dclock(X) 19 June 1992 dclock(X) Name dclock - digital clock for X Syntax dclock [toolkitoption ...] [-option ...] Description The dclock program displays the time in digital format only. The time is updated on a per second basis or on a per minute basis. This program is nothing more than a wrapper around the dclock widget not associated with any particular widget set. When the clock is running, the user may change attributes by typing: r Toggles Reverse Video. s Toggles the seconds display. b Toggles the bell attribute. j Toggles the jump/scroll attribute. d Toggles the date format. m Toggles the military time format. a Toggles the alarm clock. q quit the program. Mouse button 3 puts the clock in the mode where the alarm clock can be set. The alarm must be set in 24-hour format to distinguish between am and pm time. Digits can be changed by selecting the digit with mouse button 1 or 2. Mouse button 1 advances the time and mouse button 2 moves the time backwards. Using mouse button 1 or 2 over the text at the bot- tom of the clock toggles the alarm from actually being set (or, use the ``a'' key). Options dclock accepts all of the standard X Toolkit command line options along with the additional options listed below: -help This option indicates that a brief summary of the allowed options should be printed on the standard error. -bell This option indicates that the beel will beep once on the half hour and twice on the hour. -miltime This option causes the clock to display the time in 24 hour (military) time format. -scroll -noscroll next digit. Since this is on by default, the -noscroll option can turn it off. -date format The date is printed under the time in the specified font. The string displayed is in the format argument. If the string con- tains a formatting character (%), then the next character is examined and a value is inserted into the string. Example: dclock -date "Today is %W" The date string will print Today is Friday if the weekday name happens to be friday. The formatting characters that are understood are: %W Full weekday name %w Three-char weekday name (Sun, Mon, Tue...) %M Full month name %m Three-char abbreviation for that month (Jan, Feb, Mar...) %d The date (numerical day number of the month) %Y Full year (4 digits) %y 2-digit year number -alarm -noalarm The alarm is turned on or off. Alarm rings bell and toggles the reverse video five times. -alarmTime HH:MM If alarm is set, it goes off at time specified in 24-hour for- mat. -seconds This option will update the clock every second and display the time including the seconds. -bg color This option specifies the color to use for the background of the window. The default is ``white.'' -bd color This option specifies the color to use for the border of the window. The default is ``black.'' -bw number This option specifies the width in pixels of the border sur- rounding the window. -fg color This option specifies the color to use for displaying text. The default is ``black.'' -fn font This option specifies the font to be used for displaying normal text. The default is ``Fixed.'' -rv This option indicates that reverse video should be simulated by swapping the foreground and background colors. -geometry geometry This option specifies the preferred size and position of the clock window. -display host:display This option specifies the X server to contact. -xrm resourcestring This option specifies a resource string to be used. This is especially useful for setting resources that do not have separate command line options. X defaults It understands all of the core resource names and classes as well as: width (class Width) Specifies the width of the clock. height (class Height) Specifies the height of the clock. foreground (class Foreground) Specifies the color for the tic marks. Using the class speci- fies the color for all things that normally would appear in the foreground color. The default is ``black'' because the core default for background is ``white.'' bell (class Boolean) Specifies whether or not a bell should be rung on the hour and half hour. font (class Font) Specifies the font to be used for the date. miltime (class Boolean) Specifies whether the military (24hr) time format should be used. reverseVideo (class ReverseVideo) Specifies that the foreground and background colors should be reversed. scroll (class Boolean) Specifies whether the digits should scroll or not. seconds (class Boolean) Specifies whether the seconds should be displayed or not. bell (class Boolean) Specifies whether the bell should sound on the half hour and on the hour. alarm (class Boolean) Specifies whether the alarm should go off at the specified time (alarmTime). alarmTime (class String) Specifies the time alarm goes off if alarm is set. Environment Variables 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 RESOURCEMANAGER property.
