-The name of a Component property which references an element to add a listener to.</p>
-
-<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({
- title: 'The title',
- listeners: {
- click: this.handlePanelClick,
- element: 'body'
- }
-});
-</code></pre></p>
-
-
-<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>
-
-
-<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
-});
-</code></pre>.
