On MS-Windows, you +can customize some of the same aspects using the system registry. +@xref{MS-Windows Registry}. Likewise, Emacs on MacOS Carbon emulates X +resources using the Preferences system. @xref{Mac Environment Variables}. + + When Emacs is built using an ``X toolkit'', such as Lucid or +LessTif, you need to use X resources to customize the appearance of +the widgets, including the menu-bar, scroll-bar, and dialog boxes. +This is because the libraries that implement these don't provide for +customization through Emacs. GTK+ widgets use a separate system of +``GTK resources''. In this chapter we describe the most commonly used +resource specifications. For full documentation, see the online +manual. + +@c Add xref for LessTif/Motif menu resources. + +@menu +* Resources:: Using X resources with Emacs (in general). +* Table of Resources:: Table of specific X resources that affect Emacs. +* Face Resources:: X resources for customizing faces. +* Lucid Resources:: X resources for Lucid menus. +* GTK resources:: Resources for GTK widgets. +@end menu + +@node Resources +@appendixsec X Resources +@cindex resources +@cindex X resources +@cindex @file{~/.Xdefaults} file +@cindex @file{~/.Xresources} file + + Programs running under the X Window System organize their user +options under a hierarchy of classes and resources. You can specify +default values for these options in your X resources file, usually +named @file{~/.Xdefaults} or @file{~/.Xresources}. +If changes in @file{~/.Xdefaults} do not +take effect, it is because your X server stores its own list of +resources; to update them, use the shell command @command{xrdb}---for +instance, @samp{xrdb ~/.Xdefaults}. + + Each line in the file specifies a value for one option or for a +collection of related options, for one program or for several programs +(optionally even for all programs). + +@cindex Registry (MS-Windows) + MS-Windows systems don't support @file{~/.Xdefaults} files, but +Emacs compiled for Windows looks for X resources in the Windows +Registry, under the key @samp{HKEY_CURRENT_USER\SOFTWARE\GNU\Emacs} +and then under the key @samp{HKEY_LOCAL_MACHINE\SOFTWARE\GNU\Emacs}. +The menu and scrollbars are native widgets on MS-Windows, so they are +only customizable via the system-wide settings in the Display Control +Panel. You can also set resources using the @samp{-xrm} command line +option (see below.) + + Applications such as Emacs look for resources with specific names +and their particular meanings. Case distinctions are significant in +these names. Each resource specification in @file{~/.Xdefaults} +states the name of the program and the name of the resource. For +Emacs, the program name is @samp{Emacs}. It looks like this: + +@example +Emacs.borderWidth: 2 +@end example + + The order in which the lines appear in the file does not matter. +Also, command-line options always override the X resources file. + + You can experiment with the effect of different resource settings +with the @code{editres} program. Select @samp{Get Tree} from the +@samp{Commands} menu, then click on an Emacs frame. This will display +a tree showing the structure of X toolkit widgets used in an Emacs +frame. Select one of them, such as @samp{menubar}, then select +@samp{Show Resource Box} from the @samp{Commands} menu. This displays +a list of all the meaningful X resources for that widget, and allows +you to edit them. Changes take effect when you click on the +@samp{Apply} button. (See the @code{editres} man page for more +details.) + +@node Table of Resources +@appendixsec Table of X Resources for Emacs + + This table lists the resource names that designate options for +Emacs, not counting those for the appearance of the menu bar, each +with the class that it belongs to: + +@table @asis +@item @code{background} (class @code{Background}) +Background color name. + +@item @code{borderColor} (class @code{BorderColor}) +Color name for the external border. + +@item @code{cursorColor} (class @code{Foreground}) +Color name for text cursor (point). + +@item @code{font} (class @code{Font}) +Font name (or fontset name, @pxref{Fontsets}) for @code{default} font. + +@item @code{foreground} (class @code{Foreground}) +Color name for text. + +@item @code{geometry} (class @code{Geometry}) +Window size and position. Be careful not to specify this resource as +@samp{emacs*geometry}, because that may affect individual menus as well +as the Emacs frame itself. + +If this resource specifies a position, that position applies only to the +initial Emacs frame (or, in the case of a resource for a specific frame +name, only that frame).

For example, to specify +the font @samp{8x16} for the pop-up menu items, write this: + +@example +Emacs.menu*.font: 8x16 +@end example + +@noindent +For dialog boxes, use @samp{dialog*}: + +@example +Emacs.dialog*.font: 8x16 +@end example + +@noindent +The Lucid menus can display multilingual text in your locale. For +more information about fontsets see the man page for +@code{XCreateFontSet}. To enable multilingual menu text you specify a +@code{fontSet} resource instead of the font resource. If both +@code{font} and @code{fontSet} resources are specified, the +@code{fontSet} resource is used. + + Thus, to specify @samp{-*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,*} +for both the popup and menu bar menus, write this: + +@example +Emacs*menu*fontSet: -*-helvetica-medium-r-*--*-120-*-*-*-*-*-*,* +@end example + +@noindent +The @samp{*menu*} as a wildcard matches @samp{pane.menubar} and +@samp{menu@dots{}}. + + Experience shows that on some systems you may need to add +@samp{shell.}@: before the @samp{pane.menubar} or @samp{menu*}. On +some other systems, you must not add @samp{shell.}.
