This, in my ~/.Xdefaults:
#ifdef XEMACS_XFT
XEmacs.default.attributeFont: Courier-12
XEmacs*font: Helvetica-12:style=bold
#else
XEmacs.default.attributeFont: -adobe-courier-medium-r-normal--12-120-75-75-m-70-iso8859-1
XEmacs*font: -adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso8859-1
#endif
gives me two identical frames on my local machine, with one frame
belonging to an XEmacs build with server-side fonts and with X defaults
not reflecting XEMACS_XFT, and the other frame belonging to an XEmacs build
with Xft fonts and with X defaults reflecting XEMACS_XFT. This requires a)
that XFT believes that the display has the same DPI as does the X server and
b) that XFT has access to the same font files on disk.
The fonts used by the menubars are not accessible from Lisp right now,
sorry. But for the default face, (set-face-font 'default nil "Courier-12")
should do the job.
To check what DPI the X server-side fonts think your display has, try
xdpyinfo | grep 'dots per inch'
To check what DPI the X client-side fonts think your display has,
appres Xft
If that gives you a value for DPI, that’s what’s used by client-side fonts;
if it doesn’t, the server side DPI value will be used.
To check what font file XFT uses for a given pattern, try, for example,
fc-match -v 'Helvetica-12:style=bold' | grep file
This gives file: "/usr/X11R6/lib/X11/fonts/75dpi/helvB12.pcf.gz"
for me. When I grep for helvB12.pcf.gz in
/usr/X11R6/lib/X11/fonts/75dpi/helvB12.pcf.gz, I get this:
helvB12.pcf.gz -adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso10646-1
which matches your server-side pattern sufficiently that I’m reasonably sure
it’s the same font.
