    <p>First of all add two <em>states</em> to your application:</p> <pre class="lang-js prettyprint-override"><code>&lt;s:states&gt; &lt;s:State name="portrait"/&gt; &lt;s:State name="landscape"/&gt; &lt;/s:states&gt; </code></pre> <p>Next, add the following function to your <code>&lt;fx:Script&gt;</code> section:</p> <pre class="lang-js prettyprint-override"><code>&lt;fx:Script&gt; &lt;![CDATA[ import mx.events.ResizeEvent; protected function application1_resizeHandler(event:ResizeEvent):void { if (width&gt;height) this.currentState="landscape"; else this.currentState="portrait"; } ]]&gt; &lt;/fx:Script&gt; </code></pre> <p>Also call the method above on application <em>resize</em>:</p> <pre class="lang-js prettyprint-override"><code>&lt;s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" applicationDPI="160" resize="application1_resizeHandler(event)"&gt; </code></pre> <p>Now if you want to include or exclude a component just add <em>visible</em> or <em>includeIn</em> on the desired component:</p> <pre class="lang-js prettyprint-override"><code>visible.landscape="false" </code></pre> <p>or</p> <pre class="lang-js prettyprint-override"><code>includeIn="landscape" </code></pre> <p>Full code sample:</p> <pre class="lang-js prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" resize="application1_resizeHandler(event)"&gt; &lt;fx:Declarations&gt; &lt;!-- Place non-visual elements (e.g., services, value objects) here --&gt; &lt;/fx:Declarations&gt; &lt;s:states&gt; &lt;s:State name="portrait"/&gt; &lt;s:State name="landscape"/&gt; &lt;/s:states&gt; &lt;fx:Script&gt; &lt;![CDATA[ import mx.events.ResizeEvent; protected function application1_resizeHandler(event:ResizeEvent):void { if (width&gt;height) this.currentState="landscape"; else this.currentState="portrait"; } ]]&gt; &lt;/fx:Script&gt; &lt;s:Button includeIn="landscape" x="58" y="52" label="Landscape"/&gt; &lt;s:Button includeIn="portrait" x="58" y="90" label="Portrait"/&gt; &lt;/s:WindowedApplication&gt; </code></pre>

    1. COOk that might be the best method to do this. But I would have thought that there could be better solutions since everyone tells you, that for performance reasons includeIn/excludeIn is better than setting visible=false and includeInLayout=false, because objects don't need to be created. And the includeIn/excludeIn are afaik only available with states..

    2. COYou are right, but with the above code you do have states and therfor you are able to use `includeIn/excludeIn`. Please see the full code sample above.

    3. COYeah but I want to access the Applications states in my view component not in my application component. Please see my question.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
