 * @file
 * Definition of the 'block' panel style.

// Plugin definition
$plugin = array(
  'title' => t('System block'),
  'description' => t('Display the pane as a system block; this is more restrictive than the default.'),
  'render pane' => 'panels_block_style_render_pane',
  'weight' => -10,

 * @ingroup themeable
function theme_panels_block_style_render_pane($vars) {
  $content = $vars['content'];
  $pane = $vars['pane'];

  if (empty($content->content)) {

  $block = clone($content);

  if (!empty($block->title)) {
    $block->subject = $block->title;

  $block->region = $pane->panel;
  if (!isset($block->module)) {
    $block->module = $block->type;
