  38
  39
  40
  41
  42 <p>Ext.Direct aims to streamline communication between the client and server
  43 by providing a single interface that reduces the amount of common code
  44 typically required to validate data and handle returned data packets
  45 (reading data, error conditions, etc).</p>
  46
  47
  48
  49
  50 <p>The Ext.direct namespace includes several classes for a closer integration
  51 with the server-side. The Ext.data namespace also includes classes for working
  52 with Ext.data.Stores which are backed by data from an Ext.Direct method.</p>

  68 <p><b><u>Providers</u></b></p>
  69
  70
  71
  72
  73 <p>Ext.Direct uses a provider architecture, where one or more providers are
  74 used to transport data to and from the server. There are several providers
  75 that exist in the core at the moment:</p>
  76
  77
  78 <div class="mdetail-params"><ul>
  79
  80 <li><a href="Ext.direct.JsonProvider.html" rel="Ext.direct.JsonProvider" class="docClass">JsonProvider</a> for simple JSON operations</li>
  81 <li><a href="Ext.direct.PollingProvider.html" rel="Ext.direct.PollingProvider" class="docClass">PollingProvider</a> for repeated requests</li>
  82 <li><a href="Ext.direct.RemotingProvider.html" rel="Ext.direct.RemotingProvider" class="docClass">RemotingProvider</a> exposes server side
  83 on the client.</li>
  84 </ul></div>
  85
  86
  87
  88
  89 <p>A provider does not need to be invoked directly, providers are added via
  90 <a href="Ext.direct.Manager.html" rel="Ext.direct.Manager" class="docClass">Ext.direct.Manager</a>.<a href="Ext.direct.Manager.html#add" rel="Ext.direct.Manager#add" class="docClass">add</a>.</p>
  91
  92
  93
  94
  95 <p><b><u>Router</u></b></p>
  96
  97
  98
  99
 100 <p>Ext.Direct utilizes a "router" on the server to direct requests from the client
 101 to the appropriate server-side method. Because the Ext.Direct API is completely
 102 platform-agnostic, you could completely swap out a Java based server solution
 103 and replace it with one that uses C# without changing the client side JavaScript
 104 at all.</p>
 105
 106
 107
 108
 109 <p><b><u>Server side events</u></b></p>
 110
 111
 112
 113
 114 <p>Custom events from the server may be handled by the client by adding
 115 listeners, for example:</p>
 116
 117
 118 <pre class="prettyprint"><code>{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
 119
 120 // add a handler for a 'message' event sent by the server
 121 Ext.direct.Manager.on('message', function(e){
 122     out.append(String.format('&lt;p>&lt;i>{0}&lt;/i>&lt;/p>', e.data));
 123             out.el.scrollTo('t', 100000, true);
 124 });
 125 </code></pre>

 140 events directly from a child element of a Component, we need to specify the <code>element</code> option to

 197 The name of a Component property which references an element to add a listener to.</p>
 198

 202     title: 'The title',
 203     listeners: {

 215 </ul><br></p>
 216
 217 <p>
 218 <b>Combining Options</b><br>
 219 Using the options argument, it is possible to combine different types of listeners:<br>
 220 <br>
 221 A delayed, one-time listener.
 222 <pre><code>myPanel.on('hide', this.handleClick, this, {

 225 });</code></pre>
 226 <p>
 227 <b>Attaching multiple handlers in 1 call</b><br>
 228 The method also allows for a single argument to be passed which is a config object containing properties
 229 which specify multiple events. For example:
 230 <pre><code>myGridPanel.on({
 231     cellClick: this.onCellClick,
 232     mouseover: this.onMouseOver,
 233     mouseout: this.onMouseOut,
