|
|
* to the editor, which in classic (`iframe`-based) editor happens every time the
|
|
* data or the mode is set. This listener will also be removed when that editable is detached.
|
|
*
|
|
* It is also possible to attach a listener to another object (e.g. to a document).
|

*
|
|
* editor.on( 'contentDom', function() {

|
|
* which inherits from {@link CKEDITOR.event} may be used including {@link CKEDITOR.dom.element},
|
|
* {@link CKEDITOR.dom.document}, and {@link CKEDITOR.editable}.
|
|
* @param {String} eventName The name of the event that will be listened to.
|
|
* @param {Function} listenerFunction The function listening to the
|
|
* event. A single {@link CKEDITOR.eventInfo} object instance
|
|
* containing all the event data is passed to this function.
|
|
* @param {Object} [scopeObj] The object used to scope the listener
|
|
* call (the `this` object). If omitted, the current object is used.
|
|
* @param {Object} [listenerData] Data to be sent as the
|
|
* {@link CKEDITOR.eventInfo#listenerData} when calling the listener.
|
|
* @param {Number} [priority=10] The listener priority. Lower priority
|
|
* listeners are called first. Listeners with the same priority
|
|
* value are called in the registration order.
