public bool hover_selection { get; set; }
Enables or disables the hover selection mode of tree_view.
Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes gtk_selection_single and gtk_selection_browse.
This mode is primarily intended for treeviews in popups, e.g. in ComboBox or EntryCompletion.
