<mx:Application name="HDividedBox_dividerSkin_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:HDividedBox id="dividedBox"
            dividerSkin="@Embed('assets/DividedBox.png')"
            horizontalGap="24"
            width="100%"
            height="100%">
        <mx:Box id="box1"
                backgroundColor="haloGreen"
                width="100%"
                height="100%"
                minWidth="100" />
        <mx:Box id="box2"
                backgroundColor="haloBlue"
                width="100%"
                height="100%"
                minWidth="100" />
    </mx:HDividedBox>

</mx:Application>

View source is enabled in the following example.

You can also set the dividerSkin style 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/2008/09/18/customizing-the-divider-skin-on-a-dividedbox-container-in-flex/ -->
<mx:Application name="HDividedBox_dividerSkin_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <mx:Style>
        HDividedBox {
            dividerSkin: Embed("assets/DividedBox.png");
            horizontalGap: 24;
        }
    </mx:Style>

    <mx:HDividedBox id="dividedBox"
            width="100%"
            height="100%">
        <mx:Box id="box1"
                backgroundColor="haloGreen"
                width="100%"
                height="100%"
                minWidth="100" />
        <mx:Box id="box2"
                backgroundColor="haloBlue"
                width="100%"
                height="100%"
                minWidth="100" />
    </mx:HDividedBox>

</mx:Application>

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

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/09/18/customizing-the-divider-skin-on-a-dividedbox-container-in-flex/ -->
<mx:Application name="HDividedBox_dividerSkin_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white"
        initialize="init();">

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

            private function init():void {
                dividedBox.setStyle("dividerSkin", customDividerSkin);
            }
        ]]>
    </mx:Script>

    <mx:HDividedBox id="dividedBox"
            horizontalGap="24"
            width="100%"
            height="100%">
        <mx:Box id="box1"
                backgroundColor="haloGreen"
                width="100%"
                height="100%"
                minWidth="100" />
        <mx:Box id="box2"
                backgroundColor="haloBlue"
                width="100%"
                height="100%"
                minWidth="100" />
    </mx:HDividedBox>

</mx:Application>

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

        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white"
        initialize="init();">

    <mx:Script>
        <![CDATA[
            import mx.containers.Box;
            import mx.containers.HDividedBox;

            [Embed("assets/DividedBox.png")]
            private const customDividerSkin:Class;

            private var dividedBox:HDividedBox;
            private var box1:Box;
            private var box2:Box;

            private function init():void {
                box1 = new Box();
                box1.percentWidth = 100;
                box1.percentHeight = 100;
                box1.minWidth = 100;
                box1.setStyle("backgroundColor", "haloGreen");

                box2 = new Box();
                box2.percentWidth = 100;
                box2.percentHeight = 100;
                box2.minWidth = 100;
                box2.setStyle("backgroundColor", "haloBlue");

                dividedBox = new HDividedBox();
                dividedBox.percentWidth = 100;
                dividedBox.percentHeight = 100;
                dividedBox.setStyle("dividerSkin", customDividerSkin);
                dividedBox.setStyle("horizontalGap", 24);
                dividedBox.addChild(box1);
                dividedBox.addChild(box2);
                addChild(dividedBox);
            }
        ]]>
    </mx:Script>

</mx:Application>
