widget-name is used as described for GTK+ in Matching resources on GTK+, except that the default widget-name for a top level interface does include the prepended application-class .
The file
app-defaults/Lispworks
, supplied in the LispWorks library for relevant platforms, contains the application fallback resources for LispWorks 6.1 and illustrates resources you may wish to change.
The files
app-defaults/*-classic
contain the fallback resources that were supplied with LispWorks 4.4.
For further information about X resources, consult documentation for the X Window system.
