Support for Panel tabs

Hello,

I work on the implementation of twitter bootstrap tab system (instead of jquery ui one) for the Panel tabs module.

Feel free to implement it. Personnaly, I put that code in includes/modules/panels_tabs.inc to follow the theme logic (and add an include_once in template.php).

Here is the code :

function twitter_bootstrap_panels_tabs_style_render_region($vars) {
	
  $display = $vars['display'];
  $region_id = $vars['region_id'];
  $owner_id = $vars['owner_id'];
  $panes = $vars['panes'];

  $tab_id = 'tabs-' . $owner_id . '-' . $region_id;

  $settings = array();
  $settings['panelsTabs']['tabsID'][] = $tab_id;

  // Get the pane titles.
  $items = array();
  $delta = 1;
  foreach ($display->panels[$region_id] as $pane_id) {
    // Make sure the pane exists.
    if (!empty($panes[$pane_id])) {
      $title = panels_tabs_pane_titles($display->did, $pane_id);
      $title = $title ? $title : t('Tab @delta', array('@delta' => $delta));
			// Set active class for first tab
			if($delta == 1) {
				$items[] = array(
					'data' => '<a href="#'. $tab_id . '-' . $delta .'" data-toggle="tab">' . $title . '</a>',
					'class' => array('active')
				);
			} else {
				$items[] = array(
					'data' => '<a href="#'. $tab_id . '-' . $delta .'" data-toggle="tab">' . $title . '</a>',
				);
			}
      ++$delta;
    }
  }

  $element['tabs_title'] = array('#theme' => 'item_list', '#items' => $items, '#type' => 'ul', '#attributes' => array('class' => 'nav nav-tabs'));

  $items = array();
  $delta = 1;
	
  foreach ($panes as $pane_id => $item) {
		if($delta == 1) {
			$class = 'tab-pane active';
		} else {
			$class = 'tab-pane';
		}
    $element['tabs_content'][$pane_id] = array(
      '#prefix' => '<div class="'.$class.'" id="' . $tab_id . '-' . $delta . '">',
      '#suffix' => '</div>',
      '#markup' => $item,
    );
    ++$delta;
  }
	
	$element['tabs_content']['#prefix'] = '<div class="tab-content">';
	$element['tabs_content']['#suffix'] = '</div>';
  return drupal_render($element);
}
