        $desc = new WysiwygTextarea('desc',$buttons);
        $desc->setLabel($language->text('event', 'add_form_desc_label'));
        $desc->setRequired();
        $this->addElement($desc);

Worked like a charm! Thanks for your expertise and time Bro :)

Awesome.

Matt

Welcome :) Happy to help :)

Any idea how some one might do the same thing for the catalog plugin? I tried looking for the same string of info, but it's not the same. 

How to do this in 1.7.2??

thanks

I guess it should work the same way, if the core editor has not changed.

i think it is because i cant find that code 

Thanks

Are you checking in events plugin code?

yes

Please PM me with details of the files so that I can help

I've just tried this code change on a fresh install - V1.7.5 (build 9600)

When applied only three new buttons appear More, Photo, Video - what I'm really after is the Switch to HTML one.

Any ideas why this one (and others) are missing?

thanks

Clear cache and try if you made any changes.

@Purusothaman Ramanujam  - I've tried clearing the borwser cache and even a different browser, but I'm only seeing the three extra buttons, but not the HTML one.

Not sure unless I see what is done.

This is what I have now:

$buttons = array(           
BOL_TextFormatService::WS_BTN_BOLD,           
BOL_TextFormatService::WS_BTN_ITALIC,           
BOL_TextFormatService::WS_BTN_UNDERLINE,           
BOL_TextFormatService::WS_BTN_IMAGE,           
BOL_TextFormatService::WS_BTN_LINK,           
BOL_TextFormatService::WS_BTN_ORDERED_LIST,            BOL_TextFormatService::WS_BTN_UNORDERED_LIST,           
BOL_TextFormatService::WS_BTN_MORE,           
BOL_TextFormatService::WS_BTN_SWITCH_HTML,           
BOL_TextFormatService::WS_BTN_HTML,           
BOL_TextFormatService::WS_BTN_VIDEO        );
        $desc = new WysiwygTextarea('desc',$buttons);
        $desc->setLabel($language->text('event', 'add_form_desc_label'));
        $desc->setRequired();

$event = new OW_Event(self::EVENT_NAME, array( 'name' => 'desc' ), $desc);        OW::getEventManager()->trigger($event);       
$desc = $event->getData();

$this->addElement($desc);
