Widget.getAncestor

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.

Note that unlike gtk.widget.Widget.isAncestor, gtk.widget.Widget.getAncestor considers widget to be an ancestor of itself.
