Using the Style Manager Font dialog box, you can select the font group and size you want for all applications. You can also specify fonts on the command line or use resources to:
Set font resources for individual applications
Assign different fonts to be used by the Font dialog box
A font is a type style in which text characters are printed or displayed. The desktop includes a variety of fonts in different styles and sizes.
A bitmap font is made from a matrix of dots. (By default, Style Manager configures bitmap fonts only.) The font is completely contained in one file. Many files are needed to have a complete range of sizes, slants, and weights.
Fonts are specified as values of resources and as parameters to commands. The X Logical Font Description (XLFD) name is the method by which a desired font is requested. The system finds the font that best matches the description it was given.
The Style Manager Font dialog box enables you to select fonts (up to seven sizes) for things such as text entry and labels. It also enables you to add or delete font groups.
When a font is selected, the following resources are written to the RESOURCE_MANAGER property:
SystemFont is used for system areas, such as menu bars, menu panes, push buttons, toggle buttons, and labels. The following resource is set by SystemFont:
*FontList
--displayed in system areas of desktop clients and other clients created using the OSF/Motif toolkit.
UserFont is used for text entered into windows. The following resources are set by UserFont:
*Font
--supports earlier versions of X applications
*FontSet
--the primary setting
*XmText*FontList
--displayed in text entry boxes
*XmTextField*FontList
--displayed in text entry boxes
The fonts used for each selection in the Font dialog box are specified in the /usr/dt/app-defaults/Dtstyle resource file. Up to seven sizes can be specified.
NumFonts
--number of font sizes in the Font dialog box
SystemFont[1-7]
--up to seven resources assigning a specific font to a Font dialog box selection for SystemFont
UserFont[1-7]
--up to seven resources assigning a specific font to a Font dialog box selection for UserFont
The default fonts for these resources have been chosen for readability on various displays. If you want a specific font for an application, set the font with an application font resource rather than changing these desktop fonts.
For more information about application fonts, seethe DtStdAppFontNames(5) and DtStdInterfaceFontNames(5) man pages.
Type the following:
xlsfonts [-options] [-fn pattern]
A list of XLFD names and font alias names available on your system is displayed. Bitmap fonts show values in all fourteen XLFD fields. Scalable typefaces show zeros in the PixelSize, PointSize, ResolutionX, and ResolutionY positions.
To check for specific fonts, use the pattern-matching capability of xlsfonts. Use wildcards to replace the part of the pattern you are not trying to match.
If xlsfonts does not show any font names starting with dt, your font path does not include the desktop fonts. Type the following command to include the desktop fonts into your available fonts:
xset +fp directory name
where directory name is the directory containing the desktop fonts. The default location set by session startup is /usr/dt/config/xfonts/language.
For additional information:
The xset and xlsfonts man pages list the available options.
Using the X Window System explains font alias names and the xset client.
Use the -xrm command-line option to specify a font resource for a specific client. For example:
application name -xrm "*bitstream-charter-medium-r-normal-8-88-75-75-p-45-iso8859-1"
A font is specified by listing fourteen different characteristics, separated by dashes (-). This is called the X Logical Font Description (XLFD). In some cases, a property in the list can be replaced by a * wildcard, and a character within a property can be replaced by a ? wildcard. Table 17-4 lists font property string specifications.
The form of the property string specification is:
"-Foundry-FamilyName-WeightName- Slant-SetwidthName-AddStyleName-PixelSize- PointSize-ResolutionX-ResolutionY-Spacing- AverageWidth-CharSetRegistry-CharSetCoding"
Table 17-4 Font Property String Specification
Property String |
Definition |
---|---|
Foundry |
A string identifying the font designer |
FamilyName |
A string identifying the trademarked name of the font |
WeightName |
A string giving the relative weight of the font, such as bold |
Slant |
A code describing the direction of slant: R (Roman-no slant) I (Italic-slant right) O (Oblique-slant right) RI (Reverse Italic-slant left) RO (Reverse Oblique-slant left) |
SetwidthName |
A string describing the width, such as compressed or expanded |
AddStyleName |
A string providing any additional information needed to uniquely identify the font |
PixelSize |
An integer giving the size of an em-square in pixels |
PointSize |
An integer giving the size of an em-square in decipoints |
ResolutionX |
An integer giving the horizontal resolution in pixels |
ResolutionY |
An integer giving the vertical resolution in pixels |
Spacing |
A code specifying the spacing between units: M (Monospace--fixed pitch) P (Proportional space--variable pitch) C (Character cell) |
AverageWidth |
An integer giving the average width in 1/10th pixels |
CharSetRegistry |
A string identifying the registration authority that has registered the font encoding |
CharSetEncoding |
A string identifying the character set in the specified registry |
The following XLFD name describes a font named charter made by Bitstream that supports the ISO8859-1 standard encoding:
-bitstream-charter-medium-r-normal--8-80-75-75-p-45-iso8859-1
It is medium weight, with no special slanting, and normal width. The font is proportional, with an em-square box of 8 pixels or 8.0 points. The horizontal and vertical resolution are both 75 pixels. The average width of a character is 45 1/10ths pixels or 4.5 pixels.
Parts of this string can be replaced by wildcards. The system uses the first font it finds that matches the parts you have specified.
If all you want is an eight-pixel charter font, you could use:
*-charter-*-*-*-*-8-*
By selecting the Attributes button from the Style Manager Font dialog box, you can view the following font group attributes:
Font Group
Size
Alias
Alias XLFD
Alias Location
Font
Font XLFD
When a user adds a font group, it is stored in the following location:
HomeDirectory/.dt/sdtfonts/host/locale/typeface-nnnnnn
host is the local workstation's host name.
locale is the user's current locale such as "C" or "ja."
typeface-nnnnnn is a name drived from the selected font and a unique generated number.
This font group directory cotains the following three files
fonts.alias
fonts.dir
sdtfonts.group
The fonts.alias and fonts.dir files are the normal X11 font files suitable for adding to the Xerver's font path. The sdtfonts.group file contains the user specified font group name.
So that other users can access the font groups on a workstation, the system administrator can copy font groups to the /etc/dt/sdtfonts/locale directory or to the /usr/openwin/lib/X11/stdfonts/locale directory. Session Manager first looks in HomeDirectory/.dt/stdfonts/host/locale, next in /etc/dt/sdtfonts/locale, and last in /usr/openwin/lib/X11/stdfonts/locale.
