If Emacs is compiled with the X toolkit support using Motif or LessTif widgets, you can use X resources to customize the appearance of the menu bar (Menu Bar), pop-up menus, and dialog boxes (Dialog Boxes). However, the resources are organized differently from Lucid widgets. The resource names for the menu bar are in the pane.menubar class, and they must be specified in this form:

Emacs.pane.menubar.@var{subwidget}.@var{resource}: @var{value}

@noindent For pop-up menus, the resources are in the menu* class, instead of pane.menubar. For dialog boxes, they are in dialog. In each case, each individual menu string is a subwidget; the subwidget's name is the same as the menu item string. For example, the File menu in the menu bar is a subwidget named emacs.pane.menubar.File. Typically, you want to specify the same resources for the whole menu bar. To do this, use * instead of a specific subwidget name. For example, to specify the font 8x16 for all menu bar items, including submenus, write this:

Emacs.pane.menubar.*.fontList: 8x16

Each item in a submenu also has its own name for X resources; for example, the File submenu has an item named Save (current buffer). A resource specification for a submenu item looks like this:

Emacs.pane.menubar.popup_*.@var{menu}.@var{item}.@var{resource}: @var{value}

@noindent For example, here's how to specify the font for the Save (current buffer) item:

Emacs.pane.menubar.popup_*.File.Save (current buffer).fontList: 8x16

@noindent For an item in a second-level submenu, such as Complete Word under Spell Checking under Tools, the resource fits this template:

Emacs.pane.menubar.popup_*.popup_*.@var{menu}.@var{resource}: @var{value}

@noindent For example,

Emacs.pane.menubar.popup_*.popup_*.Spell Checking.Complete Word: @var{value}

@noindent (This should be one long line.) If you want the submenu items to look different from the menu bar itself, you must first specify the resource for all of them, then override the value for submenus alone. Here is an example:

Emacs.pane.menubar.*.fontList: 9x18
Emacs.pane.menubar.popup_*.fontList: 8x16

To specify resources for the LessTif file-selection box, use fsb*, like this:

Emacs.fsb*.fontList: 8x16

Here is a list of resources for LessTif menu bars and pop-up menus:

armColor

Amount of space to leave around the item, within the border.

borderWidth

The width of the border around the menu item, on all sides.

shadowThickness

The width of the border shadow.

bottomShadowColor

The color for the border shadow, on the bottom and the right.

topShadowColor
