Lucid Menu X Resources
If the Emacs installed at your site was built to use the X toolkit with the Lucid menu widgets, then the menu bar is a separate widget and has its own resources. The resource names contain pane.menubar (following, as always, the name of the Emacs invocation, or Emacs, which stands for all Emacs invocations). Specify them like this:
Emacs.pane.menubar.resource: value
For example, to specify the font 8x16 for the menu-bar items, write this:
Emacs.pane.menubar.font: 8x16
Resources for non-menubar toolkit pop-up menus have menu*, in like fashion. For example, to specify the font 8x16 for the pop-up menu items, write this:
Emacs.menu*.font: 8x16
For dialog boxes, use dialog instead of menu:
Emacs.dialog*.font: 8x16
Experience shows that on some systems you may need to add shell. before the pane.menubar or menu*. On some other systems, you must not add shell..
Here is a list of the specific resources for menu bars and pop-up menus:
- font
Font for menu item text. - foreground
Color of the foreground. - background
Color of the background. - buttonForeground
In the menu bar, the color of the foreground for a selected item. - horizontalSpacing
Horizontal spacing in pixels between items. Default is 3. - verticalSpacing
Vertical spacing in pixels between items. Default is 1. - arrowSpacing
Horizontal spacing between the arrow (which indicates a submenu) and the associated text. Default is 10. - shadowThickness
Thickness of shadow line around the widget. - margin
The margin of the menu bar, in characters. The default of 4 makes the menu bar appear like the LessTif/Motif one.
