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.
