Constructs an OpenModalDialog object.
The modal dialog differs from the normal modal provided by OpenDialogCommand in that a modal prevents other interactions on the page until the modal has been completed. Drupal provides a built-in modal for this purpose, so no selector needs to be provided.
string $title: The title of the dialog.
string $html: HTML that will be placed in the dialog.
array $dialog_options: (optional) Settings to be passed to the dialog implementation. Any jQuery UI option can be used. See http://api.jqueryui.com/dialog.
array|null $settings: (optional) Custom settings that will be passed to the Drupal behaviors on the content of the dialog. If left empty, the settings will be populated automatically from the current request.
Overrides OpenDialogCommand::__construct
public function __construct($title, $html, array $dialog_options = array(), $settings = NULL) {
$dialog_options['modal'] = TRUE;
parent::__construct('#drupal-modal', $title, $html, $dialog_options, $settings);
}
