/**

 @brief A generic implementation of the "find" function.
 <b></b>etail:
 This class includes prompt handling etc. Also provides some
 static functions which can be used to create custom behavior
 instead of using the class directly.
 <b></b>xample:
 To use the class to implement a complete find feature:
 In the slot connected to the find action, after using KFindDialog:
 <pre>
  // This creates a find-next-prompt dialog if needed.
  m_find = new KFind(pattern, options, this);
  // Connect highlight signal to code which handles highlighting
  // of found text.
  connect( m_find, TQ_SIGNAL("highlight( String, int, int )"),
          this, TQ_SLOT("slotHighlight( String, int, int )") );
  // Connect findNext signal - called when pressing the button in the dialog
  connect( m_find, TQ_SIGNAL("findNext()"),
          this, TQ_SLOT("slotFindNext()") );
 </pre>
 If you are using a non-modal find dialog (the recommended new way
 in KDE-3.2), you should call right away m_find.closeFindNextDialog().
  Then initialize the variables determining the "current position"
  (to the cursor, if the option FromCursor is set,
   to the beginning of the selection if the option SelectedText is set,
   and to the beginning of the document otherwise).
  Initialize the "end of search" variables as well (end of doc or end of selection).
  Swap begin and end if FindBackwards.
  Finally, call slotFindNext();
 <pre>
  void slotFindNext()
  {
      KFind.Result res = KFind.NoMatch;
      while ( res == KFind.NoMatch && <position not at end> ) {
          if ( m_find.needData() )
              m_find.setData( <current text fragment> );
          // Let KFind inspect the text fragment, and display a dialog if a match is found
          res = m_find.find();
          if ( res == KFind.NoMatch ) {
              <Move to the next text fragment, honoring the FindBackwards setting for the direction>
          }
      }
      if ( res == KFind.NoMatch ) // i.e. at end
          <Call either  m_find.displayFinalDialog(); delete m_find; m_find = null;
           or           if ( m_find.shouldRestart() ) { reinit (w/o FromCursor) and call slotFindNext(); }
                        else { m_find.closeFindNextDialog(); }>
  }
 </pre>
  Don't forget to delete m_find in the destructor of your class,
  unless you gave it a parent widget on construction.
  This implementation allows to have a "Find Next" action, which resumes the
  search, even if the user closed the "Find Next" dialog.
  A "Find Previous" action can simply switch temporarily the value of
  FindBackwards and call slotFindNext() - and reset the value afterwards.
