<var>StateIndex</var> the index of the state (within an enumerated type).
<var>StateIndex</var> refers to a position in StateImages for the associated
TreeView control. It determines the image displayed to the left of the icon
image specified in ImageIndex. The default value for the property is -1, and
indicates that an image has not been assigned to represent the state for the
tree node.

<p>Definition of enumerated type NodeState:</p>

nsCut, nsDropHilited, nsFocused, nsSelected, nsMultiSelected, nsExpanded,
nsHasChildren, nsDeleting, nsBound
Changing the value for the property causes the tree node and the associated
TreeView control to be redrawn. The Changed method is called to notify the
TreeView control of the reason for the update.

<p>
StateIndex can be used (along with StateImages in TreeView) to approximate the
check box available for tree nodes in Delphi VCL but not in LCL.

Use StateImages in TTreeView / TCustomTreeView to specify the available state images.
