Hierarchical List is a type of list to represent data in a structured, systematic and tree-style manner. And it is widely used for standard representation of data. This article mainly deals with Hierarchical Lists API and shows the use of its CAknSingleStyleTreeList class to create the list in S60 5th Edition.

The article first gives a brief overview for the same and then represents the code snippests to create the list with CAknSingleStyleTreeList class. The code snippests are presented with necessary explainations and well-describing comments. Basic functions like adding nodes/ leaf, deleating nodes/ leaf/ the whole tree etc. are all covered by the given article. Some useful functions of the mentioned class are also mentioned in the ned of the article.

Apart from that, the article also provides a demostrated example to study the API in more detail. This article can be very beneficial to the developers who are intending to create a Hierarchical List in their application. It can specially benefit beginners.

This paper is very helpful. But I have a problem that the tree does not work well on real phone, I tested it on 5800 and n97. The folder can't expand or collapse after several clicks. I have [a topic on the discuss board][1]. Is there some thing I make wrong? --xuelanding 8 Nov 2010
