CPortlet is the base class for portlet widgets.

A portlet displays a fragment of content, usually in terms of a block on the side bars of a Web page.

To specify the content of the portlet, override the renderContent method, or insert the content code between the CController::beginWidget and CController::endWidget calls. For example,

<?php $this->beginWidget('zii.widgets.CPortlet'); ?>
    ...insert content here...
<?php $this->endWidget(); ?>


A portlet also has an optional title. One may also override renderDecoration to further customize the decorative display of a portlet (e.g. adding min/max buttons).
