The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see http://www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.
For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

    <s:RichEditableText id="sdkVer"

            width="100%"
            initialize="sdkVer.text = mx_internal::VERSION;" />
 
</s:Application>

The custom skin class, skins/CustomApplicationSkin.mxml, is as follows:

View skins/CustomApplicationSkin.mxml

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2009/03/22/setting-a-background-image-on-an-fxapplication-in-flex-gumbo/ -->

        alpha.disabled="0.5" >

        <s:State name="normal" />
        <s:State name="disabled" />
    </s:states>

    <![CDATA[ 
        [HostComponent("spark.components.Application")]
    ]]>
    </fx:Metadata> 
 
    <!-- fill -->
    <s:BitmapImage id="img"
            source="@Embed('image1.jpg')"
            resizeMode="scale"
            smooth="true"
            left="0" right="0"
            top="0" bottom="0" />
 
    <s:Group id="contentGroup" left="0" right="0" top="0" bottom="0" minWidth="0" minHeight="0" />
 
</s:Skin>

You can also set the skinClass style in an external .CSS file or <Style/> block, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2009/03/22/setting-a-background-image-on-an-fxapplication-in-flex-gumbo/ -->
<s:Application name="Spark_Application_skinClass_test"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/halo">
    <s:layout>
        <s:BasicLayout />
    </s:layout>
 
    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
 
        s|Application {
            skinClass: ClassReference("skins.CustomApplicationSkin");
        }
    </fx:Style>
 
    <s:RichEditableText id="sdkVer"
            editable="false"
            textAlign="center"
            fontSize="72"
            horizontalCenter="0"
            verticalCenter="0"
            width="100%"
            initialize="sdkVer.text = mx_internal::VERSION;" />
 
</s:Application>

Or, you can set the skinClass style using ActionScript, as seen in the following example:

<?xml version="1.0" encoding="utf-8"?>

        xmlns:mx="library://ns.adobe.com/flex/halo">
    <s:layout>
        <s:BasicLayout />
    </s:layout>
 
    <fx:Script>
        <![CDATA[
            import skins.CustomApplicationSkin;
 
            protected function btn_click(evt:MouseEvent):void {
                setStyle("skinClass", CustomApplicationSkin);
            }
        ]]>
    </fx:Script>
 
    <s:Button id="btn"
            label="Set skin class"
            click="btn_click(event);"
            x="10"
            y="10" />
 
    <s:RichEditableText id="sdkVer"
            editable="false"
            textAlign="center"
            fontSize="72"
            horizontalCenter="0"
            verticalCenter="0"
            width="100%"
            initialize="sdkVer.text = mx_internal::VERSION;" />
 
</s:Application>

This entry is based on a beta version of the Flex 4 SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex 4 SDK.
