|
|
*
|
|
* Note that neither the repository nor the widget instances can be created by using their constructors.
|
|
* A repository instance is automatically set up by the Widget plugin and is accessible under
|
|
* {@link CKEDITOR.editor#widgets}, while widget instances are created and destroyed by the repository.
|
|
*
|
|
* To create a widget, first you need to {@link CKEDITOR.plugins.widget.repository#add register} its
|
|
* {@link CKEDITOR.plugins.widget.definition definition}:
|
|
*
|
|
* editor.widgets.add( 'simplebox', {

* upcast: function( element ) {

|
* init: function() {
|
|
* // ...
|
|
* }
|
|
* } );
|
|
*
|
|
* Once the widget definition is registered, widgets will be automatically
|
|
* created when loading data:
|
|
*
|
|
* editor.setData( '<div class="simplebox">foo</div>', function() {
|
|
* console.log( editor.widgets.instances ); // -> An object containing one instance.
|
|
* } );
|
|
*
|
|
* It is also possible to create instances during runtime by using a command
|
|
* (if a {@link CKEDITOR.plugins.widget.definition#template} property was defined):
|
|
*
|
|
* // You can execute an automatically defined command to
|
|
* // insert a new simplebox widget or edit the one currently focused.
|
|
* editor.execCommand( 'simplebox' );
|

*
|
|
* Note: Since CKEditor 4.5 widget's `startupData` can be passed as the command argument:
|
|
*
|
|
* editor.execCommand( 'simplebox', {
|
|
* startupData: {
|
|
* align: 'left'
|
|
* }
|
|
* } );
|
|
*
|
|
* A widget can also be created in a completely custom way:
|
|
*
|
|
* var element = editor.document.createElement( 'div' );
|
|
* editor.insertElement( element );
|
