NAME
       xfontsel - point and click selection of X11 font names

SYNTAX
       xfontsel  [-toolkitoption  ...]	 [-pattern  fontname]  [-print] [-sample text] [-sample16
       text16] [-sampleUCS textUCS] [-scaled]

DESCRIPTION
       The xfontsel application provides a simple way to  display  the	fonts  known  to  your	X
       server, examine samples of each, and retrieve the X Logical Font Description ("XLFD") full
       name for a font.

       If -pattern is not specified, all fonts with XLFD 14-part names will  be  selectable.   To
       work  with  only  a subset of the fonts, specify -pattern followed by a partially or fully
       qualified font name; e.g., ``-pattern *medium*'' will select that subset  of  fonts  which
       contain	the  string  ``medium''  somewhere in their font name.	Be careful about escaping
       wildcard characters in your shell.

       If -print is specified on the command line the selected font specifier will be written  to
       standard  output  when  the quit button is activated.  Regardless of whether or not -print
       was specified, the font specifier may be made the PRIMARY (text) selection  by  activating
       the select button.

       The  -sample  option  specifies the sample text to be used to display the selected font if
       the font is linearly indexed, overriding the default.

       The -sample16 option specifies the sample text to be used to display the selected font  if
       the font is matrix encoded, overriding the default.

       The  -sampleUCS	option	specifies the sample text encoded in the UTF-8 form to be used to
       display the selected font if the font has a CHARSET_REGISTRY of ISO10646,  overriding  the
       default.

       The  -scaled option enables the ability to select scaled fonts at arbitrary pixel or point
       sizes.

INTERACTIONS
       Clicking any pointer button in one of the XLFD field names will pop up a menu of the  cur-
       rently-known possibilities for that field.  If previous choices of other fields were made,
       only values for fonts which matched the previously selected fields will be selectable;  to
       make  other values selectable, you must deselect some other field(s) by choosing the ``*''
       entry in that field.  Unselectable values may be omitted from the menu entirely as a  con-
       figuration  option; see the ShowUnselectable resource, below.  Whenever any change is made
       to a field value, xfontsel will assert ownership of  the  PRIMARY_FONT  selection.   Other
       applications (see, e.g., xterm) may then retrieve the selected font specification.

       Scalable  fonts	come  back  from the server with zero for the pixel size, point size, and
       average width fields.  Selecting a font name with a zero in these positions results in  an
       implementation-dependent  size.	Any pixel or point size can be selected to scale the font
       to a particular size.  Any average width can be selected to anamorphically scale the  font
       (although you may find this challenging given the size of the average width menu).

       Clicking  the  left  pointer button in the select widget will cause the currently selected
       font name to become the PRIMARY text selection as  well	as  the  PRIMARY_FONT  selection.
       This  then  allows  you	to  paste  the string into other applications.	The select button
       remains highlighted to remind you of this fact, and de-highlights when some other applica-
       tion takes the PRIMARY selection away.  The select widget is a toggle; pressing it when it
       is highlighted will cause xfontsel to release the selection ownership and de-highlight the
       widget.	 Activating  the select widget twice is the only way to cause xfontsel to release
       the PRIMARY_FONT selection.

RESOURCES
       The application class is XFontSel.  Most of the user-interface is configured in	the  app-
       defaults  file; if this file is missing a warning message will be printed to standard out-
       put and the resulting window will be nearly incomprehensible.

       Most  of  the  significant   parts   of	 the   widget	hierarchy   are   documented   in
       /usr/share/X11/app-defaults/XFontSel,

       Application specific resources:

       cursor (class Cursor)
	       Specifies the cursor for the application window.

       pattern (class Pattern)
	       Specifies the font name pattern for selecting a subset of available fonts.  Equiv-
	       alent to the -pattern option.  Most useful patterns  will  contain  at  least  one
	       field delimiter; e.g. ``*-m-*'' for monospaced fonts.

       pixelSizeList (class PixelSizeList)
	       Specifies  a  list  of pixel sizes to add to the pixel size menu, so that scalable
	       fonts can be selected at those pixel sizes.  The default pixelSizeList contains 7,
	       30, 40, 50, and 60.

       pointSizeList (class PointSizeList)
	       Specifies a list of point sizes (in units of tenths of points) to add to the point
	       size menu, so that scalable fonts can be  selected  at  those  point  sizes.   The
	       default pointSizeList contains 250, 300, 350, and 400.

       printOnQuit (class PrintOnQuit)
	       If  True  the  currently selected font name is printed to standard output when the
	       quit button is activated.  Equivalent to the -print option.

       sampleText (class Text)
	       The sample 1-byte text to use for linearly indexed fonts.  Each glyph index  is	a
	       single byte, with newline separating lines.

       sampleText16 (class Text16)
	       The  sample  2-byte text to use for matrix-encoded fonts.  Each glyph index is two
	       bytes, with a 1-byte newline separating lines.

       scaledFonts (class ScaledFonts)
	       If True then selection of arbitrary pixel and point sizes for  scalable	fonts  is
	       enabled.

       Widget specific resources:

       showUnselectable (class ShowUnselectable)
	       Specifies,  for	each  field menu, whether or not to show values that are not cur-
	       rently selectable, based upon previous field  selections.   If  shown,  the  unse-
	       lectable  values  are  clearly  identified  as  such and do not highlight when the
	       pointer	is  moved  down  the  menu.   The  full  name	of   this   resource   is
	       fieldN.menu.options.showUnselectable, class MenuButton.SimpleMenu.Options.ShowUns-
	       electable; where N is replaced with the field number (starting with the	left-most
	       field  numbered	0).   The  default is True for all but field 11 (average width of
	       characters in font) and False for field 11.  If you never want to see unselectable
	       entries,  '*menu.options.showUnselectable:False'  is a reasonable thing to specify
	       in a resource file.

BUGS
       Sufficiently ambiguous patterns can be misinterpreted and lead  to  an  initial	selection
       string  which may not correspond to what the user intended and which may cause the initial
       sample text output to fail to match the proffered string.  Selecting any new  field  value
       will correct the sample output, though possibly resulting in no matching font.

       Should be able to return a FONT for the PRIMARY selection, not just a STRING.

       Any  change  in	a field value will cause xfontsel to assert ownership of the PRIMARY_FONT
       selection.  Perhaps this should be parameterized.

       When running on a slow machine, it is possible for the user to request a field menu before
       the font names have been completely parsed.  An error message indicating a missing menu is
       printed to stderr but otherwise nothing bad (or good) happens.

       The average-width menu is too large to be useful.
