 * $Log: widget_bar.c,v $
 * Revision 1.18  2006/01/23 06:17:18  reinelt
 * timer widget added
 *
 * Revision 1.17  2005/12/18 16:18:36  reinelt
 * GPO's added again
 *
 * Revision 1.16  2005/05/08 04:32:45  reinelt
 * CodingStyle added and applied
 *
 * Revision 1.15  2005/05/06 06:37:34  reinelt
 * hollow bar patch from geronet
 *
 * Revision 1.14  2005/01/18 06:30:24  reinelt
 * added (C) to all copyright statements
 *
 * Revision 1.13  2004/11/29 04:42:07  reinelt
 * removed the 99999 msec limit on widget update time (thanks to Petri Damsten)
 *
 * Revision 1.12  2004/06/26 12:05:00  reinelt
 *
 * uh-oh... the last CVS log message messed up things a lot...
 *
 * Revision 1.11  2004/06/26 09:27:21  reinelt
 *
 * added '-W' to CFLAGS
 * changed all C++ comments to C ones
 * cleaned up a lot of signed/unsigned mistakes
 *
 * Revision 1.10  2004/03/11 06:39:59  reinelt
 * big patch from Martin:
 * - reuse filehandles
 * - memory leaks fixed
 * - earlier busy-flag checking with HD44780
 * - reuse memory for strings in RESULT and hash
 * - netdev_fast to wavid time-consuming regex
 *
 * Revision 1.9  2004/03/06 20:31:16  reinelt
 * Complete rewrite of the evaluator to get rid of the code
 * from mark Morley (because of license issues).
 * The new Evaluator does a pre-compile of expressions, and
 * stores them in trees. Therefore it should be reasonable faster...
 *
 * Revision 1.8  2004/03/03 03:47:04  reinelt
 * big patch from Martin Hejl:
 * - use qprintf() where appropriate
 * - save CPU cycles on gettimeofday()
 * - add quit() functions to free allocated memory
 * - fixed lots of memory leaks
 *
 * Revision 1.7  2004/01/30 20:57:56  reinelt
 * HD44780 patch from Martin Hejl
 * dmalloc integrated
 *
 * Revision 1.6  2004/01/29 04:40:03  reinelt
 * every .c file includes "config.h" now
 *
 * Revision 1.5  2004/01/23 04:54:00  reinelt
 * icon widget added (not finished yet!)
 *
 * Revision 1.4  2004/01/20 14:25:12  reinelt
 * some reorganization
 * moved drv_generic to drv_generic_serial
 * moved port locking stuff to drv_generic_serial
 *
 * Revision 1.3  2004/01/20 12:45:47  reinelt
 * "Default screen" working with MatrixOrbital
 *
 * Revision 1.2  2004/01/20 04:51:39  reinelt
 * moved generic stuff from drv_MatrixOrbital to drv_generic
 * implemented new-stylish bars which are nearly finished
 *
 * Revision 1.1  2004/01/18 21:25:16  reinelt
 * Framework for bar widget opened
