- Displays the Drupal administration interface in an overlay.
Code
function overlay_overlay_child_initialize() { // Check if the parent window needs to refresh any page regions on this page // request. overlay_trigger_refresh(); // If this is a POST request, or a GET request with a token parameter, we // have an indication that something in the supplemental regions of the // overlay might change during the current page request. We therefore store // the initial rendered content of those regions here, so that we can compare // it to the same content rendered in overlay_exit(), at the end of the page // request. This allows us to check if anything actually did change, and, if // so, trigger an immediate Ajax refresh of the parent window. if (!empty($_POST) || isset($_GET['token'])) { foreach (overlay_supplemental_regions() as $region) { overlay_store_rendered_content($region, overlay_render_region($region)); } // In addition, notify the parent window that when the overlay closes, // the entire parent window should be refreshed. overlay_request_page_refresh(); } // Indicate that when the main page rendering occurs later in the page // request, only the regions that appear within the overlay should be // rendered. overlay_set_regions_to_render(overlay_regions()); }
