Using the FxButtonBar control in Flex Gumbo

The following example shows how you can use the Flex Gumbo FxButtonBar by setting the dataProvider property to an ArrayCollection object.

Full code after the jump.

To use the following code, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3. For more information on downloading and installing the Gumbo SDK into Flex Builder 3, see “Using the beta Gumbo SDK in Flex Builder 3″.

        <Form styleName="plain">
            <FormItem label="selectedIndex:">
                <Label text="{btnBar.selectedIndex}" />
            </FormItem>
            <FormItem label="selectedItem:">
                <Label text="{ObjectUtil.toString(btnBar.selectedItem)}" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <FxButtonBar id="btnBar"
            dataProvider="{arrColl}" />

</Application>

View source is enabled in the following example.

You can also set the dataProvider property inline in MXML using the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2009/02/08/using-the-fxbuttonbar-control-in-flex-gumbo/ -->
<Application name="FxButtonBar_test"
        xmlns="http://ns.adobe.com/mxml/2009"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <Script>
        <![CDATA[
            import mx.utils.ObjectUtil;
        ]]>
    </Script>

    <ApplicationControlBar dock="true">
        <Form styleName="plain">
            <FormItem label="selectedIndex:">
                <Label text="{btnBar.selectedIndex}" />
            </FormItem>
            <FormItem label="selectedItem:">
                <Label text="{ObjectUtil.toString(btnBar.selectedItem)}" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <FxButtonBar id="btnBar">
        <dataProvider>
            <ArrayCollection source="[One,Two,Three,Four,Five]" />
        </dataProvider>
    </FxButtonBar>

</Application>

Or, you can set the dataProvider property using ActionScript, as seen in the following example:

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2009/02/08/using-the-fxbuttonbar-control-in-flex-gumbo/ -->
<Application name="FxButtonBar_test"
        xmlns="http://ns.adobe.com/mxml/2009"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <Script>
        <![CDATA[
            import mx.utils.ObjectUtil;
            import mx.collections.ArrayCollection;

            private var arrColl:ArrayCollection;

            private function init():void {
                var arr:Array = ["One", "Two", "Three", "Four", "Five"];
                arrColl = new ArrayCollection(arr);
                btnBar.dataProvider = arrColl;
            }
        ]]>
    </Script>

    <ApplicationControlBar dock="true">
        <Form styleName="plain">
            <FormItem label="selectedIndex:">
                <Label text="{btnBar.selectedIndex}" />
            </FormItem>
            <FormItem label="selectedItem:">
                <Label text="{ObjectUtil.toString(btnBar.selectedItem)}" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <FxButtonBar id="btnBar"
            initialize="init();" />

</Application>

This entry is based on a beta version of the Flex Gumbo 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 Gumbo SDK.
