I have a file called .Idl_defaults in my home directory which contains
the various X-resources used to define some colour settings. I then do
xrdb ~/.Idl_defaults in my .login file
The file contains:
! This is an application defaults file for use with IDL. It makes
! IDL work properly under OpenWindows 3.0, or different variants of Motif.
! It should be copied to the application defaults directory, which is usually
! $OPENWINHOME/lib/app-defaults for OpenWindows, or /usr/lib/X11/app-defaults
! for Motif.
! This sets the number of colors IDL reserves. Leave 5 unallocated color
! table entries for other applications and the windowing system:
Idl.colors: -5
! The following lines are for OpenLook:
Idl*threeD: TRUE
Idl*background: palegreen
Idl*text*background: lightcyan
Idl*button*background: lightcyan
Idl*slider*background: lightcyan
Idl*list*background: lightcyan
I think that you can drop te Idl*threeD as I think that is OpenLook only
the others work for both OL and Motif
