<div class="textblock"><p>Interface for multi child elements. </p>
<p>This interface abstracts handling of property sets for elements with children. Imagine elements such as mixers or polyphonic generators. They all have multiple <a class="el" href="classGst_1_1Pad.html" title="A class that represents objects contained by elements that allows links to other elements. ">Gst::Pad</a> or some kind of voice objects. Another use case are container elements like <a class="el" href="classGst_1_1Bin.html" title="Base class and element that can contain other elements. ">Gst::Bin</a>. The element implementing the interface acts as a parent for those child objects.</p>
<p>By implementing this interface the child properties can be accessed from the parent element by using <a class="el" href="classGst_1_1ChildProxy.html#addfd14f633d4263139b513729b26d526" title="Gets a single property using the Gst::ChildProxy mechanism. ">get_proxy_property()</a> and <a class="el" href="classGst_1_1ChildProxy.html#a18e0a3e9f5588ebf8e25f7be43b1b7dc" title="Sets a single property using the Gst::ChildProxy mechanism. ">set_proxy_property()</a>.</p>
<p>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 <a class="el" href="classGst_1_1ChildProxy.html" title="Interface for multi child elements.
