94249313 | 7 | |
82f6e63d | 8 | You can customize some X-related aspects of Emacs behavior using X |
8c1691d8 JR |
9 | resources, as is usual for programs that use X. On MS-Windows, you |
10 | can customize some of the same aspects using the system registry. | |
e8fd09cc | 11 | @xref{MS-Windows Registry}. Likewise, Emacs on MacOS Carbon emulates X |
2d488bd1 | 12 | resources using the Preferences system. @xref{Mac Environment Variables}. |

c6aea8f8 | 14 | When Emacs is built using an ``X toolkit'', such as Lucid or |
e8fd09cc JD |
15 | LessTif, you need to use X resources to customize the appearance of |
16 | the widgets, including the menu-bar, scroll-bar, and dialog boxes. | |
17 | This is because the libraries that implement these don't provide for | |
10214524 | 18 | customization through Emacs. GTK+ widgets use a separate system of |
e8fd09cc JD |

47 | Programs running under the X Window System organize their user |
48 | options under a hierarchy of classes and resources. You can specify | |
49 | default values for these options in your X resources file, usually | |
02e740dc DL |
50 | named @file{~/.Xdefaults} or @file{~/.Xresources}. |
51 | If changes in @file{~/.Xdefaults} do not | |
9b7e4229 RS |
52 | take effect, it is because your X server stores its own list of |
53 | resources; to update them, use the shell command @command{xrdb}---for | |
54 | instance, @samp{xrdb ~/.Xdefaults}. | |
94249313 RS |
55 | |
56 | Each line in the file specifies a value for one option or for a | |
57 | collection of related options, for one program or for several programs | |
58 | (optionally even for all programs). | |

94249313 RS |
61 | MS-Windows systems don't support @file{~/.Xdefaults} files, but |
62 | Emacs compiled for Windows looks for X resources in the Windows | |
eca274b1 RS |
63 | Registry, under the key @samp{HKEY_CURRENT_USER\SOFTWARE\GNU\Emacs} |
64 | and then under the key @samp{HKEY_LOCAL_MACHINE\SOFTWARE\GNU\Emacs}. | |
de222545 | 65 | The menu and scroll bars are native widgets on MS-Windows, so they are |
b15fa8b1 | 66 | only customizable via the system-wide settings in the Display Control |
3eff9df2 RS |
67 | Panel. You can also set resources using the @samp{-xrm} command line |
68 | option (see below.) | |

70 | @iftex |
71 | Applications such as Emacs look for resources with specific names | |
72 | and their particular meanings. Case distinctions are significant in | |
73 | these names. Each resource specification in @file{~/.Xdefaults} | |
74 | states the name of the program and the name of the resource. For | |
75 | Emacs, the program name is @samp{Emacs}. It looks like this: | |
c6aea8f8 | 76 | |
e8fd09cc JD |
77 | @example |
78 | Emacs.borderWidth: 2 | |
79 | @end example | |
80 | @end iftex | |
81 | @ifnottex | |
94249313 RS |
82 | Programs define named resources with particular meanings. They also |
83 | define how to group resources into named classes. For instance, in | |
84 | Emacs, the @samp{internalBorder} resource controls the width of the | |
85 | internal border, and the @samp{borderWidth} resource controls the width | |
86 | of the external border. Both of these resources are part of the | |
87 | @samp{BorderWidth} class. Case distinctions are significant in these | |
88 | names. | |
89 | ||
10214524 RS |
90 | Every resource definition is associated with a specific program |
91 | name---the name of the executable file that you ran. For Emacs, that | |
92 | is normally @samp{emacs}. To specify a definition for all instances | |
93 | of Emacs, regardless of their names, use @samp{Emacs}. | |
94 | ||
94249313 RS |
95 | In @file{~/.Xdefaults}, you can specify a value for a single resource |
96 | on one line, like this: | |
97 | ||
98 | @example | |
99 | emacs.borderWidth: 2 | |
100 | @end example | |
101 | ||
102 | @noindent | |
103 | Or you can use a class name to specify the same value for all resources | |
104 | in that class. Here's an example: | |
105 | ||
106 | @example | |
107 | emacs.BorderWidth: 2 | |
108 | @end example | |
109 | ||
110 | If you specify a value for a class, it becomes the default for all | |
111 | resources in that class. You can specify values for individual | |
112 | resources as well; these override the class value, for those particular | |
113 | resources. Thus, this example specifies 2 as the default width for all | |
114 | borders, but overrides this value with 4 for the external border: | |
115 | ||
116 | @example | |
117 | emacs.BorderWidth: 2 | |
118 | emacs.borderWidth: 4 | |
119 | @end example | |
e8fd09cc | 120 | @end ifnottex |
94249313 RS |
121 | |
122 | The order in which the lines appear in the file does not matter. | |
123 | Also, command-line options always override the X resources file. | |

10214524 RS |
126 | Here is a list of X command-line options and their corresponding |
127 | resource names. | |
94249313 RS |
128 | |
129 | @table @samp | |
130 | @item -name @var{name} | |
131 | @opindex --name | |
132 | @itemx --name=@var{name} | |
133 | @cindex resource name, command-line argument | |
134 | Use @var{name} as the resource name (and the title) for the initial | |
135 | Emacs frame. This option does not affect subsequent frames, but Lisp | |
136 | programs can specify frame names when they create frames. | |
137 | ||
138 | If you don't specify this option, the default is to use the Emacs | |
139 | executable's name as the resource name. | |
140 | ||
141 | @item -xrm @var{resource-values} | |
142 | @opindex --xrm | |
143 | @itemx --xrm=@var{resource-values} | |
144 | @cindex resource values, command-line argument | |
145 | Specify X resource values for this Emacs job (see below). | |
146 | @end table | |
147 | ||
148 | For consistency, @samp{-name} also specifies the name to use for | |
149 | other resource values that do not belong to any particular frame. | |
150 | ||
151 | The resources that name Emacs invocations also belong to a class; its | |
152 | name is @samp{Emacs}. If you write @samp{Emacs} instead of | |
153 | @samp{emacs}, the resource applies to all frames in all Emacs jobs, | |
154 | regardless of frame titles and regardless of the name of the executable | |
155 | file. Here is an example: | |
156 | ||
157 | @example | |
158 | Emacs.BorderWidth: 2 | |
159 | Emacs.borderWidth: 4 | |
160 | @end example | |
161 | ||
162 | You can specify a string of additional resource values for Emacs to | |
163 | use with the command line option @samp{-xrm @var{resources}}. The text | |
164 | @var{resources} should have the same format that you would use inside a file | |
165 | of X resources. To include multiple resource specifications in | |
166 | @var{resources}, put a newline between them, just as you would in a file. | |
167 | You can also use @samp{#include "@var{filename}"} to include a file full | |
168 | of resource specifications. Resource values specified with @samp{-xrm} | |
169 | take precedence over all other resource specifications. | |
170 | ||

464 | The Lucid menus can display multilingual text in your locale. For |
465 | more information about fontsets see the man page for | |
466 | @code{XCreateFontSet}. To enable multilingual menu text you specify a | |
467 | @code{fontSet} resource instead of the font resource. If both | |
468 | @code{font} and @code{fontSet} resources are specified, the | |
469 | @code{fontSet} resource is used. | |
470 | ||
471 | Thus, to specify @samp{-*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*} | |
472 | for both the popup and menu bar menus, write this: | |
0d0e15c3 JD |

f2daf7e9 LT |
509 | Thickness of shadow line around the widget. Default is 1. |

511 | Also determines the thickness of shadow lines around other objects, | |
512 | for instance 3D buttons and arrows. If you have the impression that | |
513 | the arrows in the menus do not stand out clearly enough or that the | |
514 | difference between ``in'' and ``out'' buttons is difficult to see, set | |
515 | this to 2. If you have no problems with visibility, the default | |
516 | probably looks better. The background color may also have some effect | |
517 | on the contrast. | |
e8fd09cc | 518 | @end ifnottex |

529 | If the Emacs installed at your site was built to use the X toolkit | |
530 | with the LessTif or Motif widgets, then the menu bar, the dialog | |
531 | boxes, the pop-up menus, and the file-selection box are separate | |
532 | widgets and have their own resources. | |
533 | ||
534 | The resource names for the menu bar contain @samp{pane.menubar} | |
535 | (following, as always, the name of the Emacs invocation, or | |
536 | @samp{Emacs}, which stands for all Emacs invocations). Specify them | |
537 | like this: | |
538 | ||
539 | @smallexample | |
540 | Emacs.pane.menubar.@var{subwidget}.@var{resource}: @var{value} | |
541 | @end smallexample | |
542 | ||
543 | Each individual string in the menu bar is a subwidget; the subwidget's | |
544 | name is the same as the menu item string. For example, the word | |
545 | @samp{File} in the menu bar is part of a subwidget named | |
546 | @samp{emacs.pane.menubar.File}. Most likely, you want to specify the | |
547 | same resources for the whole menu bar. To do this, use @samp{*} instead | |
548 | of a specific subwidget name. For example, to specify the font | |
549 | @samp{8x16} for the menu-bar items, write this: | |
550 | ||
551 | @smallexample | |
552 | Emacs.pane.menubar.*.fontList: 8x16 | |
553 | @end smallexample | |
554 | ||
555 | @noindent | |
556 | This also specifies the resource value for submenus. | |
557 | ||
558 | Each item in a submenu in the menu bar also has its own name for X | |
559 | resources; for example, the @samp{File} submenu has an item named | |
560 | @samp{Save (current buffer)}. A resource specification for a submenu | |
561 | item looks like this: | |
562 | ||
563 | @smallexample | |
564 | Emacs.pane.menubar.popup_*.@var{menu}.@var{item}.@var{resource}: @var{value} | |
565 | @end smallexample | |
566 | ||
567 | @noindent | |
568 | For example, here's how to specify the font for the @samp{Save (current | |
569 | buffer)} item: | |
570 | ||
571 | @smallexample | |
572 | Emacs.pane.menubar.popup_*.File.Save (current buffer).fontList: 8x16 | |
573 | @end smallexample | |
574 | ||
575 | @noindent | |
576 | For an item in a second-level submenu, such as @samp{Complete Word} | |
577 | under @samp{Spell Checking} under @samp{Tools}, the resource fits this | |
578 | template: | |
579 | ||
580 | @smallexample | |
581 | Emacs.pane.menubar.popup_*.popup_*.@var{menu}.@var{resource}: @var{value} | |
582 | @end smallexample | |
583 | ||
584 | @noindent | |
585 | For example, | |
586 | ||
587 | @smallexample | |
588 | Emacs.pane.menubar.popup_*.popup_*.Spell Checking.Complete Word: @var{value} | |
589 | @end smallexample | |

594 | It's impossible to specify a resource for all the menu-bar items |
595 | without also specifying it for the submenus as well. So if you want the | |
596 | submenu items to look different from the menu bar itself, you must ask | |
597 | for that in two steps. First, specify the resource for all of them; | |
598 | then, override the value for submenus alone. Here is an example: | |
599 | ||
600 | @smallexample | |
601 | Emacs.pane.menubar.*.fontList: 8x16 | |
602 | Emacs.pane.menubar.popup_*.fontList: 8x16 | |
603 | @end smallexample | |
604 | ||
605 | @noindent | |
606 | For LessTif pop-up menus, use @samp{menu*} instead of | |
607 | @samp{pane.menubar}. For example, to specify the font @samp{8x16} for | |
608 | the pop-up menu items, write this: | |
609 | ||
610 | @smallexample | |
611 | Emacs.menu*.fontList: 8x16 | |
612 | @end smallexample | |
613 | ||
614 | @noindent | |
615 | For LessTif dialog boxes, use @samp{dialog} instead of @samp{menu}: | |
616 | ||
617 | @example | |
618 | Emacs.dialog*.fontList: 8x16 | |
619 | Emacs.dialog*.foreground: hotpink | |
620 | @end example | |
621 | ||
622 | To specify resources for the LessTif file-selection box, use | |
623 | @samp{fsb*}, like this: | |
624 | ||
625 | @example | |
626 | Emacs.fsb*.fontList: 8x16 | |

662 | The most common way to customize the GTK widgets Emacs uses (menus, dialogs | |
663 | tool bars and scroll bars) is by choosing an appropriate theme, for example | |
664 | with the GNOME theme selector. You can also do Emacs specific customization | |
665 | by inserting GTK style directives in the file @file{~/.emacs.d/gtkrc}. Some GTK | |
666 | themes ignore customizations in @file{~/.emacs.d/gtkrc} so not everything | |
667 | works with all themes. To customize Emacs font, background, faces, etc., use | |
668 | the normal X resources (@pxref{Resources}). We will present some examples of | |
669 | customizations here, but for a more detailed description, see the online manual | |
670 | ||
671 | The first example is just one line. It changes the font on all GTK widgets | |
672 | to courier with size 12: | |
673 | ||
674 | @smallexample | |
675 | gtk-font-name = "courier 12" | |
676 | @end smallexample | |
677 | ||
678 | The thing to note is that the font name is not an X font name, like | |
679 | -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*, but a Pango font name. A Pango | |
680 | font name is basically of the format "family style size", where the style | |
681 | is optional as in the case above. A name with a style could be for example: | |
682 | ||
683 | @smallexample | |
684 | gtk-font-name = "helvetica bold 10" | |
685 | @end smallexample | |
686 | ||
687 | To customize widgets you first define a style and then apply the style to | |
688 | the widgets. Here is an example that sets the font for menus, but not | |
689 | for other widgets: | |
690 | ||
691 | @smallexample | |
692 | # @r{Define the style @samp{menufont}.} | |
693 | style "menufont" | |
694 | @{ | |
695 | font_name = "helvetica bold 14" # This is a Pango font name | |
696 | @} | |
697 | ||
698 | # @r{Specify that widget type @samp{*emacs-menuitem*} uses @samp{menufont}.} | |
699 | widget "*emacs-menuitem*" style "menufont" | |
700 | @end smallexample | |
701 | ||
702 | The widget name in this example contains wildcards, so the style will be | |
703 | applied to all widgets that match "*emacs-menuitem*". The widgets are | |
704 | named by the way they are contained, from the outer widget to the inner widget. | |
705 | So to apply the style "my_style" (not shown) with the full, absolute name, for | |
706 | the menubar and the scroll bar in Emacs we use: | |
707 | ||
708 | @smallexample | |
709 | widget "Emacs.pane.menubar" style "my_style" | |
710 | widget "Emacs.pane.emacs.verticalScrollBar" style "my_style" | |
711 | @end smallexample | |
c6aea8f8 | 712 | |
e8fd09cc JD |
713 | But to avoid having to type it all, wildcards are often used. @samp{*} |
714 | matches zero or more characters and @samp{?} matches one character. So "*" | |
715 | matches all widgets. | |
716 | ||
717 | Each widget has a class (for example GtkMenuItem) and a name (emacs-menuitem). | |
718 | You can assign styles by name or by class. In this example we have used the | |
719 | class: | |
720 | ||
721 | @smallexample | |
722 | style "menufont" | |
723 | @{ | |
724 | font_name = "helvetica bold 14" | |
725 | @} | |
726 | ||
727 | widget_class "*GtkMenuBar" style "menufont" | |
728 | @end smallexample | |
729 | ||
730 | @noindent | |
731 | The names and classes for the GTK widgets Emacs uses are: | |
732 | ||
733 | @multitable {@code{verticalScrollbar plus}} {@code{GtkFileSelection} and some} | |
734 | @item @code{emacs-filedialog} | |
735 | @tab @code{GtkFileSelection} | |
736 | @item @code{emacs-dialog} | |
737 | @tab @code{GtkDialog} | |
738 | @item @code{Emacs} | |
739 | @tab @code{GtkWindow} | |
740 | @item @code{pane} | |
741 | @tab @code{GtkVHbox} | |
742 | @item @code{emacs} | |
743 | @tab @code{GtkFixed} | |
744 | @item @code{verticalScrollBar} | |
745 | @tab @code{GtkVScrollbar} | |
746 | @item @code{emacs-toolbar} | |
747 | @tab @code{GtkToolbar} | |
748 | @item @code{menubar} | |
749 | @tab @code{GtkMenuBar} | |
750 | @item @code{emacs-menuitem} | |
751 | @tab anything in menus | |
752 | @end multitable | |
753 | ||
754 | GTK absolute names are quite strange when it comes to menus | |
755 | and dialogs. The names do not start with @samp{Emacs}, as they are | |
756 | free-standing windows and not contained (in the GTK sense) by the | |
757 | Emacs GtkWindow. To customize the dialogs and menus, use wildcards like this: | |
758 | ||
759 | @smallexample | |
760 | widget "*emacs-dialog*" style "my_dialog_style" | |
761 | widget "*emacs-filedialog* style "my_file_style" | |
762 | widget "*emacs-menuitem* style "my_menu_style" | |
763 | @end smallexample | |
764 | ||
765 | If you specify a customization in @file{~/.emacs.d/gtkrc}, then it | |
766 | automatically applies only to Emacs, since other programs don't read | |
767 | that file. For example, the drop down menu in the file dialog can not | |
768 | be customized by any absolute widget name, only by an absolute class | |
769 | name. This is because the widgets in the drop down menu do not | |
770 | have names and the menu is not contained in the Emacs GtkWindow. To | |
771 | have all menus in Emacs look the same, use this in | |
772 | @file{~/.emacs.d/gtkrc}: | |
773 | ||
774 | @smallexample | |
775 | widget_class "*Menu*" style "my_menu_style" | |
776 | @end smallexample | |
777 | ||
778 | Here is a more elaborate example, showing how to change the parts of | |
779 | the scroll bar: | |
780 | ||
781 | @smallexample | |
782 | style "scroll" | |
783 | @{ | |
784 | fg[NORMAL] = "red"@ @ @ @ @ # @r{The arrow color.} | |
785 | bg[NORMAL] = "yellow"@ @ # @r{The thumb and background around the arrow.} | |
786 | bg[ACTIVE] = "blue"@ @ @ @ # @r{The trough color.} | |
787 | bg[PRELIGHT] = "white"@ # @r{The thumb color when the mouse is over it.} | |
788 | @} | |

35d3955b | 800 | If Emacs was built to use the GTK widget set, then the menu bar, tool bar, |

803 | file @file{~/.emacs.d/gtkrc}. We recommend that you use | |
804 | @file{~/.emacs.d/gtkrc} for customizations, since @file{~/.gtkrc-2.0} | |
805 | seems to be ignored when running GConf with GNOME. These files apply | |

488dd4c4 | 808 | |

828 | Here is a more elaborate example, showing how to change the parts of | |
829 | the scroll bar: | |

831 | @smallexample |

836 | bg[ACTIVE] = "blue"@ @ @ @ # @r{The trough color.} | |
837 | bg[PRELIGHT] = "white"@ # @r{The thumb color when the mouse is over it.} | |

842 | ||
2d21bf9e EZ |
843 | There are also parameters that affect GTK as a whole. For example, |
844 | the property @code{gtk-font-name} sets the default font for GTK. You | |
845 | must use Pango font names (@pxref{GTK styles}). A GTK resources file | |
846 | that just sets a default font looks like this: | |
488dd4c4 JD |
847 | |
848 | @smallexample | |
849 | gtk-font-name = "courier 12" | |
850 | @end smallexample | |
851 | ||
10214524 RS |
852 | The GTK resources file is fully described in the GTK API document. |
853 | This can be found in | |
854 | @file{@var{prefix}/share/gtk-doc/html/gtk/gtk-resource-files.html}, | |
855 | where @file{prefix} is the directory in which the GTK libraries were | |
856 | installed (usually @file{/usr} or @file{/usr/local}). You can also | |
857 | find the document online, at | |
488dd4c4 JD |

870 | A GTK widget is specified by its @dfn{widget class} and |
871 | @dfn{widget name}. The widget class is the type of the widget: for | |
872 | example, @code{GtkMenuBar}. The widget name is the name given to a | |
873 | specific widget. A widget always has a class, but need not have a | |
874 | name. | |
488dd4c4 | 875 | |
10214524 RS |
876 | @dfn{Absolute names} are sequences of widget names or widget |
877 | classes, corresponding to hierarchies of widgets embedded within | |
878 | other widgets. For example, if a @code{GtkWindow} named @code{top} | |
879 | contains a @code{GtkVBox} named @code{box}, which in turn contains | |
880 | a @code{GtkMenuBar} called @code{menubar}, the absolute class name | |
881 | of the menu-bar widget is @code{GtkWindow.GtkVBox.GtkMenuBar}, and | |
882 | its absolute widget name is @code{top.box.menubar}. | |
488dd4c4 JD |
883 | |
884 | When assigning a style to a widget, you can use the absolute class | |
885 | name or the absolute widget name. | |
10214524 RS |
886 | |
887 | There are two commands to specify changes for widgets: | |
888 | ||
889 | @table @asis | |
890 | @item @code{widget_class} | |
891 | specifies a style for widgets based on the absolute class name. | |
892 | ||
893 | @item @code{widget} | |
894 | specifies a style for widgets based on the absolute class name, | |
895 | or just the class. | |
896 | @end table | |
897 | ||
898 | @noindent | |
3eff9df2 RS |
899 | You must specify the class and the style in double-quotes, and put |
900 | these commands at the top level in the GTK customization file, like | |
10214524 | 901 | this: |
488dd4c4 JD |
902 | |
903 | @smallexample | |
904 | style "menufont" | |
905 | @{ | |
906 | font_name = "helvetica bold 14" | |
907 | @} | |
908 | ||
909 | widget "top.box.menubar" style "menufont" | |
910 | widget_class "GtkWindow.GtkVBox.GtkMenuBar" style "menufont" | |
911 | @end smallexample | |
912 | ||
10214524 RS |
913 | Matching of absolute names uses shell wildcard syntax: @samp{*} |
914 | matches zero or more characters and @samp{?} matches one character. | |
915 | This example assigns @code{base_style} to all widgets: | |
488dd4c4 JD |
916 | |
917 | @smallexample | |
918 | widget "*" style "base_style" | |
919 | @end smallexample | |
920 | ||
921 | Given the absolute class name @code{GtkWindow.GtkVBox.GtkMenuBar} | |
10214524 RS |
922 | and the corresponding absolute widget name @code{top.box.menubar}, all |
923 | these examples specify @code{my_style} for the menu bar: | |
488dd4c4 JD |
924 | |
925 | @smallexample | |
926 | widget_class "GtkWindow.GtkVBox.GtkMenuBar" style "my_style" | |
927 | widget_class "GtkWindow.*.GtkMenuBar" style "my_style" | |
928 | widget_class "*GtkMenuBar" style "my_style" | |
929 | widget "top.box.menubar" style "my_style" | |
930 | widget "*box*menubar" style "my_style" | |
931 | widget "*menubar" style "my_style" | |

940 | In Emacs, the top level widget for a frame is a @code{GtkWindow} |
941 | that contains a @code{GtkVBox}. The @code{GtkVBox} contains the | |
942 | @code{GtkMenuBar} and a @code{GtkFixed} widget. The vertical scroll | |
943 | bars, @code{GtkVScrollbar}, are contained in the @code{GtkFixed} | |
944 | widget. The text you write in Emacs is drawn in the @code{GtkFixed} | |
945 | widget. | |
488dd4c4 JD |
946 | |
947 | Dialogs in Emacs are @code{GtkDialog} widgets. The file dialog is a | |
948 | @code{GtkFileSelection} widget. | |
949 | ||
950 | @noindent | |
951 | To set a style for the menu bar using the absolute class name, use: | |
952 | ||
953 | @smallexample | |
954 | widget_class "GtkWindow.GtkVBox.GtkMenuBar" style "my_style" | |
955 | @end smallexample | |
956 | ||
957 | @noindent | |
958 | For the scroll bar, the absolute class name is: | |
959 | ||
960 | @smallexample | |
177c0ea7 | 961 | widget_class |
488dd4c4 JD |
962 | "GtkWindow.GtkVBox.GtkFixed.GtkVScrollbar" |
963 | style "my_style" | |
964 | @end smallexample | |
965 | ||
966 | @noindent | |
967 | The names for the emacs widgets, and their classes, are: | |
968 | ||
969 | @multitable {@code{verticalScrollbar plus}} {@code{GtkFileSelection} and some} | |
970 | @item @code{emacs-filedialog} | |
971 | @tab @code{GtkFileSelection} | |
972 | @item @code{emacs-dialog} | |
973 | @tab @code{GtkDialog} | |
974 | @item @code{Emacs} | |
975 | @tab @code{GtkWindow} | |
976 | @item @code{pane} | |
977 | @tab @code{GtkVHbox} | |
978 | @item @code{emacs} | |
979 | @tab @code{GtkFixed} | |
a1f3b57e | 980 | @item @code{verticalScrollBar} |
488dd4c4 | 981 | @tab @code{GtkVScrollbar} |
1094ef26 JD |
982 | @item @code{emacs-toolbar} |
983 | @tab @code{GtkToolbar} | |
984 | @item @code{menubar} | |

986 | @item @code{emacs-menuitem} |
987 | @tab anything in menus | |
988 | @end multitable | |
989 | ||
990 | @noindent | |
991 | Thus, for Emacs you can write the two examples above as: | |
992 | ||
993 | @smallexample | |
994 | widget "Emacs.pane.menubar" style "my_style" | |
a1f3b57e | 995 | widget "Emacs.pane.emacs.verticalScrollBar" style "my_style" |
488dd4c4 JD |
996 | @end smallexample |
997 | ||
998 | GTK absolute names are quite strange when it comes to menus | |
177c0ea7 | 999 | and dialogs. The names do not start with @samp{Emacs}, as they are |
488dd4c4 JD |
1000 | free-standing windows and not contained (in the GTK sense) by the |
1001 | Emacs GtkWindow. To customize the dialogs and menus, use wildcards like this: | |
1002 | ||
1003 | @smallexample | |
1004 | widget "*emacs-dialog*" style "my_dialog_style" | |
1005 | widget "*emacs-filedialog* style "my_file_style" | |
1006 | widget "*emacs-menuitem* style "my_menu_style" | |
1007 | @end smallexample | |
1008 | ||
10214524 RS |
1009 | If you specify a customization in @file{~/.emacs.d/gtkrc}, then it |
1010 | automatically applies only to Emacs, since other programs don't read | |
1011 | that file. For example, the drop down menu in the file dialog can not | |
1012 | be customized by any absolute widget name, only by an absolute class | |
3eff9df2 | 1013 | name. This is because the widgets in the drop down menu do not |
10214524 RS |
1014 | have names and the menu is not contained in the Emacs GtkWindow. To |
1015 | have all menus in Emacs look the same, use this in | |
1016 | @file{~/.emacs.d/gtkrc}: | |
488dd4c4 JD |
1017 | |
1018 | @smallexample | |
1019 | widget_class "*Menu*" style "my_menu_style" | |

1026 | In a GTK style you specify the appearance widgets shall have. You | |
10214524 RS |
1027 | can specify foreground and background color, background pixmap and |
1028 | font. The edit widget (where you edit the text) in Emacs is a GTK | |
1029 | widget, but trying to specify a style for the edit widget will have no | |
1030 | effect. This is so that Emacs compiled for GTK is compatible with | |
1031 | Emacs compiled for other X toolkits. The settings for foreground, | |
1032 | background and font for the edit widget is taken from the X resources; | |
1033 | @pxref{Resources}. Here is an example of two style declarations, | |
1034 | @samp{default} and @samp{ruler}: | |
488dd4c4 JD |

10214524 | 1071 | The style @samp{ruler} inherits from @samp{default}. This way you can build |
488dd4c4 JD |
1072 | on existing styles. The syntax for fonts and colors is described below. |
1073 | ||
10214524 RS |
1074 | As this example shows, it is possible to specify several values for |
1075 | foreground and background depending on the widget's @dfn{state}. The | |
1076 | possible states are: | |
1077 | ||
488dd4c4 JD |
1078 | @table @code |
1079 | @item NORMAL | |
1080 | This is the default state for widgets. | |
1081 | @item ACTIVE | |
1082 | This is the state for a widget that is ready to do something. It is | |
177c0ea7 | 1083 | also for the trough of a scroll bar, i.e. @code{bg[ACTIVE] = "red"} |
488dd4c4 JD |
1084 | sets the scroll bar trough to red. Buttons that have been pressed but |
1085 | not released yet (``armed'') are in this state. | |
1086 | @item PRELIGHT | |
4a446de9 RS |
1087 | This is the state for a widget that can be manipulated, when the mouse |
1088 | pointer is over it---for example when the mouse is over the thumb in | |
1089 | the scroll bar or over a menu item. When the mouse is over a button | |
1090 | that is not pressed, the button is in this state. | |
488dd4c4 | 1091 | @item SELECTED |
4a446de9 RS |
1092 | This is the state for data that has been selected by the user. It can |
1093 | be selected text or items selected in a list. This state is not used | |
1094 | in Emacs. | |
488dd4c4 JD |
1095 | @item INSENSITIVE |
1096 | This is the state for widgets that are visible, but they can not be | |
10214524 RS |
1097 | manipulated in the usual way---for example, buttons that can't be |
1098 | pressed, and disabled menu items. To display disabled menu items in | |
1099 | yellow, use @code{fg[INSENSITIVE] = "yellow"}. | |
488dd4c4 JD |
1100 | @end table |
1101 | ||
10214524 | 1102 | Here are the things that can go in a style declaration: |
488dd4c4 JD |
1103 | |
1104 | @table @code | |
1105 | @item bg[@var{state}] = @var{color} | |
10214524 RS |
1106 | This specifies the background color for the widget. Note that |
1107 | editable text doesn't use @code{bg}; it uses @code{base} instead. | |
488dd4c4 JD |
1108 | |
1109 | @item base[@var{state}] = @var{color} | |
10214524 RS |
1110 | This specifies the background color for editable text. In Emacs, this |
1111 | color is used for the background of the text fields in the file | |
1112 | dialog. | |
488dd4c4 JD |
1113 | |
1114 | @item bg_pixmap[@var{state}] = "@var{pixmap}" | |
10214524 RS |
1115 | This specifies an image background (instead of a background color). |
1116 | @var{pixmap} should be the image file name. GTK can use a number of | |
1117 | image file formats, including XPM, XBM, GIF, JPEG and PNG. If you | |
1118 | want a widget to use the same image as its parent, use | |
1119 | @samp{<parent>}. If you don't want any image, use @samp{<none>}. | |
1120 | @samp{<none>} is the way to cancel a background image inherited from a | |
1121 | parent style. | |
1122 | ||
1123 | You can't specify the file by its absolute file name. GTK looks for | |
1124 | the pixmap file in directories specified in @code{pixmap_path}. | |
1125 | @code{pixmap_path} is a colon-separated list of directories within | |
1126 | double quotes, specified at the top level in a @file{gtkrc} file | |
1127 | (i.e. not inside a style definition; see example above): | |

1132 | ||
1133 | @item fg[@var{state}] = @var{color} | |
10214524 RS |
1134 | This specifies the foreground color for widgets to use. It is the |
1135 | color of text in menus and buttons, and the color for the arrows in | |
1136 | the scroll bar. For editable text, use @code{text}. | |
488dd4c4 JD |
1137 | |
1138 | @item text[@var{state}] = @var{color} | |
177c0ea7 | 1139 | This is the color for editable text. In Emacs, this color is used for the |
488dd4c4 JD |
1140 | text fields in the file dialog. |
1141 | ||
1142 | @item font_name = "@var{font}" | |
81c45292 | 1143 | This specifies the font for text in the widget. @var{font} is a |
10214524 RS |
1144 | Pango font name, for example @samp{Sans Italic 10}, @samp{Helvetica |
1145 | Bold 12}, @samp{Courier 14}, @samp{Times 18}. See below for exact | |
1146 | syntax. The names are case insensitive. | |
488dd4c4 JD |
1147 | @end table |
1148 | ||
10214524 RS |
1149 | There are three ways to specify a color: by name, in hexadecimal |
1150 | form, and with an RGB triplet. | |
488dd4c4 JD |
1151 | |
1152 | @noindent | |
1153 | A color name is written within double quotes, for example @code{"red"}. | |
1154 | ||
1155 | @noindent | |
10214524 RS |
1156 | Hexadecimal form is the same as in X: |
1157 | @code{#@var{rrrr}@var{gggg}@var{bbbb}}, where all three color specs | |
1158 | must have the same number of hex digits (1, 2, 3 or 4). | |
488dd4c4 JD |
1159 | |
1160 | @noindent | |
10214524 RS |
1161 | An RGB triplet looks like @code{@{ @var{r}, @var{g}, @var{b} @}}, |
1162 | where @var{r}, @var{g} and @var{b} are either integers in the range | |
1163 | 0-65535 or floats in the range 0.0-1.0. | |
488dd4c4 JD |
1164 | |
1165 | Pango font names have the form ``@var{family-list} @var{style-options} | |
5a7f4c1b | 1166 | @var{size}.'' |
488dd4c4 JD |
1167 | @cindex Pango font name |
1168 | @noindent | |
1169 | @var{family-list} is a comma separated list of font families optionally | |
1170 | terminated by a comma. This way you can specify several families and the | |
1171 | first one found will be used. @var{family} corresponds to the second part in | |
1172 | an X font name, for example in | |
1173 | ||
1174 | @smallexample | |
1175 | -adobe-times-medium-r-normal--12-120-75-75-p-64-iso10646-1 | |
1176 | @end smallexample | |
1177 | ||
1178 | @noindent | |
17f6554c | 1179 | the family name is @samp{times}. |
488dd4c4 JD |
1180 | |
1181 | @noindent | |
1182 | @var{style-options} is a whitespace separated list of words where each word | |
1183 | is a style, variant, weight, or stretch. The default value for all of | |
1184 | these is @code{normal}. | |
1185 | ||
1186 | @noindent | |
1187 | A `style' corresponds to the fourth part of an X font name. In X font | |
10214524 RS |
1188 | names it is the character @samp{r}, @samp{i} or @samp{o}; in Pango |
1189 | font names the corresponding values are @code{normal}, @code{italic}, | |
1190 | or @code{oblique}. | |
488dd4c4 JD |
1191 | |
1192 | @noindent | |
1193 | A `variant' is either @code{normal} or @code{small-caps}. | |
1194 | Small caps is a font with the lower case characters replaced by | |
1195 | smaller variants of the capital characters. | |
1196 | ||
1197 | @noindent | |
1198 | Weight describes the ``boldness'' of a font. It corresponds to the third | |
1199 | part of an X font name. It is one of @code{ultra-light}, @code{light}, | |
1200 | @code{normal}, @code{bold}, @code{ultra-bold}, or @code{heavy}. | |
1201 | ||
1202 | @noindent | |
1203 | Stretch gives the width of the font relative to other designs within a | |
1204 | family. It corresponds to the fifth part of an X font name. It is one of | |
1205 | @code{ultra-condensed}, @code{extra-condensed}, @code{condensed}, | |
