Where can I get more information on constructing these Directory trees?

I don't know how to perform the following statement:

dirName is a string
pageName is also a string

addNodeToTree (treeControl1.getRoot(), dirName, pageName);

  void addNodeToTree (GraphLocation d, TreeControl t, String s) {
   // adds the child nodes
   GraphLocation node = t.addChild(d, s);
  }

Ultimately this would make a tree like:
v Root
    v dirName
        > pageName
        > pageName
    v dirName
        > pageName
        > etc.

Thanks...
