Draggableviews module provides a style plugin for views. With this plugin rows become draggable and can be organized in complex structures.

Code

function draggableviews_discover_handlers($filter_handler = NULL) {

  // @todo there's no cache functionality implemented yet.
  $cache = array();

  // Get implementation definitions from all modules.
  foreach (module_implements('draggableviews_handlers') as $module) {
    $function = $module . '_draggableviews_handlers';
    $result = $function();
    if (!is_array($result)) {
      continue;
    }
    $path = drupal_get_path('module', $module);
    foreach ($result as $handler => $def) {
      if (!isset($def['path'])) {
        $def['path'] = $path;
      }
      if (!isset($def['file'])) {
        $def['file'] = "{$handler}.inc";
      }
      if (!isset($def['handler'])) {
        $def['handler'] = 'draggableviews_handler_' . $handler;
      }

      // Merge the new data.
