xapm

XAPM(1) 																   XAPM(1)

NAME

       xapm - display Advanced Power Management (APM) BIOS information

SYNOPSIS

       xapm [ ... ]

DESCRIPTION

       xapm  puts up an X window that displays the remaining battery life.  The left side of the window contains a printed time or percentage; the
       right side of the window contains a bar indicating the percentage.  Clicking on the left side of the window will toggle the display between
       time and percentage.

OPTIONS AND RESOURCES

       In addition to standard Xt options, the following options are available:

       -V     Print the program version number and exit.

       -highcolor color
	      The color of the bar when the battery percentage is above highvalue.  Defaults to "green". (*highColor)

       -lowcolor color
	      The color of the bar when the battery percentage is between lowvalue and highvalue.  Defaults to "yellow". (*lowColor)

       -criticalcolor color
	      The  color  of  the  bar	when  the  battery percentage is below lowvalue.  Defaults to "red".  This color is also used to flash the
	      alphanumeric part of the display when the power status is critical. (*criticalCOlor)

       -highvalue highvalue
	      Set highvalue.  The default is 50. (*highValue)

       -lowvalue lowvalue
	      Set lowvalue.  The default is 10. (*lowValue)

       -chargingcolor color
	      The color of the printed display when charging.  The default is "blue".  Use -foreground to change the color used  when  on  battery
	      power. (*chargingColor)

       -delay delay
	      Sets the number of seconds delay between each update.  The default is 1. (*delay)

       -percent
	      Display percentage on startup, instead of time remaining. (*percent, boolean)

       -percentauto
	      Swap  automatically  between  displaying percentage and displaying the time remaining. When on ac power, display percentage, when on
	      battery power, display the time remaining.

BUGS

       There is no way to inhibit the alphanumeric display or the bar display.	When the battery percentage is low, using a bright color  to  warn
       you  of	impending  doom  may be futile because the bar is too short.  Because of the form widget's desire to maintain proportions, dynamic
       resizing of the window may not do what you want it to do.
