This method is invoked right after a widget is executed.

The method will trigger the [[EVENT_AFTER_RUN]] event. The return value of the method
will be used as the widget return value.

If you override this method, your code should look like the following:

```php
public function afterRun($result)
{
$result = parent::afterRun($result);
// your custom code here
return $result;
}
```

@param mixed $result the widget return result.
@return mixed the processed widget result.
