 121 The name of a Component property which references an element to add a listener to.</p>
 122
 123 <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
 124 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
 125 <pre><code>new Ext.panel.Panel({
 126     title: 'The title',
 127     listeners: {
 128         click: this.handlePanelClick,
 129         element: 'body'
 130     }
 131 });
 132 </code></pre></p>
 133
 134
 135 <p>When added in this way, the options available are the options applicable to <a href="Ext.core.Element.html#addListener" rel="Ext.core.Element#addListener" class="docClass">Ext.core.Element.addListener</a></p>

 139 </ul><br></p>
 140
 141 <p>
 142 <b>Combining Options</b><br>
 143 Using the options argument, it is possible to combine different types of listeners:<br>
 144 <br>
 145 A delayed, one-time listener.
 146 <pre><code>myPanel.on('hide', this.handleClick, this, {
 147 single: true,
 148 delay: 100
 149 });</code></pre>
 150 <p>
 151 <b>Attaching multiple handlers in 1 call</b><br>
 152 The method also allows for a single argument to be passed which is a config object containing properties
 153 which specify multiple events. For example:
 154 <pre><code>myGridPanel.on({
 155     cellClick: this.onCellClick,
 156     mouseover: this.onMouseOver,
 157     mouseout: this.onMouseOut,
 158     scope: this // Important. Ensure "this" is correct during handler execution
 159 });
