TTreeNode.IndexOf function
Get the index position for the specified child tree node.
Declaration
function IndexOf(AValue: TTreeNode): IntegerArguments
AValue | Child node to locate in Items. |
Function result
Ordinal position for the specified child node, or -1 when not a child node.
Description
The return value is -1 if the tree node in AValue is not a child node (its Parent node is not the current class instance). Calls GetIndex to calculate the position of the child node relative to previous sibling nodes. Roughly equivalent to calling IndexOf in the Items container, but using a TTreeNode search value instead of a String.
