The only way I have found to do it is make a callback function...
and use a bool m_UserNameFound to determine if it is in the list.  Is 
there a better way?


m_refListStore->foreach_iter( sigc::mem_fun( *this, 
&winPreferences::m_bFindUserName ) );


bool winPreferences::m_bFindUserName( const Gtk::TreeModel::iterator 
&iter ){
  
   Glib::ustring strText = txt_D_User_Name->get_text();
   Gtk::TreeModel::Row row = *iter;
   string strTest = row[m_ModelColumns.m_col_text];
  
   if ( strText == strTest ){
       m_UserNameFound = true;
       return true;
   }
  
   else
       return false;
  
}
