TTreeNode.StateIndex property
Ordinal position for the image displayed to represent the state for the tree node.
Declaration
property StateIndex: Integer read FStateIndex write SetStateIndex default - 1;Description
StateIndex 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.
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.
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.
Use ImageIndex to specify the icon displayed for the tree node.
Use OverlayIndex to specify an overlay displayed on the icon for the tree node.
Use SelectedIndex to specify the icon displayed when the tree node is Selected.
