+
+<p>This option is useful during Component construction to add DOM event listeners to elements of <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a> which
+will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
+<pre><code>new Ext.panel.Panel({

+ listeners: {
+ click: this.handlePanelClick,
+ element: 'body'
+ }

+
+
+<p></div></li>
+</ul><br></p>
+
+<p>
+<b>Combining Options</b><br>
+Using the options argument, it is possible to combine different types of listeners:<br>
+<br>
+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
