PolyNode.GetNext
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 ...
PolyTree polytree;
//call to Clipper.Execute method here which fills 'polytree'
PolyNode* polynode = polytree.GetFirst();
while (polynode)
{
//do stuff with polynode here
polynode = polynode->GetNext();
}
