alias Gtk::TreeListModelCreateModelFunc


Prototype of the function called to create new child models when gtk_tree_list_row_set_expanded() is called.

This function can return %NULL to indicate that @item is guaranteed to be a leaf node and will never have children. If it does not have children but may get children later, it should return an empty model that is filled once children arrive.
