749 *
750 * Note that neither the repository nor the widget instances can be created by using their constructors.
751 * A repository instance is automatically set up by the Widget plugin and is accessible under
752 * {@link CKEDITOR.editor#widgets}, while widget instances are created and destroyed by the repository.
753 *
754 * To create a widget, first you need to {@link CKEDITOR.plugins.widget.repository#add register} its
755 * {@link CKEDITOR.plugins.widget.definition definition}:
756 *
757 * editor.widgets.add( 'simplebox', {
758 * upcast: function( element ) {
759 * // Defines which elements will become widgets.
760 * if ( element.hasClass( 'simplebox' ) )
761 * return true;
762 * },
763 * init: function() {
764 * // ...
765 * }
766 * } );
767 *
768 * Once the widget definition is registered, widgets will be automatically
769 * created when loading data:
770 *
771 * editor.setData( '<div class="simplebox">foo</div>', function() {
772 * console.log( editor.widgets.instances ); // -> An object containing one instance.
773 * } );
774 *
775 * It is also possible to create instances during runtime by using a command
776 * (if a {@link CKEDITOR.plugins.widget.definition#template} property was defined):
777 *
778 * // You can execute an automatically defined command to
779 * // insert a new simplebox widget or edit the one currently focused.
780 * editor.execCommand( 'simplebox' );
781 *
782 * Note: Since CKEditor 4.5 widget's `startupData` can be passed as the command argument:
783 *
784 * editor.execCommand( 'simplebox', {
785 * startupData: {
786 * align: 'left'
787 * }
788 * } );
789 *
790 * A widget can also be created in a completely custom way:
791 *
792 * var element = editor.document.createElement( 'div' );
793 * editor.insertElement( element );
794 * var widget = editor.widgets.initOn( element, 'simplebox' );
