- * <b>Combining Options</b><br>
- * Using the options argument, it is possible to combine different types of listeners:<br>
- * <br>
+ *
+ * @param {String} eventName The name of the event to listen for. May also be an object who's property names are
+ * event names.
+ * @param {Function} handler The method the event invokes. Will be called with arguments given to
+ * {@link #fireEvent} plus the `options` parameter described below.
+ * @param {Object} scope (optional) The scope (`this` reference) in which the handler function is executed. **If
+ * omitted, defaults to the object which fired the event.**
+ * @param {Object} options (optional) An object containing handler configuration.
+ *
+ * **Note:** Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.
+ *
+ * This object may contain any of the following properties:
+ *
+ * - **scope** : Object
+ *
+ * The scope (`this` reference) in which the handler function is executed. **If omitted, defaults to the object
+ * which fired the event.**
+ *
+ * - **delay** : Number
+ *
+ * The number of milliseconds to delay the invocation of the handler after the event fires.
+ *
+ * - **single** : Boolean
+ *
+ * True to add a handler to handle just the next firing of the event, and then remove itself.
+ *
+ * - **buffer** : Number
+ *
+ * Causes the handler to be scheduled to run in an {@link Ext.util.DelayedTask} delayed by the specified number of
+ * milliseconds. If the event fires again within that time, the original handler is _not_ invoked, but the new
+ * handler is scheduled in its place.
+ *
+ * - **target** : Observable
+ *
+ * Only call the handler if the event was fired on the target Observable, _not_ if the event was bubbled up from a
+ * child Observable.
+ *
+ * - **element** : String
+ *
+ * **This option is only valid for listeners bound to {@link Ext.Component Components}.** The name of a Component
+ * property which references an element to add a listener to.
+ *
+ * This option is useful during Component construction to add DOM event listeners to elements of
+ * {@link Ext.Component Components} which will exist only after the Component is rendered.
+ * For example, to add a click listener to a Panel's body:
+ *
+ * new Ext.panel.Panel({
+ * title: 'The title',
+ * listeners: {
+ * click: this.handlePanelClick,
+ * element: 'body'
+ * }
+ * });
+ *
+ * **Combining Options**
+ *
+ * Using the options argument, it is possible to combine different types of listeners:
+ *
* A delayed, one-time listener.
- * <pre><code>
-myPanel.on('hide', this.handleClick, this, {
-single: true,
-delay: 100
-});</code></pre>
- * <p>
- * <b>Attaching multiple handlers in 1 call</b><br>
- * The method also allows for a single argument to be passed which is a config object containing properties
- * which specify multiple events. For example:<pre><code>
-myGridPanel.on({
- cellClick: this.onCellClick,
- mouseover: this.onMouseOver,
- mouseout: this.onMouseOut,
- scope: this // Important. Ensure "this" is correct during handler execution
-});
-</code></pre>.
- * <p>
+ *
+ * myPanel.on('hide', this.handleClick, this, {
+ * single: true,
+ * delay: 100
+ * });
+ *
+ * **Attaching multiple handlers in 1 call**
+ *
+ * The method also allows for a single argument to be passed which is a config object containing properties which
+ * specify multiple events. For example:
+ *
+ * myGridPanel.on({
+ * cellClick: this.onCellClick,
+ * mouseover: this.onMouseOver,
+ * mouseout: this.onMouseOut,
+ * scope: this // Important. Ensure "this" is correct during handler execution
+ * });
+ *
+ * One can also specify options for each event handler separately:
+ *
+ * myGridPanel.on({
+ * cellClick: {fn: this.onCellClick, scope: this, single: true},
+ * mouseover: {fn: panel.onMouseOver, scope: panel}
