.SH DESCRIPTION
|
|
.PP
|
|
The \fIxfontsel\fP 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.
|
|
.PP
|
|
If \fB-pattern\fP is not specified, all fonts with XLFD 14-part
|
|
names will be selectable. To work with only a subset of the
|
|
fonts, specify \fB-pattern\fP 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.
|
|
.PP
|
|
If \fB-print\fP is specified on the command line the selected
|
|
font specifier will be written to standard output when the \fIquit\fP
|
|
button is activated. Regardless of whether or not \fB-print\fP was
|
|
specified, the font specifier may be made the PRIMARY (text)
|
|
selection by activating the \fIselect\fP button.
|
|
.PP
|
|
The \fB-sample\fP option specifies the sample text to be used to
|
|
display the selected font if the font is linearly indexed,
|
|
overriding the default.
|
|
.PP
|
|
The \fB-sample16\fP option specifies the sample text to be used to
|
|
display the selected font if the font is matrix encoded,
|
|
overriding the default.
|
|
.PP
|
|
The \fB-sampleUCS\fP 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.
|
|
.PP
|
|
The \fB-scaled\fP option enables the ability to select scaled fonts
|
|
at arbitrary pixel or point sizes.
|
|
.PP
|
|
.SH INTERACTIONS
|
|
.PP
|
|
Clicking any pointer button in one of the XLFD field names will pop up
|
|
a menu of the currently-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 configuration option; see the \fBShowUnselectable\fP resource, below.
|
|
Whenever any change is made to a field value, \fIxfontsel\fP will
|
|
assert ownership of the PRIMARY_FONT selection. Other applications
|
|
(see, e.g., \fIxterm\fP) may then retrieve the selected font specification.
|
|
.PP
|
|
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).
|
|
.PP
|
|
Clicking the left pointer button in the \fIselect\fP 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 \fBselect\fP button remains
|
|
highlighted to remind you of this fact, and de-highlights when
|
|
some other application takes the PRIMARY selection away. The
|
|
\fIselect\fP widget is a toggle; pressing it when it is highlighted
|
|
will cause \fIxfontsel\fP to release the selection ownership and
|
|
de-highlight the widget. Activating the \fIselect\fP widget twice
|
|
is the only way to cause \fIxfontsel\fP to release the
|
|
PRIMARY_FONT selection.

.SH RESOURCES
|
|
.PP
|
|
The application class is \fBXFontSel\fP. 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 output and the
|
|
resulting window will be nearly incomprehensible.
|
|
.PP
|
|
Most of the significant parts of the widget hierarchy are documented
|
|
in
|
|
.IR __apploaddir__/XFontSel ,
|
|
.PP
|
|
Application specific resources:
|
|
.PP
|
|
.TP 8
|
|
.B "cursor (\fPclass\fB Cursor)"
|
|
Specifies the cursor for the application window.
|
|
.TP 8
|
|
.B "pattern (\fPclass\fB Pattern)"
|
|
Specifies the font name pattern for selecting a subset of
|
|
available fonts. Equivalent to the \fB-pattern\fP option.
|
|
Most useful patterns will contain at least one field
|
|
delimiter; e.g. ``*-m-*'' for monospaced fonts.
|
|
.TP 8
|
|
.B "pixelSizeList (\fPclass\fB 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.
|
|
.TP 8
|
|
.B "pointSizeList (\fPclass\fB 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.
|
|
.TP 8
|
|
.B "printOnQuit (\fPclass\fB PrintOnQuit)"
|
|
If \fITrue\fP the currently selected font name is printed
|
|
to standard output when the quit button is activated.
|
|
Equivalent to the \fB-print\fP option.
|
|
.TP 8
|
|
.B "sampleText (\fPclass\fB Text)"
|
|
The sample 1-byte text to use for linearly indexed fonts.
|
|
Each glyph index is a single byte, with newline separating lines.
|
|
.TP 8
|
|
.B "sampleText16 (\fPclass\fB 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.
|
|
.TP 8
|
|
.B "scaledFonts (\fPclass\fB ScaledFonts)"
|
|
If \fITrue\fP then selection of arbitrary pixel and point sizes for
|
|
scalable fonts is enabled.
|
|
.PP
|
|
Widget specific resources:
|
|
.PP
|
|
.TP 8
|
|
.B "showUnselectable (\fPclass\fB ShowUnselectable)"
|
|
Specifies, for each field menu, whether or not to show values that
|
|
are not currently selectable, based upon previous field selections.
|
|
If shown, the unselectable 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 \fBfieldN.menu.options.showUnselectable\fP,
|
|
class \fBMenuButton.SimpleMenu.Options.ShowUnselectable\fP;
|
|
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.

.SH BUGS
|
|
.PP
|
|
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.
|
|
.PP
|
|
Should be able to return a FONT for the PRIMARY selection, not
|
|
just a STRING.
|
|
.PP
|
|
Any change in a field value will cause \fIxfontsel\fP to assert
|
|
ownership of the PRIMARY_FONT selection. Perhaps this should
|
|
be parameterized.
|
|
.PP
|
|
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.
|
|
.PP
|
|
The average-width menu is too large to be useful.
