Setting the slide duration on a Spark HSlider control in Flex 4

The following example shows how you can set the slide duration on a Spark HSlider control in Flex 4 by setting the slideDuration style.

Full code after the jump.

The following example(s) require Flash Player 10 and the Adobe Flex 4 SDK. To download the Adobe Flash Builder 4 trial, see www.adobe.com/products/flex/. To download the latest nightly build of the Flex 4 SDK, see opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.

For more information on getting started with Flex 4 and Flash Builder 4, see the official Adobe Flex Team blog.

            <mx:FormItem label="slideDuration:">
                <s:NumericStepper id="numericStepper"
                        minimum="0"
                        maximum="10000"
                        value="8000"
                        valueInterval="100" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <s:HSlider id="slider"
            liveDragging="true"
            slideDuration="{numericStepper.value}"
            horizontalCenter="0"
            verticalCenter="0"
            left="20"
            right="20" />

</s:Application>

View source is enabled in the following example.

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

View MXML

<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2009/05/28/setting-the-slide-duration-on-a-spark-hslider-control-in-flex-gumbo/ -->
<s:Application name="Spark_HSlider_slideDuration_test"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/halo">

    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";

        s|HSlider {
            slideDuration: 8000;
        }
    </fx:Style>

    <s:HSlider id="slider"
            liveDragging="true"
            horizontalCenter="0"
            verticalCenter="0"
            left="20"
            right="20" />

</s:Application>

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

View MXML

<?xml version="1.0" encoding="utf-8"?>

        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/halo">

    <fx:Script>
        <![CDATA[
            private function numericStepper_change(evt:Event):void {
                slider.setStyle("slideDuration", numericStepper.value);
            }
        ]]>
    </fx:Script>

    <mx:ApplicationControlBar width="100%" cornerRadius="0">
        <mx:Form styleName="plain">
            <mx:FormItem label="slideDuration:">
                <s:NumericStepper id="numericStepper"
                        minimum="0"
                        maximum="10000"
                        value="200"
                        valueInterval="100"
                        change="numericStepper_change(event);" />
            </mx:FormItem>
        </mx:Form>
    </mx:ApplicationControlBar>

    <s:HSlider id="slider"
            liveDragging="true"
            horizontalCenter="0"
            verticalCenter="0"
            left="20"
            right="20" />

</s:Application>

This entry is based on a beta version of the Flex 4 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 4 SDK.

  1. Thanks for laying out the Flex code like that. I found what I was missing. I was using a semicolon instead of a colon. I owe you one.
