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. | |
39 | |
40 ;; The resource-manager syntax for faces is | |
41 | |
2703 | 42 ;; XEmacs.bold.attributeFont: font-name |
43 ;; XEmacs.bold.attributeForeground: fg | |
44 ;; XEmacs.bold.attributeBackground: bg | |
45 ;; XEmacs.bold.attributeBackgroundPixmap: file | |
46 ;; XEmacs.bold.attributeUnderline: true/false | |
47 ;; XEmacs.bold.attributeStrikethru: true/false | |
428 | 48 |
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 | |
2703 | 51 ;; named "XEmacs" (the default) but use a blue foreground on frames that |
428 | 52 ;; you create named "debugger", you could do |
53 | |
2703 | 54 ;; XEmacs*XEmacs.isearch.attributeForeground: red |
55 ;; XEmacs*debugger.isearch.attributeForeground: blue | |
428 | 56 |
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 | |
61 ;; in faces.el. | |
