  38 see <a href="Ext.grid.feature.GroupingSummary.html" rel="Ext.grid.feature.GroupingSummary" class="docClass">Ext.grid.feature.GroupingSummary</a>. There are 2 aspects to calculating the summaries,
  39 calculation and rendering.</p>
  40
  41 <h2>Calculation</h2>
  42
  43 <p>The summary value needs to be calculated for each column in the grid. This is controlled
  44 by the summaryType option specified on the column. There are several built in summary types,
  45 which can be specified as a string on the column configuration. These call underlying methods
  46 on the store:</p>
  47
  48 <ul>
  49 <li><a href="Ext.data.Store.html#count" rel="Ext.data.Store#count" class="docClass">count</a></li>
  50 <li><a href="Ext.data.Store.html#sum" rel="Ext.data.Store#sum" class="docClass">sum</a></li>
  51 <li><a href="Ext.data.Store.html#min" rel="Ext.data.Store#min" class="docClass">min</a></li>
  52 <li><a href="Ext.data.Store.html#max" rel="Ext.data.Store#max" class="docClass">max</a></li>
  53 <li><a href="Ext.data.Store.html#average" rel="Ext.data.Store#average" class="docClass">average</a></li>
  54 </ul>
  55
  56
  57 <p>Alternatively, the summaryType can be a function definition. If this is the case,
  58 the function is called with an array of records to calculate the summary value.</p>
  59
  60 <h2>Rendering</h2>
  61
  62 <p>Similar to a column, the summary also supports a summaryRenderer function. This
  63 summaryRenderer is called before displaying a value. The function is optional, if
  64 not specified the default calculated value is shown. The summaryRenderer is called with:</p>
  65
  66 <ul>
  67 <li>value {Object} - The calculated value.</li>
  68 <li>data {Object} - Contains all raw summary values for the row.</li>
  69 <li>field {String} - The name of the field we are calculating</li>
  70 </ul>
  71

 208 The name of a Component property which references an element to add a listener to.</p>
 209
 210 <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
 211 will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
 212 <pre><code>new Ext.panel.Panel({
 213     title: 'The title',
 214     listeners: {
 215         click: this.handlePanelClick,
 216         element: 'body'
 217     }
 218 });
 219 </code></pre></p>
 220
 221
 222 <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>

 226 </ul><br></p>
 227
 228 <p>
 229 <b>Combining Options</b><br>
 230 Using the options argument, it is possible to combine different types of listeners:<br>
 231 <br>
 232 A delayed, one-time listener.
 233 <pre><code>myPanel.on('hide', this.handleClick, this, {
 234 single: true,
 235 delay: 100
 236 });</code></pre>
 237 <p>
 238 <b>Attaching multiple handlers in 1 call</b><br>
 239 The method also allows for a single argument to be passed which is a config object containing properties
 240 which specify multiple events. For example:
 241 <pre><code>myGridPanel.on({
 242     cellClick: this.onCellClick,
 243     mouseover: this.onMouseOver,
 244     mouseout: this.onMouseOut,
 245     scope: this // Important. Ensure "this" is correct during handler execution
 246 });
