    <title>Details of Usage</title>
    <para>The main component function is to define a content group that is rendered and processed when the <property>tab</property> is active, i.e. click on a <property>tab</property> causes switching onto a <property>tab</property> containing content corresponded to this <property>tab</property>.</para>
    <para>The <emphasis ><property>&quot;label&quot;</property></emphasis > attribute defines text to be represented. If you can use the
      <emphasis><property>&quot;label&quot;</property></emphasis> facet, you can even not use the <emphasis ><property>&quot;label&quot;</property></emphasis > attribute.</para>
    <para>

    <para>A marker on a <property>tab</property> header defined with the <emphasis ><property>&quot;label&quot;</property></emphasis> attribute. Moreover, each <property>tab</property> could be disabled (switching on this <property>tab</property> is impossible) with the <emphasis ><property>&quot;disable&quot;</property></emphasis> attribute.</para>

    <para>
      <emphasis role="bold">Example:</emphasis>
    </para>
    <programlisting role="XML"><![CDATA[...

    </rich:tabPanel>

<para>With this example it&apos;s possible to generate the <property>tab panel</property>
 with the last disabled and three active <property>tabs</property> (see the picture).</para>

  </figure>
<para>Switching mode could be defined not only for the whole panel <property>tab</property>, but also 
for each particular <property>tab</property>, i.e. switching onto one <property>tab</property> could be
 performed right on the client with the corresponding JavaScript and onto another 
 <property>tab</property> with an Ajax request on the server. <property>Tab</property> switching modes
  are the same as <property>tabPanel</property> ones.</para>
<para>Each <property>tab</property> also has an attribute name (alias for <emphasis ><property>&quot;id&quot;</property></emphasis> attribute). Using this attribute value it&apos;s possible e.g. to set an active <property>tab</property> on a model level specifying this name in the corresponding attribute of the whole <property>tab</property>.</para>
<para>Except the specific component attributes it has all necessary attributes for JavaScript event definition.</para>

    <para>
      Some event could be performed on the tab which has been entered/left using <emphasis><property>&quot;ontabenter&quot;</property></emphasis>/<emphasis><property>&quot;ontableave&quot;</property></emphasis> attributes. See the example below.</para>
