As opposed - to QStrList, that stores pointers to characters, QStringList deals - with real QString objects. It is the class of choice whenever you - work with unicode strings. - - Like QString itself, QStringList objects are implicit shared. - Passing them around as value-parameters is both fast and safe. - - Example: - \code - QStringList list; - - // three different ways of appending values: - list.append( "Torben"); - list += "Warwick"; - list << "Matthias" << "Arnt" << "Paul"; - - // sort the list, Arnt's now first - list.sort(); - - // print it out - for ( QStringList::Iterator it = list.begin(); it != list.end(); ++it ) { - printf( "%s \n", (*it).latin1() ); - } - \endcode - - Convenience methods such as sort(), split(), join() and grep() make - working with QStringList easy. -*/ - -/*! - \fn QStringList::QStringList() - Creates an empty list. -*/ - -/*! \fn QStringList::QStringList( const QStringList& l ) - Creates a copy of the list.
