Tree view on Cocoa

I am quite new to Cocoa framework in terms of both language and framework. What is the equivalent class for creating a Tree view on Mac OS X. I am trying to port an UI on Mac OS X. In this, a tree view is used to store some names and names under them. They are being set by a function provided by me (say AddItemUnder).

How to create tree view on Mac OS X? I saw NSOutlineView. But that requires some data source. In my case, I do not have any data source.

Also, in my case, only UI related will be in Objective-C. Rest code will be in C++ and may be common for both Windows and Mac OS X.

Currently, I need tree-view where I can add items like a hierarchical tree.

In my case, I do not have any data source.

If you don't have any data, what are you going to display on OSX GUI?

I would say you certainly have a data that is called Model, and you use GUI for the View part, and to bind Model with View you need a Controller. You are given a controller called NSTreeController.

If you are not happy with TreeController, then you can go for NSMutableDictionary and go on to add objects under objects upto any level.

Something like this :

@"World":@"worldKey"    
     -@"Asia":@"asiaKey"
           -@"India@":@"indiaKey"
                 -@"Bangalore:@"bangaloreKey"
           -@"@"Japan":@"japanKey" 
     -@"Europe":@"europeKey"   
           -@"England":@"englandKey"
                 -@"OldTrafford":@"oldTraffordKey"
     -@"Australia":@"australiaKey"
           -@"NewSouthWales:@"newSouthWalesKey"
