116 | * Registers an event listener that needs to be removed when detaching this editable. | |
117 | * This means that it will be automatically removed when {@link #detach} is executed, | |
118 | * for example on {@link CKEDITOR.editor#setMode changing editor mode} or destroying editor. | |
119 | * | |
120 | * Except for `obj` all other arguments have the same meaning as in {@link CKEDITOR.event#on}. | |
121 | * | |
122 | * This method is strongly related to the {@link CKEDITOR.editor#contentDom} and | |
123 | * {@link CKEDITOR.editor#contentDomUnload} events, because they are fired | |
124 | * when an editable is being attached and detached. Therefore, this method is usually used | |
125 | * in the following way: | |
126 | * | |
127 | * editor.on( 'contentDom', function() { | |
128 | * var editable = editor.editable(); | |
129 | * editable.attachListener( editable, 'mousedown', function() { | |
130 | * // ... | |
131 | * } ); | |
132 | * } ); | |
133 | * | |
134 | * This code will attach the `mousedown` listener every time a new editable is attached | |
135 | * to the editor, which in classic (`iframe`-based) editor happens every time the | |
136 | * data or the mode is set. This listener will also be removed when that editable is detached. | |
137 | * | |
138 | * It is also possible to attach a listener to another object (e.g. to a document). | |
139 | * | |
140 | * editor.on( 'contentDom', function() { | |
141 | * editor.editable().attachListener( editor.document, 'mousedown', function() { | |
142 | * // ... | |
143 | * } ); | |
144 | * } ); | |
145 | * | |
146 | * @param {CKEDITOR.event} obj The element/object to which the listener will be attached. Every object | |
147 | * which inherits from {@link CKEDITOR.event} may be used including {@link CKEDITOR.dom.element}, | |
148 | * {@link CKEDITOR.dom.document}, and {@link CKEDITOR.editable}. | |
149 | * @param {String} eventName The name of the event that will be listened to. | |
150 | * @param {Function} listenerFunction The function listening to the | |
151 | * event. A single {@link CKEDITOR.eventInfo} object instance | |
152 | * containing all the event data is passed to this function. | |
153 | * @param {Object} [scopeObj] The object used to scope the listener | |
154 | * call (the `this` object). If omitted, the current object is used. | |
155 | * @param {Object} [listenerData] Data to be sent as the | |
156 | * {@link CKEDITOR.eventInfo#listenerData} when calling the listener. | |
157 | * @param {Number} [priority=10] The listener priority. Lower priority | |
158 | * listeners are called first. Listeners with the same priority | |
159 | * value are called in the registration order. | |
