<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
+A delayed, one-time listener.
+<pre><code>myDataView.on(<em>'click'</em>, this.onClick, 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 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>
- }
+<pre><code>myGridPanel.on({
+<em>'click'</em> : {
+ fn: this.onClick,
+ scope: this,
+ delay: 100
+},
+<em>'mouseover'</em> : {
+ fn: this.onMouseOver,
+ scope: this
+},
+<em>'mouseout'</em> : {
+ fn: this.onMouseOut,
+ scope: this

});</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,
