Karroffel 390f7def39 add "propagate_call" method to Node ... It is possible to propagate a notification down the Node tree by using `propagate_notification`, but there was no such method for doing the same but with method calls. This commit adds the `propagate_call` method, which calls a method on a node and all child nodes. An optional paramter `parent_first` determines whether the parent node gets called before or after the children have been visited. It defaults to false, so the parent gets called last.		2017-08-19 15:22:37 +02:00
