PDFOUTLINENODE_Count
IPDFDocument3 :: Outlines

See Also Example
Collapse All

This property gets the number of direct descendants of a node.

Syntax

LONG PDFOUTLINENODE_Count { get; }
Value
Number of descendant nodes

Remarks

This property returns the number of direct children for a node, but not the total number of children in the node subtree (unless all are direct).

Equivalent in new interface: IPDFDocument4::GetOutlineChildCount.
