37 ;; This file does the magic to parse X font names, and make sure that the
38 ;; default and modeline attributes of new frames are specified enough.
40 ;; The resource-manager syntax for faces is
42 ;; Emacs.bold.attributeFont: font-name
43 ;; Emacs.bold.attributeForeground: fg
44 ;; Emacs.bold.attributeBackground: bg
45 ;; Emacs.bold.attributeBackgroundPixmap: file
46 ;; Emacs.bold.attributeUnderline: true/false
47 ;; Emacs.bold.attributeStrikethru: true/false
49 ;; You can specify the properties of a face on a per-frame basis. For
50 ;; example, to have the "isearch" face use a red foreground on frames
51 ;; named "emacs" (the default) but use a blue foreground on frames that
52 ;; you create named "debugger", you could do
54 ;; Emacs*emacs.isearch.attributeForeground: red
55 ;; Emacs*debugger.isearch.attributeForeground: blue
57 ;; Generally things that make faces won't set any of the face attributes if
58 ;; you have already given them values via the resource database. You can
59 ;; also change this stuff from your .emacs file, by using the functions
60 ;; set-face-foreground, set-face-font, etc. See the code in this file, and
