| 26 ;; This file does the magic to parse X font names, and make sure that the | |
| 27 ;; default and modeline attributes of new frames are specified enough. | |
| 28 ;; | |
| 29 ;; The resource-manager syntax for faces is | |
| 30 ;; | |
| 31 ;; Emacs.bold.attributeFont: font-name | |
| 32 ;; Emacs.bold.attributeForeground: fg | |
| 33 ;; Emacs.bold.attributeBackground: bg | |
| 34 ;; Emacs.bold.attributeBackgroundPixmap: file | |
| 35 ;; Emacs.bold.attributeUnderline: true/false | |
| 36 ;; Emacs.bold.attributeStrikethru: true/false | |
| 37 ;; | |
| 38 ;; You can specify the properties of a face on a per-frame basis. For | |
| 39 ;; example, to have the "isearch" face use a red foreground on frames | |
| 40 ;; named "emacs" (the default) but use a blue foreground on frames that | |
| 41 ;; you create named "debugger", you could do | |
| 42 ;; | |
| 43 ;; Emacs*emacs.isearch.attributeForeground: red | |
| 44 ;; Emacs*debugger.isearch.attributeForeground: blue | |
| 45 ;; | |
| 46 ;; Generally things that make faces won't set any of the face attributes if | |
| 47 ;; you have already given them values via the resource database. You can | |
| 48 ;; also change this stuff from your .emacs file, by using the functions | |
| 49 ;; set-face-foreground, set-face-font, etc. See the code in this file, and | |
| 50 ;; in faces.el. | |
