Table 6.167. Component identification parameters

NameValue
listener-classorg.richfaces.event.DropListener
event-classorg.richfaces.event.DropEvent
tag-classorg.richfaces.taglib.DropListenerTag

To create the simplest variant on a page use the following syntax:

Example:


...
    <rich:dropListener type="demo.Bean"/>
...

Example:

package demo;

      
public class ImplBean implements org.richfaces.event.DropListener{
    ...
}


import demo.ImplBean;
...
ImplBean myListener = new ImplBean();
...

The <rich:dropListener> is used as a nested tag with components like <rich:dropSupport> , <rich:tree> and <rich:treeNode> .

Attribute "type" defines the fully qualified Java class name for the listener. This class should implement org.richfaces.event.DropListener interface .

The typical variant of using:


...
<rich:panel style="width:100px;height:100px;">
    <f:facet name="header">Drop Zone</f:facet>
    <rich:dropSupport acceptedTypes="text"> 
        <rich:dropListener type="demo.ListenerBean"/>
    </rich:dropSupport>             
</rich:panel>
...

Java bean source:

package demo;


import org.richfaces.event.DropEvent;
public class ListenerBean implements org.richfaces.event.DropListener{
... 
    public void processDrop(DropEvent arg0){
        //Custom Developer Code 
    }
...
}

<rich:dropListener> has no skin parameters and custom style classes , as the component isn't visual.
