Block styles not included when using block->display()

Permalink
I noticed that when inserting a block like this:
public function view() {
   $stack = Stack::getByID(140);
   $block = $stack->getBlocks()[0];
   $this->set('block', $block->display());                  
}

Then the block styles added by clicking on the block and selecting 'Design' aren't added to the block. If adding the stack to a page normally, they are. Anyone know how to include those block styles programmatically?

Here's how to output the custom styling for the stack:
$this->addHeaderItem('<style type="text/css">' . $stack->outputCustomStyleHeaderItems(true) . '</style>');


This needs to be in your controller's "on_start" (for single pages) or "on_page_view" (fo blocks) method.

And to wrap the correct CSS classes/id around the block area (so that the styles get applied), do something similar to this file:
/concrete/elements/block_area_header_view.php

Thanks for this mainio. In regards to my PM's and to help others, in my case, i added the following to my on_page_view($page) function in my block controller to get the custom block styles:
(a bit of code borrowed from core_stack_display)
$blocks = $stack->getBlocks();
   foreach($blocks as $b) {
      $btc = $b->getInstance();
      if('Controller' != get_class($btc)){
         $btc->outputAutoHeaderItems();
      }
      $csr = $b->getBlockCustomStyleRule();
      if (is_object($csr)) {
         $styleHeader = '#'.$csr->getCustomStyleRuleCSSID(1).' {'. $csr->getCustomStyleRuleText(). "} \r\n";  
         $btc->addHeaderItem("<style type=\"text/css\"> \r\n".$styleHeader.'</style>', 'VIEW');
      }
      $btc->runTask('on_page_view', array($page));
         }
