public virtual signal void queue_relayout ()
::queue_layout signal is emitted when queue_relayout is called on an actor.
The default implementation for Actor chains up to the parent actor and queues a relayout on the parent, thus "bubbling" the relayout queue up through the actor graph.
The main purpose of this signal is to allow relayout to be propagated properly in the presence of Clone actors. Applications will not normally need to connect to this signal.
