[−][src]Struct gstreamer::ChildProxy
This interface abstracts handling of property sets for elements with
children. Imagine elements such as mixers or polyphonic generators. They all
have multiple Pad or some kind of voice objects. Another use case are
container elements like 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 ChildProxy::get and ChildProxy::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 ChildProxy interface.
