Class: inplace_editable  - X-Ref

Class allowing to quick edit a title inline

This class is used for displaying an element that can be in-place edited by the user. To display call:
echo $OUTPUT->render($element);
or
echo $OUTPUT->render_from_template('core/inplace_editable', $element->export_for_template($OUTPUT));

Template core/inplace_editable will automatically load javascript module with the same name
core/inplace_editable. Javascript module registers a click-listener on edit link and
then replaces the displayed value with an input field. On "Enter" it sends a request
to web service core_update_inplace_editable, which invokes the callback from the component.
Any exception thrown by the web service (or callback) is displayed as an error popup.

Callback {$component}_inplace_editable($itemtype, $itemid, $newvalue) must be present in the lib.php file of
the component or plugin. It must return instance of this class.
