Del.» function GetNext: TPolyNode;
C++ » PolyNode* GetNext();
C# » public PolyNode GetNext();
 The returned Polynode will be the first child if any, otherwise the next sibling, otherwise the next sibling of the Parent etc.
 A PolyTree can be traversed very easily by calling GetFirst() followed by GetNext() in a loop until the returned object is a null pointer ...

  PolyNode* polynode = polytree.GetFirst();
  while (polynode)

    //do stuff with polynode here
	
    polynode = polynode->GetNext();
