Hello,
I'd like to obtain this under but I don't know what I must to use. I need to access to the father of an object; I give you the idea under here:
Qt Code: 
  1. public class MyElemNode extends MyNode {
  2. 	List<MyNode> child = new ArrayList<MyNode>();
  3.  
  4. 	public MyElemNode() { }
  5. 	public MyNode getFirstChild() { return child.get(0);  }
  6. 	public MyNode getLastChild() { return child.get( child.size()-1 );  }
  7. 	public MyNode nextSiblingNode() { //1
  8.                        int i = getPositionOfThisObjectInFather.child();
  9.                        return  father.child(i+1);
  10.             }
  11. }
  12. //main
  13.   MyElemNode e = new  MyElemNode();
  14.  e. add( new  MyElemNode, new  MyElemNode ......................);
  15.   MyElemNode ep = e.get(5); //assuming it exists
  16.    MyElemNode sib =    ep.nextSibling();   // how to obtain this?
