Use of Motif with LispWorks is deprecated on these platforms, but you can still use it.
LispWorks uses GTK+ as the default window system for CAPI and the LispWorks IDE on Linux, FreeBSD and x86/x64 Solaris.
To use Motif instead you need to load it explicitly, by:
(require "capi-motif")
Requiring the
"capi-motif"
module makes CAPI use Motif as its default library.
You can override the default library by specifying the appropriate CAPI screen. For more information about this, see the
screen
argument to
display
and
convert-to-screen
.
