NAME

       XmFontList — Data type for a font list "XmFontList" "data types" "XmFontList"

SYNOPSIS

       #include <Xm/Xm.h>

DESCRIPTION

       XmFontList  is  the  data  type  for  a  font list. A font list consists of font list entries. Each entry
       contains a font or a font set (a group of fonts) and is identified with a tag, which is optional. If this
       tag is NULL, the tag is set to XmFONTLIST_DEFAULT_TAG.

       The value of XmFONTLIST_DEFAULT_TAG is XmFONTLIST_DEFAULT_TAG_STRING.

       When a compound string is displayed, the font list element tag of the compound string segment is  matched
       with  a  font  list  entry  tag  in the font list and the matching font list entry is used to display the
       compound string. A font list entry is chosen as follows:

          •  The first font list entry whose tag matches the tag of the compound string segment is used.

          •  If no match has been found and if the tag of the compound string segment is XmFONTLIST_DEFAULT_TAG,
             the first font list entry whose tag matches the tag that would result from creating an  entry  with
             XmSTRING_DEFAULT_CHARSET  is used.  For example, if creating an entry with XmSTRING_DEFAULT_CHARSET
             would result in the tag ISO8859-1, the compound string segment tag  XmFONTLIST_DEFAULT_TAG  matches
             the font list entry tag ISO8859-1.

          •  If no match has been found and if the tag of the compound string segment matches the tag that would
             result  from  creating a segment with XmSTRING_DEFAULT_CHARSET, the first font list entry whose tag
             is XmFONTLIST_DEFAULT_TAG is used.

          •  If no match has been found, the first entry in the font list is used.

       The font list interface consists of the routines listed in Related Information.

       Font lists are specified in resource files with the following syntax:

       resource_spec:  font_entry [, font_entry ]+

       The resource value string consists of one or more font list entries separated by commas. Each  font_entry
       identifies  a  font  or  font  set and an optional font list entry tag. A tag specified for a single font
       follows the font name and is separated by = (equals sign); otherwise, in a font set the tag is  separated
       by  a  colon.  The  colon  is required whether a tag is specified or not. A font entry uses the following
       syntax to specify a single font:

       font_name [ '=' tag ]

       For example, the following entry specifies a 10 point Times Italic font without a font list entry tag;

       *fontList:  -Adobe-Times-Medium-I-Normal--10*

       A font entry containing a font set is similar, except a semicolon separates multiple font names  and  the
       specification ends with a colon followed by an optional tag:

       font_name [ ';' font_name ]+ ':' [ tag ]

       A  font_name  is  an  X  Logical  Font  Description  (XLFD)  string and tag is any set of characters from
       ISO646IRV except space, comma, colon, equal sign and semicolon. Following is an example  of  a  font  set
       entry. It consists of three fonts (except for charsets), and an explicit font list entry tag.

       *fontList: -Adobe-Courier-Bold-R-Normal--25-180-100-100-M-150;-JIS-Fixed-Medium-R-Normal--26-180-100-100-C-240;-JIS-Fixed-Medium-R-Normal--26-180-100-100-C-120:MY_TAG

       Note  that  the  XmRenderTable  is  another  data  type  that  can  be  used for font lists. Refer to the
       XmRenderTable(3) for details.
