Setting the base color on an FxRadioButton control in Flex Gumbo

The following example shows how you can set the base color on a Flex Gumbo FxRadioButton control by setting the baseColor style.

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″.

<Application name="FxRadioButton_baseColor_test"

        verticalAlign="middle"
        backgroundColor="white">

    <FxRadioButtonGroup id="gr1" />

    <ApplicationControlBar dock="true">
        <Form styleName="plain">
            <FormItem label="baseColor:">
                <ColorPicker id="colorPicker"
                        selectedColor="#CCCCCC" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <VGroup>
        <FxRadioButton label="One"
                group="{gr1}"
                baseColor="{colorPicker.selectedColor}" />
        <FxRadioButton label="Two"
                group="{gr1}"
                baseColor="{colorPicker.selectedColor}" />
        <FxRadioButton label="Three"
                group="{gr1}"
                baseColor="{colorPicker.selectedColor}" />
        <FxRadioButton label="Four"
                group="{gr1}"
                baseColor="{colorPicker.selectedColor}" />
        <FxRadioButton label="Five"
                group="{gr1}"
                baseColor="{colorPicker.selectedColor}" />
    </VGroup>

</Application>

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

<Application name="FxRadioButton_baseColor_test"
        xmlns="http://ns.adobe.com/mxml/2009"
        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <Style>
        FxRadioButton {
            baseColor: haloBlue;
        }
    </Style>

    <FxRadioButtonGroup id="gr1" />

    <VGroup>
        <FxRadioButton label="One"
                group="{gr1}" />
        <FxRadioButton label="Two"
                group="{gr1}" />
        <FxRadioButton label="Three"
                group="{gr1}" />
        <FxRadioButton label="Four"
                group="{gr1}" />
        <FxRadioButton label="Five"
                group="{gr1}" />
    </VGroup>

</Application>

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

        layout="vertical"
        verticalAlign="middle"
        backgroundColor="white">

    <Script>
        <![CDATA[
            import mx.events.ColorPickerEvent;

            private function colorPicker_change(evt:ColorPickerEvent):void {
                radioButton1.setStyle("baseColor", evt.color);
                radioButton2.setStyle("baseColor", evt.color);
                radioButton3.setStyle("baseColor", evt.color);
                radioButton4.setStyle("baseColor", evt.color);
                radioButton5.setStyle("baseColor", evt.color);
            }
        ]]>
    </Script>

    <FxRadioButtonGroup id="gr1" />

    <ApplicationControlBar dock="true">
        <Form styleName="plain">
            <FormItem label="baseColor:">
                <ColorPicker id="colorPicker"
                        selectedColor="#CCCCCC"
                        change="colorPicker_change(event);" />
            </FormItem>
        </Form>
    </ApplicationControlBar>

    <VGroup>
        <FxRadioButton id="radioButton1"
                label="One"
                group="{gr1}" />
        <FxRadioButton id="radioButton2"
                label="Two"
                group="{gr1}" />
        <FxRadioButton id="radioButton3"
                label="Three"
                group="{gr1}" />
        <FxRadioButton id="radioButton4"
                label="Four"
                group="{gr1}" />
        <FxRadioButton id="radioButton5"
                label="Five"
                group="{gr1}" />
    </VGroup>

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.
