Flex Examples

The following example shows how you can embed an icon in the Flex LinkButton control by setting the icon style.

Full code after the jump.

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/03/setting-the-icon-on-a-linkbutton-control-in-flex/ -->
<mx:Application name="LinkButton_icon_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:LinkButton id="linkButton"
            label="LinkButton"
            icon="@Embed('assets/LinkButton.png')" />

</mx:Application>

View source is enabled in the following example.

You can also embed the icon in an external .CSS file or <mx:Style /> block, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/03/setting-the-icon-on-a-linkbutton-control-in-flex/ -->
<mx:Application name="LinkButton_icon_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        LinkButton {
            icon: Embed("assets/LinkButton.png");
        }
    </mx:Style>

    <mx:LinkButton id="linkButton"
            label="LinkButton" />

</mx:Application>

Or, you can embed the icon in ActionScript and use data binding to bind the icon to the LinkButton control, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/03/setting-the-icon-on-a-linkbutton-control-in-flex/ -->
<mx:Application name="LinkButton_icon_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Script>
        <![CDATA[
            [Embed("assets/LinkButton.png")]
            private const linkButtonIcon:Class;
        ]]>
    </mx:Script>

    <mx:LinkButton id="linkButton"
            label="LinkButton"
            icon="{linkButtonIcon}" />

</mx:Application>

Due to popular demand, here is the “same” example in a more ActionScript friendly format:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/03/setting-the-icon-on-a-linkbutton-control-in-flex/ -->
<mx:Application name="LinkButton_icon_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white"
        initialize="init();">

    <mx:Script>
        <![CDATA[
            import mx.controls.LinkButton;

            [Embed("assets/LinkButton.png")]
            private const linkButtonIcon:Class;

            private var linkButton:LinkButton;

            private function init():void {
                linkButton = new LinkButton();
                linkButton.label = "LinkButton";
                linkButton.setStyle("icon", linkButtonIcon);
                addChild(linkButton);
            }
        ]]>
    </mx:Script>

</mx:Application>
