    <title>Details of Usage</title>

<para>
The <emphasis role="bold"><property>&lt;rich:dropListener&gt;</property></emphasis> is used as a nested tag with components like
<emphasis role="bold"><property>&lt;rich:dropSupport&gt;</property></emphasis>, <emphasis role="bold"><property>&lt;rich:tree&gt;</property></emphasis> and <emphasis role="bold"><property>&lt;rich:treeNode&gt;</property></emphasis>.
</para>
<para>
Attribute <emphasis><property>&quot;type&quot;</property></emphasis> defines the fully qualified Java class name for the listener.
  This class should implement org.richfaces.event.DropListener <ulink url="http://labs.jboss.com/file-access/default/members/jbossrichfaces/freezone/docs/apidoc_framework/index.html">interface</ulink>.
