Class TAbstractInternalGroupingNode
Unit
Declaration
type TAbstractInternalGroupingNode = class(TAbstractChildNode)
Description
Base node that may contain children nodes.
You should not use this class directly usually, instead use e.g. TAbstractGroupingNode. This class is a common ancestor to help implementing a few similar nodes, like TAbstractGroupingNode and TStaticGroupNode, but it is undefined whether they will always rely on this common ancestor.
Note: This descends from TAbstractChildNode, so it can be inserted as child of another grouping node. So, you can create a hierarchy of nodes with any depth.
Handles TTransformFunctionality for any descendant that defines an instance of it.

This item has no description. Showing description inherited from TX3DNode.BeforeTraverse. Override these methods to determine what happens when given node is traversed during Traverse call. The main use of this is to operate on TX3DGraphTraverseStateStack. Remember to always call inherited when overriding. In Besides changing StateStack.Top fields, you can do push/pop on the stack.
