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

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

Accessor of the hover-selection slot of the gtk:tree-view class. The gtk:tree-view-hover-selection function returns whether hover selection mode is turned on for the tree view. The (setf gtk:tree-view-hover-selection) function enables or disables the hover selection mode. 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.
