gtk:tree-view-hover-selection (object)

object -- a gtk:tree-view widget
setting -- true to enable hover selection mode

The accessor for the hover-selection slot gets or sets whether hover selection mode is turned on for the tree view. Hover selection makes the selected row follow the pointer. Currently, this works only for the :single and :browse selection modes. The gtk:tree-view implementation is deprecated since 4.10. Please do not use it in newly written code.
