HotTrackAutoExpand: Boolean;
HotTrackAutoExpand: Boolean;
The HotTrackAutoExpand property determines whether the state of children tree is changed on clicking a selected element.
If the property is set to True, on clicking the selected element its child elements hierarchy is collapsed/expanded, in other case the child elements hierarchy state is not altered.
Also, on clicking the selected node its selection is modified according to the settings defined in the SelectionMode property.
The HotTrackAutoExpand property is relevant if the HotTrack property is set to True.
NOTE. If the HotTrackAutoExpand property is set to True, the tree state modification on clicking an element is executed with a slight delay. The tree state modification on double click is not available in such conditions.
