Remarks

Call this function to place a newly created node as the first sibling of a node passed as the Node parameter. Passing nil instead of a tree node results in appending a node to the root level. The Add function returns the node object. Pass a pointer to custom data or nil as the Data parameter to initialize the created node’s Data property.

To append a new node as a child instead of a sibling to the specified node, call the AddChild function.

Calling the AddFirst function raises the OnCreateNode event.
