124 The name of a Component property which references an element to add a listener to.</p>
125
126 <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
127 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
128 <pre><code>new Ext.panel.Panel({
129     title: 'The title',
130     listeners: {
131         click: this.handlePanelClick,
132         element: 'body'
133     }
134 });
135 </code></pre></p>
136
137
138 <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>

141 <p></div></li>
142 </ul><br></p>
143
144 <p>
145 <b>Combining Options</b><br>
146 Using the options argument, it is possible to combine different types of listeners:<br>
147 <br>
148 A delayed, one-time listener.
149 <pre><code>myPanel.on('hide', this.handleClick, this, {
150 single: true,
151 delay: 100
152 });</code></pre>
153 <p>
154 <b>Attaching multiple handlers in 1 call</b><br>
155 The method also allows for a single argument to be passed which is a config object containing properties
156 which specify multiple events. For example:
157 <pre><code>myGridPanel.on({
158     cellClick: this.onCellClick,
159     mouseover: this.onMouseOver,
160     mouseout: this.onMouseOut,
161     scope: this // Important. Ensure "this" is correct during handler execution
162 });
