Gst.ChildProxy

const Gst = imports.gi.Gst;

let child_proxy = new Gst.ChildProxy();
  

This interface abstracts handling of property sets for elements with children. Imagine elements such as mixers or polyphonic generators. They all have multiple Gst.Pad or some kind of voice objects. Another use case are container elements like Gst.Bin. The element implementing the interface acts as a parent for those child objects.

By implementing this interface the child properties can be accessed from the parent element by using Gst.get and Gst.set.

Property names are written as "child-name::property-name". The whole naming scheme is recursive. Thus "child1::child2::property" is valid too, if "child1" and "child2" implement the Gst.ChildProxy interface.
