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.

</s:Application>

You can also set the icon 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/2009/10/29/creating-an-mxml-based-icon-for-the-halo-linkbutton-control-in-flex-4/ -->
<s:Application name="Halo_LinkButton_icon_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">
 
    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
        @namespace mx "library://ns.adobe.com/flex/halo";
 
        mx|LinkButton {
            icon: ClassReference("ico");
        }
    </fx:Style>
 
    <fx:Declarations>
        <fx:Component className="ico">
            <s:Graphic>
                <s:states>
                    <s:State name="up" />
                    <s:State name="over" />
                    <s:State name="down" />
                </s:states>
                <s:Ellipse  width="8" height="8">
                    <s:fill>
                        <s:SolidColor color="red" color.over="green" color.down="blue" />
                    </s:fill>
                </s:Ellipse>
            </s:Graphic>
        </fx:Component>
    </fx:Declarations>
 
    <mx:LinkButton id="lnkBtn"
            label="Halo LinkButton"
            horizontalCenter="0" verticalCenter="0" />
 
</s:Application>

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

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

        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:controlBarContent>
        <s:Button id="btn"
                label="Set icon"
                click="btn_clickHandler(event);" />
    </s:controlBarContent>
 
    <fx:Script>
        <![CDATA[
            protected function btn_clickHandler(evt:MouseEvent):void {
                lnkBtn.setStyle("icon", ico);
            }
        ]]>
    </fx:Script>
 
    <fx:Declarations>
        <fx:Component className="ico">
            <s:Graphic>
                <s:states>
                    <s:State name="up" />
                    <s:State name="over" />
                    <s:State name="down" />
                </s:states>
                <s:Ellipse  width="8" height="8">
                    <s:fill>
                        <s:SolidColor color="red" color.over="green" color.down="blue" />
                    </s:fill>
                </s:Ellipse>
            </s:Graphic>
        </fx:Component>
    </fx:Declarations>
 
    <mx:LinkButton id="lnkBtn"

            horizontalCenter="0" verticalCenter="0" />
 
</s:Application>
