Hi folks im trying to hide add new widget when user lands on sertain page.

public function hide_add_new_widjet(BASE_CLASS_EventCollector $event)

OW::getEventManager()->bind('base.add_new_content_item', array($this, "hide_add_new_widjet"));

in:

add_new_content.php

this code:

$event = new BASE_CLASS_EventCollector(self::EVENT_NAME);
        OW::getEventManager()->trigger($event);
        $data = $event->getData();
        if( empty($data) )
        {
            $this->setVisible(false);
            return;
        }
        $this->assign('items', $event->getData());
    }

if you add this:

$this->setVisible(false);

it will hide but how can i do it from my event_handler.
