 147 The name of a Component property which references an element to add a listener to.</p>
 148
 149 <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
 150 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
 151 <pre><code>new Ext.panel.Panel({
 152     title: 'The title',
 153     listeners: {
 154         click: this.handlePanelClick,
 155         element: 'body'
 156     }
 157 });
 158 </code></pre></p>
 159
 160
 161 <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>
 162
 163
 164 <p></div></li>
 165 </ul><br></p>
 166
 167 <p>
 168 <b>Combining Options</b><br>
 169 Using the options argument, it is possible to combine different types of listeners:<br>
 170 <br>
 171 A delayed, one-time listener.
 172 <pre><code>myPanel.on('hide', this.handleClick, this, {
 173 single: true,
 174 delay: 100
 175 });</code></pre>
 176 <p>
 177 <b>Attaching multiple handlers in 1 call</b><br>
 178 The method also allows for a single argument to be passed which is a config object containing properties
 179 which specify multiple events. For example:
 180 <pre><code>myGridPanel.on({
 181     cellClick: this.onCellClick,
 182     mouseover: this.onMouseOver,
 183     mouseout: this.onMouseOut,
 184     scope: this // Important. Ensure "this" is correct during handler execution
 185 });
