Interface: renderable - X-Ref
Interface marking other classes as suitable for renderer_base::render()Interface: templatable - X-Ref
Interface marking other classes having the ability to export their data for use by templates.| export_for_template(renderer_base $output) X-Ref |
| Function to export the renderer data in a format that is suitable for a mustache template. This means: 1. No complex types - only stdClass, array, int, string, float, bool 2. Any additional info that is required for the template is pre-calculated (e.g. capability checks). param: renderer_base $output Used to do a final render of any components that need to be rendered for export. return: stdClass|array |
Class: file_picker - X-Ref
Data structure representing a file picker.| __construct(stdClass $options) X-Ref |
| Constructs a file picker object. The following are possible options for the filepicker: - accepted_types (*) - return_types (FILE_INTERNAL) - env (filepicker) - client_id (uniqid) - itemid (0) - maxbytes (-1) - maxfiles (1) - buttonname (false) param: stdClass $options An object containing options for the file picker. |

Multiple row tabs may not look good on some devices but if you want to use them
you can specify ->subtree for the active tabobject.
