    <title>Creating the Component with a Page Tag</title>
    <para>To create the simplest variant on a page use the following syntax:</para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...
    <rich:toolBar>
        <rich:draggable dragType="file">
            <!--Some Content to be Dragged-->
        </rich:draggable>
        ...
    </rich:toolBar>
]]></programlisting>

    <title>Creating the Component Dynamically Using Java</title>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="JAVA"><![CDATA[...
org.richfaces.component.html.HtmlDraggable myDragZone = new org.richfaces.component.html.HtmlDraggable();
...
]]></programlisting>
  </section>
  <section>
    <title>Details of Usage</title>
    <para>As it shown in the example, a key attribute is <emphasis ><property>&quot;dragType&quot;</property></emphasis>, where a name for an obtaining Drag-area is defined. Basing on this name, Drop-zones on a page decide whether to accept Drag-area content or not (with the help of Drag-areas lists accepted for processing that are defined in Drop-zones).</para>
    <para><emphasis role="bold">Example:</emphasis></para>
    <programlisting role="XML"><![CDATA[...
    <rich:draggable dragType="dragTextBlocks">
        <!--Some Components There-->
    </rich:draggable>
    <rich:draggable dragType="dragIcons">
        <!--Some Components There-->
    </rich:draggable>
    ...
    <rich:dropZone acceptedTypes="[dragIcons]">
         <!--Some Content Representing DropZone-->
    <rich:dropZone>
...
]]></programlisting>
    <para>The example shows that Drop zone calls the corresponding drop event processing in it, only 
    if a drop is generated from the second drop zone. </para>
    <para>Another important attribute for 
    <emphasis role="bold"><property>&lt;rich:draggable&gt;</property></emphasis> is <emphasis ><property>&quot;dragIndicator&quot;</property></emphasis> where the 
<emphasis role="bold"><property>&lt;rich:dragIndicator&gt;</property></emphasis> component id is defined for this drag area. If it isn&apos;t defined drag area 
creates a default indicator for drag operation. Additional information on <emphasis role="bold">
        <property>&lt;rich:dragIndicator&gt;</property>
      </emphasis>and its usage with a drag, could be found on the following chapter <ulink url="ch06s04.html">
 dragIndicator</ulink>.</para>
    <para>Thus, it&apos;s necessary only to define the following:</para>
    <para><emphasis role="bold">Example:</emphasis></para>
    <programlisting role="XML"><![CDATA[...
    <rich:draggable dragType="dragText">
        <h:outputText value="Hello"></h:outputText>  
    </rich:draggable>
...
]]></programlisting>
    <para>in order to be able to drag this string on a page.</para>
    <para>The component also provide important components for redefinition of the corresponding 
    events called with the drag operations (ondragstart and ondragend), where it possible to define 
    your own additional JavaScript functions that are called on the corresponding events.</para>
  </section>
  <section>
    <title>Look-and-Feel Customization</title>
    <para>As it has been mention above, the component defines components wrapper for drag areas, i.e. 
    it doesn&apos;t has its own representation. Therefore, for customization of a wrapper 
    <emphasis role="bold"><property>&lt;div&gt;</property></emphasis> element of the component it&apos;s 
    possible to use a component attribute <emphasis ><property>&quot;styleClass&quot;</property></emphasis> or 
     redefine rich-draggable class in your own CSS files that is added to all <property>draggable</property> components
      style on default.</para>
