 139 The name of a Component property which references an element to add a listener to.</p>
 140
 141 <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
 142 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
 143 <pre><code>new Ext.panel.Panel({
 144     title: 'The title',
 145     listeners: {
 146         click: this.handlePanelClick,
 147         element: 'body'
 148     }
 149 });
 150 </code></pre></p>
 151
 152
 153 <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>

 157 </ul><br></p>
 158
 159 <p>
 160 <b>Combining Options</b><br>
 161 Using the options argument, it is possible to combine different types of listeners:<br>
 162 <br>
 163 A delayed, one-time listener.
 164 <pre><code>myPanel.on('hide', this.handleClick, this, {
 165 single: true,
 166 delay: 100
 167 });</code></pre>
 168 <p>
 169 <b>Attaching multiple handlers in 1 call</b><br>
 170 The method also allows for a single argument to be passed which is a config object containing properties
 171 which specify multiple events. For example:
 172 <pre><code>myGridPanel.on({
 173     cellClick: this.onCellClick,
 174     mouseover: this.onMouseOver,
 175     mouseout: this.onMouseOut,
 176     scope: this // Important. Ensure "this" is correct during handler execution
 177 });
