This is discussed in the file "widget_fonts.doc" in the directory
$IDL_DIR/notes on the Sun. Unfortunately, the documentation only refers to
Unix system, and the differences for VMS are not discussed. However, I
reproduce the documentation below.

Running the Sun version of IDL on a Non-OpenWindows Display Server
IDL version 2.x on the Sun is usually run from OpenWindows. If IDL
is run with a different X server, such as X11R4 from MIT,
IDL Widget applications will not work correctly unless the OpenWindows
fonts for buttons and scrollbars are available to the display server.
This situation might occur if OpenWindows is replaced with a different
X server or if a different machine without OpenWindows is used as the
display server.
This situation is complicated by the fact that different font formats
are used by Sun (Sun X11/News), DEC (pcf) and the standard X11
server from MIT (bdf). The process is the the same for converting
to DecWindows or the MIT server, although the actual commands differ
in name.
The required fonts are supplied with OpenWindows. It is necessary to
convert them to the correct format for your server. The procedure for
converting the fonts to the appropriate format is described below.
Many thanks to Dave Biron of MIT Lincoln Laboratories who came up with
this approach and documented it.
This description assumes that the OpenWindows distribution is installed
in the directory OPENWINHOME. This is a Unix environment variable that
contains the location of the root OpenWindows directory. On many
systems, this is defined as:
% setenv OPENWINHOME /usr/openwin
You should make sure it is defined properly for your system before
starting this procedure.
On the machine running the non-OpenWindows server, we assume the
location of the X11 installation is X11HOME. On many systems, this
is defined as:
% setenv X11HOME /usr/lib/X11
You should make sure it is defined properly for your system before
starting this procedure.
ON THE MACHINE WITH OPENWINDOWS:
--------------------------------
1. Find the fonts in the OpenWindows distribution. They are usually in the
$OPENWINHOME/lib/fonts directory, with names like "d12butto12.fb"
or "d12sbarv12.fb". The important files have extensions of ".fb"; don't
worry about the ".ff" files. There are 61 files whose names should match
the list of ".snf" files shown below except for the ".fb" suffix. Use
the following command to list the files:
ls $OPENWINHOME/lib/fonts/?12*.fb
Use the command "xlsfonts" to list the actual names of the fonts:
$OPENWINHOME/bin/xlsfonts | grep '[a-h]'12
2. Use the OpenWindows utility "convertfont" to create ".bdf" format
font files from the ".fb" files. First make a subdirectory of the
fonts directory, and create the new files there. This process must
be done as superuser, unless it is done in a user's directory.
% cd $OPENWINHOME/lib/fonts
% mkdir bdf_fonts_for_widgets
% cd !$
% foreach name (../?12*.fb)
? $OPENWINHOME/bin/convertfont -x -o `basename $name .fb` $name
? end
3. Copy the ".bdf" format font files to the machine that will run as the
display server for IDL. If only one machine is being used to run both
OpenWindows and X11, skip this step.
% cd /usr/lpp/fonts
% mkdir openwin
% cd !$
% rcp mysun:"$OPENWINHOME/lib/fonts/bdf_fonts_for_widgets/*" .
ON THE MACHINE WITH X11:
------------------------
4. Convert the ".bdf format font files to the correct format for your
server.
FOR THE MIT SERVER:
% cd /usr/lpp/fonts/openwin
% foreach name (*.bdf)
? echo $name
? bdftosnf $name > `basename $name .bdf`.snf
? end
FOR THE DecWindows SERVER:
% cd /usr/lpp/fonts/openwin
% foreach name (*.bdf)
? echo $name
? dxfc $name > `basename $name .bdf`.pcf
? end
5. Generate the file "fonts.dir". This file contains a line for each
font file in the directory, and maps the actual name of each font
to the file containing it:
FOR THE MIT SERVER:
% mkfontdir `pwd`
FOR THE DecWindows SERVER:
% dxmkfontdir `pwd`
6. Edit the "fonts.dir" file to make the font names (the second field on each
line) match the OpenWindows font names. On some servers, the font names
end with "-10", "-12", or "-14", but the Sun version of IDL looks for
fonts without that suffix.
To make the font names in the file "fonts.dir" match the OpenWindows
font names from step 1, simply edit the "fonts.dir" file and correct
the names. (It is probably possible to use a "fonts.alias" file, but
editing the "fonts.dir" file seemed like the most simple approach.)
For example, to use vi to remove the "-1?" suffixes, enter:
vi fonts.dir
:g/-..$/s///
7. Add the directory containing the fonts to the font path of the server
and rehash the font path to add the fonts.
xset +fp /usr/lpp/fonts/openwin
xset fp rehash
These "xset" commands could be placed in a user's startup file so that
the fonts are added when the server is initialized. On some systems,
including the IBM RS6000 the commands could be put in the ".xinitrc"
file. For other systems, such as Ultrix machines, the commands should
be put in the ".X11start" file. On the SGI, the files were placed in
an existing font directory, and then the "fonts.dir" file was updated
to include the new fonts. Use "xset q" to make sure that the font
path has been modified as desired. Use the same "xlsfonts" command
shown in step one to make sure that the fonts are installed in the
server.
ADDITIONAL NOTES
----------------
After the fonts are installed, they can be viewed using the X11
utility "xfd".
The MIT X11 server can read ".bdf" format fonts but the ".snf" format
is more compact.
Some installations might be missing the utility "xset". Usually the
source can be found and compiled. You might have to remove a call
to XmuPrintDefaultErrorMessage to allow xset.c to compile.
On Suns running MIT X11, many of these utility programs require that
the environment variable LD_LIBRARY_PATH be set to the lib
subdirectory of the X installation. For example, on the machine
running OpenWindows, enter:
setenv LD_LIBRARY_PATH $OPENWINHOME/lib
On other machines which normally run X11, enter:
setenv LD_LIBRARY_PATH /usr/lib
IDL may also look for a set of pushpin bitmaps. If your
system has the OpenWindows distribution installed they should be available
in $OPENWINHOME/lib/bitmaps. Simply define the environment variable
OPENWINHOME and the toolkits should then be able to access them.
On other machines which normally run X11 copy the bitmaps to a bitmaps
subdirectory of the lib directory of the X installation. Then enter:
setenv OPENWINHOME $X11HOME/lib
LIST OF FONT FILES
------------------
The following is a list of the converted fonts and their OpenWindows font
names for Open Windows 2.0. (It is actually the file "fonts.dir".)
Some of these may not be required, but if all are converted IDL Widgets
will run.
