property StructureElements: TPdfStructureElements; // read only
Indexed read-only property that returns the children of a logical structure tree element (StructTree)
Requires Active to be True. The result is undefined when the index is outside the valid range; pass values in 0 .. - 1 (or use the array's Length for non-counted variants).
The returned record is a snapshot of the value at the time of the call; subsequent edits to the document do not modify previously returned records.
