Gets the first ancestor of widget with type widget_type. For example,
gtk_widget_get_ancestor (widget, GTK_TYPE_BOX) gets
the first #GtkBox that’s an ancestor of widget. No reference will be
added to the returned widget; it should not be unreferenced. See note
about checking for a toplevel #GtkWindow in the docs for
gtk.widget.Widget.getToplevel.
