setSelected
Selects the item at the given position.
If the list does not have an item at @position or %GTK_INVALID_LIST_POSITION is given, the behavior depends on the value of the property@Gtk.SingleSelection:autoselect property: If it is set, no change will occur and the old item will stay selected. If it is unset, the selection will be unset and no item will be selected. This also applies if property@Gtk.SingleSelection:can-unselect is set to false.
Parameters
position
the item to select or %GTK_INVALID_LIST_POSITION
