<strong>Parameters:</strong>
<ul><li><code>eventName</code> : String<div class="sub-desc">The type of event to listen for</div></li><li><code>handler</code> : Function<div class="sub-desc">The method the event invokes</div></li><li><code>scope</code> : Object<div class="sub-desc">(optional) The scope in which to execute the handler
function. The handler function's "this" context.</div></li><li><code>options</code> : Object<div class="sub-desc">(optional) An object containing handler configuration
properties. This may contain any of the following properties:<ul>
<li><b>scope</b> : Object<p class="sub-desc">The scope in which to execute the handler function. The handler function's "this" context.</p></li>
<li><b>delay</b> : Number<p class="sub-desc">The number of milliseconds to delay the invocation of the handler after the event fires.</p></li>
<li><b>single</b> : Boolean<p class="sub-desc">True to add a handler to handle just the next firing of the event, and then remove itself.</p></li>
<li><b>buffer</b> : Number<p class="sub-desc">Causes the handler to be scheduled to run in an <a ext:cls="Ext.util.DelayedTask" href="output/Ext.util.DelayedTask.html">Ext.util.DelayedTask</a> delayed

handler is <em>not</em> invoked, but the new handler is scheduled in its place.</p></li>
</ul><br>
<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
single: true,
delay: 100,
forumId: 4
});</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 handlers.
<p>
<pre><code>foo.on({
<em>'click'</em> : {
fn: <b>this</b>.onClick,
scope: <b>this</b>,
delay: 100
},
<em>'mouseover'</em> : {
fn: <b>this</b>.onMouseOver,
scope: <b>this</b>
},
<em>'mouseout'</em> : {
fn: <b>this</b>.onMouseOut,
scope: <b>this</b>
}
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>foo.on({
<em>'click'</em> : <b>this</b>.onClick,
<em>'mouseover'</em> : <b>this</b>.onMouseOver,
<em>'mouseout'</em> : <b>this</b>.onMouseOut,
scope: <b>this</b>
