Standard Interface Fonts

Default Font Names

The set of standard interface font names is defined by the XLFD field name values described in Table 2-2.

Table 2-1 Field Name Values for Standard Interface Font Names

Field	Value	Description
FOUNDRY	dt	CDE name
FAMILY_NAME	interface system or interface user	CDE standard interface font name
WEIGHT_NAME	medium or bold	Weight of the font
SLANT	r	Roman
SET_WIDTH	normal	Normal set width
SPACING	p or m
ADD_STYLE	size hint  sans or serif	Proportional or Monospace values from xxs to xxl  Sans for sans serif font or serif for serif
PIXEL_SIZE	Platform dependent
POINT_SIZE	Platform dependent
RESOLUTION_X	Platform dependent
RESOLUTION_Y	Platform dependent
AVERAGE_WIDTH	m p	Monospace for user font  Proportional for system font
NUMERIC FIELD	Platform dependent
CHAR_SET_REGISTRY	Locale Dependent
ENCODING	Locale Dependent

Point Sizes for Standard Interface Fonts

The seven named point sizes for each of the three styles are prepend in the ADD_STYLE_NAME field. The font XLFD patterns matching these names can match a named size, not a numeric size. These named sizes are used because the exact size of an interface font is less important than its nominal size, and implementation differences for the hand-tuned interface fonts do not allow common numeric point sizes to be assured across systems.

The seven nominal sizes are as follows:

xxs	extra extra small
xs	extra small
s	small
m	medium
l	large
xl	extra large
xxl	extra extra large

The goal of these named sizes is to provide enough fonts to display a variety monitor sizes and resolutions that CDE will run on, and the range of user preferences for comfortably reading button labels, window titles and so forth, can be accommodated in the GUI. Both the smallest size, xxs, and the largest size, xxl, are meant to be reasonable sizes for displaying and viewing the CDE desktop on common displays and X terminals; they are not meant to imply either hard-to-read fine print or headline-sized display type.

Patterns for the Standard Interface Font Names

Using these values, the XLFD pattern

-dt-interface*-*

logically matches the full set of XCDE Standard Interface Font Names. (Note that no specific X server behavior is implied).

For example, in Western locales, the full set of 21 CDE Standard Interface Font Names can be represented:

-dt-interface system-medium-r-normal-*-*-*-*-*-*-*-iso8859-1
-dt-interface user-medium-r-normal-*-*-*-*-*-m-*-iso8859-1
-dt-interface user-bold-r-normal-*-*-*-*-*-m-*-iso8859-1

The full set of patterns in the app-defaults files for all seven system font sizes is:

-dt-interface system-medium-r-normal-xxs*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-xs*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-s*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-m*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-l*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-xl*-*-*-*-*-*-*-iso8859-1
-dt-interface system-medium-r-normal-xxl*-*-*-*-*-*-*-iso8859-1

These patterns could be used in a resource file and will match the full CDE Standard Interface Names for the iso Latin-1 locales on all CDE-compliant systems. For more information, see the DtStdInterfaceFontNames(5) man page.
