DESCRIPTION
The xarclock program displays the time in analog or digital, reverse or
normal form. The time is continuously updated at a frequency which may
be specified by the user. This program is based on the program
xlock(1) that is distributed together with the X11 release and is
nothing more than a wrapper around the Athena Clock widget.
This program is an extension of the standard X clock widget. New
features are: Configurable direction of rotation and font support in
analog mode.
OPTIONS
Xarclock accepts all of the standard X Toolkit command line options
along with the additional options listed below:
-roman This option specifies that roman digits should be used on an
analog clock.
-arabic
This option specifies that arabic digits should be used on an
analog clock. This is the default
-south This option specifies the direction the clock will turn, on the
southern half of the earth the 3, early afternoon, is on the
left side. This is the default.
-north This option specifies that the clock will behave like xclock(1).
-analog
This option indicates that a conventional 12 hour clock face
with tick marks and hands should be used. This is the default.
-digital (or -d)
This option indicates that a 24 hour digital clock should be
used.
-chime This option indicates that the clock should chime once on the
half hour and twice on the hour.
-hd color (or -hands color)
This option specifies the color of the hands on an analog clock.
The default is black.
-hl color (or -highlight color)
This option specifies the color of the edges of the hands on an
analog clock, and is only useful on color displays. The default
is black.
-fn fontname
This option sets the name of the used fonts on the analog clock
to fontname.
-help This option indicates that a brief summary of the allowed
options should be printed on the standard error.
-padding pixels
This option specifies the width in pixels of the padding between
the window border and clock text or picture. The default is 10
on a digital clock and 8 on an analog clock.
-update seconds
This option specifies the frequency in seconds at which xclock
should update its display. If the clock is obscured and then
exposed, it will be updated immediately. A value of less than
30 seconds will enable a second hand on an analog clock. The
default is 60 seconds.
X DEFAULTS
This program uses the Athena Clock widget. It understands all of the
core resource names and classes as well as:
width (class Width)
Specifies the width of the clock. The default for analog clocks
is 164 pixels; the default for digital clocks is whatever is
needed to hold the clock when displayed in the chosen font.
height (class Height)
Specifies the height of the clock. The default for analog
clocks is 164 pixels; the default for digital clocks is whatever
is needed to hold the clock when displayed in the chosen font.
update (class Interval)
Specifies the frequency in seconds at which the time should be
redisplayed.
foreground (class Foreground)
Specifies the color for the tic marks. The default is depends on
whether reverseVideo is specified. If reverseVideo is specified
the default is lwhite, otherwise the default is black.
hands (class Foreground)
Specifies the color of the insides of the clock’s hands. The
default is depends on whether reverseVideo is specified. If
reverseVideo is specified the default is lwhite, otherwise the
default is black.
highlight (class Foreground)
Specifies the color used to highlight the clock’s hands. The
default is
depends on whether reverseVideo is specified. If reverseVideo
is specified the default is lwhite, otherwise the default is
black.
analog (class Boolean)
Specifies whether or not an analog clock should be used instead
of a digital one. The default is True.
roman (class Boolean)
Specifies whether roman or arabic digits shoud be used on the
analog clock. The default is True.
north (class Boolean)
Specifies whether or not reverse direction of rotation of hands
of the analog clock should be used. The default is False.
chime (class Boolean)
Specifies whether or not a bell should be rung on the hour and
half hour.
padding (class Margin)
Specifies the amount of internal padding in pixels to be used.
The default is 8.
font (class Font)
Specifies the font to be used for the digital clock. Note that
variable width fonts currently will not always display
correctly.
WIDGETS
In order to specify resources, it is useful to know the hierarchy of
the widgets which compose xclock. In the notation below, indentation
indicates hierarchical structure. The widget class name is given
first, followed by the widget instance name.
