# Feature: #108462 - Add PSR-14 Event AfterPageContentPreviewRenderedEvent {#feature-108462-1765368045}

See [forge#108462](https://forge.typo3.org/issues/108462)

## Description {#description}

The class `\TYPO3\CMS\Backend\View\BackendLayout\Grid\GridColumnItem` is
the central entity to generate various previews of content elements.

Developers can either use the event `\TYPO3\CMS\Backend\View\Event\PageContentPreviewRenderingEvent`
to generate a preview or implementing `\TYPO3\CMS\Backend\Preview\PreviewRendererInterface`.

The new PSR-14 event `\TYPO3\CMS\Backend\View\Event\AfterPageContentPreviewRenderedEvent`
can now be used to enrich the output generated by one of those.

## Example {#example}

An example event listener could look like this:

**Example event listener class**

```php
namespace MyVendor\MyExtension\EventListener;

use TYPO3\CMS\Backend\View\Event\AfterPageContentPreviewRenderedEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener('my-extension')]
final class AfterPageContentPreviewRenderedEventListener
{
    public function __invoke(AfterPageContentPreviewRenderedEvent $event): void
    {
        $content = 'before<hr />'. $event->getPreviewContent() . '<hr />after';
        $event->setPreviewContent($content);
    }
}
```

## Impact {#impact}

As integrator it is sometimes handy to enrich the previews of other
content elements and plugins to display additional fields.
