  38 Represents a collection of a set of key and value pairs. Each key in the MixedCollection
  39 must be unique, the same key cannot exist twice. This collection is ordered, items in the
  40 collection can be accessed by index  or via the key. Newly added items are added to
  41 the end of the collection. This class is similar to <a href="Ext.util.HashMap.html" rel="Ext.util.HashMap" class="docClass">Ext.util.HashMap</a> however it
  42 is heavier and provides more functionality. Sample usage:
  43 <pre class="prettyprint"><code>var coll = new Ext.util.MixedCollection();
  44 coll.add('key1', 'val1');
  45 coll.add('key2', 'val2');

  47
  48 console.log(coll.get('key1')); // prints 'val1'
  49 console.log(coll.indexOfKey('key3')); // prints 2
  50 </code></pre>
  51
  52 <p>
  53 The MixedCollection also has support for sorting and filtering of the values in the collection.
  54 <pre class="prettyprint"><code>var coll = new Ext.util.MixedCollection();
  55 coll.add('key1', 100);

  58 coll.add('key4', 0);
  59 var biggerThanZero = coll.filterBy(function(value){

 184 The name of a Component property which references an element to add a listener to.</p>
 185

 205 <b>Combining Options</b><br>
 206 Using the options argument, it is possible to combine different types of listeners:<br>
 207 <br>
 208 A delayed, one-time listener.
 209 <pre><code>myPanel.on('hide', this.handleClick, this, {
 210 single: true,
 211 delay: 100
 212 });</code></pre>
 213 <p>
 214 <b>Attaching multiple handlers in 1 call</b><br>
 215 The method also allows for a single argument to be passed which is a config object containing properties
 216 which specify multiple events. For example:
 217 <pre><code>myGridPanel.on({
 218     cellClick: this.onCellClick,
 219     mouseover: this.onMouseOver,
 220     mouseout: this.onMouseOut,
 221     scope: this // Important. Ensure "this" is correct during handler execution
 222 });
