  * History:
  * $Log$
+ * Revision 1.6  2003/07/07 16:19:47  eilers
+ * Fixing serious bug in hasQuerySettings()
+ *
  * Revision 1.5  2003/04/13 18:07:10  zecke
  * More API doc
  * QString -> const QString&
  * QString = 0l -> QString::null
  *
  * Revision 1.4  2003/03/21 14:32:54  mickeyl
  * g++ compliance fix: default arguments belong into the declaration, but not the definition
  *
  * Revision 1.3  2003/03/21 12:26:28  eilers
  * Fixing small bug: If we search a birthday from today to today, it returned
  * every contact ..
  *
  * Revision 1.2  2003/03/21 10:33:09  eilers
  * Merged speed optimized xml backend for contacts to main.
  * Added QDateTime to querybyexample. For instance, it is now possible to get
  * all Birthdays/Anniversaries between two dates. This should be used
  * to show all birthdays in the datebook..
  * This change is sourcecode backward compatible but you have to upgrade
  * the binaries for today-addressbook.
  *
  * Revision 1.1.2.2  2003/02/11 12:17:28  eilers
  * Speed optimization. Removed the sequential search loops.
  *
  * Revision 1.1.2.1  2003/02/10 15:31:38  eilers
  * Writing offsets to debug output..
  *
  * Revision 1.1  2003/02/09 15:05:01  eilers
  * Nothing happened.. Just some cleanup before I will start..
  *
  * Revision 1.12  2003/01/03 16:58:03  eilers
  * Reenable debug output
  *
  * Revision 1.11  2003/01/03 12:31:28  eilers
  * Bugfix for calculating data diffs..
  *
  * Revision 1.10  2003/01/02 14:27:12  eilers
  * Improved query by example: Search by date is possible.. First step
  * for a today plugin for birthdays..
  *
  * Revision 1.9  2002/12/08 12:48:57  eilers
  * Moved journal-enum from ocontact into i the xml-backend..
  *
  * Revision 1.8  2002/11/14 17:04:24  eilers
  * Sorting will now work if fullname is identical on some entries
  *
  * Revision 1.7  2002/11/13 15:02:46  eilers
  * Small Bug in sorted fixed
