Declaration
property HotTrack: Boolean read GetHotTrack write SetHotTrack default False;Description
HotTrack is a
Boolean property which controls whether a
hot-tracking highlight is drawn for the tree node under the mouse cursor. When
enabled, the text for the hovered tree node is drawn using an underline
drawing style and the optional HotTrackColor defined for the control. The
default value for the property is
False and disables hot-track
highlighting on the control.
The property value is read from and written to the Options property for the control; the value tvoHotTrack is included in or excluded from Options based on the property value. Setting HotTrack to True causes tvoHotTrack to be included in the Options property.
HotTrack is used in methods like DoPaintNode, MouseLeave, and MouseMove.
Use HotTrackColor to set the font color used to draw the hot-tracked tree node. Theme element details are used to get the background color for a hot-tracked tree node.
