Issue in iterating PolyTree

PolyTree.txt
This is how we are iterating over PolyTree in Clipper1 using GetFirst() and GetNext() functions.
We are facing issue in iterating PolyTree in Clipper2 . Is there any way to iterate PolyTree?

I really don't understand the need for these.
Why use a tree structure if you're going to use it like a list?
It's much more efficient to use list structures (ie Paths) instead.

we are facing issue to iterate polygon of childs . we are able to access only one child polygon and unable to access second child polygon.

What language are you using?

[abhijitpatil181]

c++

[AngusJohnson]

void PrintPolyPath(const PolyPath64& pp) 
{
  std::cout << pp.Polygon() << std::endl;
  for (auto child : pp)
    PrintPolyPath(*child);
}

void PrintPolytree(const PolyTree64& pt)
{
  for (auto child : pt)
    PrintPolyPath(*child);
}

int main(int argc, char* argv[])
{
  PolyTree64 pt;
  // populate pt with a clipping op
  PrintPolytree(pt);
}

Edit:

we are facing issue to iterate polygon of childs .

Note: Each child only has one polygon.
