    <p>As already said, you have to learn to uses the different layouts. See this <a href="http://docs.sencha.com/extjs/4.2.0/#!/example/layout-browser/layout-browser.html" rel="nofollow">demo</a> to get an idea of what's available.</p> <p>Now, regarding the structure of the doc, 'configs', 'methods', 'properties', and 'events' are really three different concepts, but only config is specific to Ext. The others are general object oriented concepts.</p> <p>In a nutshell:</p> <ul> <li><p>Properties are the variables that are bound to on object. In the context of Ext, they are almost always read-only. That don't means that you can't change their value (impossible to prevent in Javascript), but that <strong>you shouldn't</strong>. So you use poperties to read information from existing objects. For example:</p> <pre><code>if (checkbox.checked) { ... } </code></pre></li> <li><p>Config options are the option that you can use when you create an object. Almost all constructors in Ext accept one single argument, an object called the config object. So you use config options when you create an object:</p> <pre><code>Ext.create('Ext.window.Window', { width: 200, height: 200, ... }); </code></pre></li> <li><p>Methods is the name given to functions that belongs to an object. Unlike properties, when you use a method, code is running, so that's what you use for doing things.</p> <pre><code>window.show(); // using the animate parameter window.show(true); </code></pre></li> <li><p>Events are things that happen in the application. You can react to them by <a href="http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.util.Observable-method-addListener" rel="nofollow">attaching listeners</a> (also named callback functions) to them. The parameters that are given for events in the doc are the one that will be passed your callback method.</p> <pre><code>// E.g. displaying an alert when a button is clicked button.addListener( // name of the event 'click', // the callback function function() { alert('Clicked!'); } ) </code></pre></li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
