 103 <li><strong>angle</strong> - number, optional - The angle of the gradient in degrees.</li>

 209 The name of a Component property which references an element to add a listener to.</p>
 210
 211 <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
 212 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

 214     title: 'The title',
 215     listeners: {
 216         click: this.handlePanelClick,
 217         element: 'body'

 230 <b>Combining Options</b><br>
 231 Using the options argument, it is possible to combine different types of listeners:<br>
 232 <br>
 233 A delayed, one-time listener.
 234 <pre><code>myPanel.on('hide', this.handleClick, this, {
 235 single: true,
 236 delay: 100
 237 });</code></pre>

 239 <b>Attaching multiple handlers in 1 call</b><br>
 240 The method also allows for a single argument to be passed which is a config object containing properties
 241 which specify multiple events. For example:
 242 <pre><code>myGridPanel.on({
 243     cellClick: this.onCellClick,
 244     mouseover: this.onMouseOver,
 245     mouseout: this.onMouseOut,
 246     scope: this // Important. Ensure "this" is correct during handler execution
 247 });
