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