http://harmattan-dev.nokia.com/docs/library/html/qt4/qlinkedlist.html
QLinkedList stores a list of items. The default constructor creates an empty list. To insert items into the list, you can use operator<<():
QLinkedList<QString> list; list << "one" << "two" << "three"; // list: ["one", "two", "three"]
void QLinkedList::append ( const T & value )
Inserts value at the end of the list.
QLinkedList<QString> list; list.append("one"); list.append("two"); list.append("three"); // list: ["one", "two", "three"]
