| 35 ;; This file does the magic to parse X font names, and make sure that the | |
| 36 ;; default and modeline attributes of new frames are specified enough. | |
| 37 | |
| 38 ;; The resource-manager syntax for faces is | |
| 39 | |
| 2703 | 40 ;; XEmacs.bold.attributeFont: font-name |
| 41 ;; XEmacs.bold.attributeForeground: fg | |
| 42 ;; XEmacs.bold.attributeBackground: bg | |
| 43 ;; XEmacs.bold.attributeBackgroundPixmap: file | |
| 44 ;; XEmacs.bold.attributeUnderline: true/false | |
| 45 ;; XEmacs.bold.attributeStrikethru: true/false | |
| 428 | 46 |
| 47 ;; You can specify the properties of a face on a per-frame basis. For | |
| 48 ;; example, to have the "isearch" face use a red foreground on frames | |
| 2703 | 49 ;; named "XEmacs" (the default) but use a blue foreground on frames that |
| 428 | 50 ;; you create named "debugger", you could do |
| 51 | |
| 2703 | 52 ;; XEmacs*XEmacs.isearch.attributeForeground: red |
| 53 ;; XEmacs*debugger.isearch.attributeForeground: blue | |
| 428 | 54 |
| 55 ;; Generally things that make faces won't set any of the face attributes if | |
| 56 ;; you have already given them values via the resource database. You can | |
| 57 ;; also change this stuff from your .emacs file, by using the functions | |
| 58 ;; set-face-foreground, set-face-font, etc. See the code in this file, and | |
