The following example shows how you can set the minimum, maximum, and current value on a Flex Gumbo FxHScrollBar control by setting the minimum, maximum, and value properties.
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="FxHScrollBar_value_test"
xmlns="http://ns.adobe.com/mxml/2009"

verticalAlign="middle"

<ApplicationControlBar dock="true">
<Form styleName="plain">
<FormItem label="value:" direction="horizontal">
<FxHSlider id="slider"

maximum="100"
value="76"
liveDragging="true" />
<Label text="{hScrollBar.value}" />
</FormItem>
</Form>
</ApplicationControlBar>
<FxHScrollBar id="hScrollBar"
minimum="0"
maximum="100"
value="{slider.value}"
width="100" />
</Application>
You can also set the value property using ActionScript, as seen in the following example:

<Script>
<![CDATA[
import mx.events.SliderEvent;
private function slider_change(evt:Event):void {
hScrollBar.value = evt.currentTarget.value;
}
]]>
</Script>
<ApplicationControlBar dock="true">
<Form styleName="plain">
<FormItem label="value:" direction="horizontal">
<FxHSlider id="slider"
minimum="0"
maximum="100"
liveDragging="true"
change="slider_change(event);" />
<Label text="{hScrollBar.value}" />
</FormItem>
</Form>
</ApplicationControlBar>
<FxHScrollBar id="hScrollBar"
minimum="0"
maximum="100"
width="100" />
</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.
