked will inherit the 3-D appearance automatically
- the next time you run them.
-
-
- Extra Credit:
-
- I recommend adding Xaw3d symbols to .../mit/config/Project.tmpl,
- and, if you're on a Sun or a SVR4 box, SunLib.tmpl or sv4Lib.tmpl too.
- You'll want to create parallel symbols for most of the Athena
- symbols. Symbols you'll want 3d versions of might include:
- AWIDGETSRC ---> A3DWIDGETSRC
- DEPXAWLIB ---> DEPXAW3DLIB
- XAWLIB ---> XAW3DLIB
- LINTXAW ---> LINTXAW3D
- XawClientLibs ---> Xaw3dClientLibs
- XawClientDepLibs ---> Xaw3dClientLibs
-
- I'll leave it as an exercise as to the values for those symbols.
