Struct gstreamer::ChildProxy
source · #[repr(transparent)]pub struct ChildProxy { /* private fields */ }Expand description
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 gst_child_proxy_get() and gst_child_proxy_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.
Signals
child-added
Will be emitted after the object was added to the child_proxy.
child-removed
Will be emitted after the object was removed from the child_proxy.
