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.
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.
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 should 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.
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.
XClock xclock
Clock clock
- DISPLAY
- to get the default host and display number.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
- /usr/X11R6/lib/X11/app-defaults/XClock
- Specifies required resources
