* $Log: widget_bar.h,v $
* Revision 1.3 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 1.2 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
