Toggling data tips on a Spark HSlider control in Flex 4

By Peter deHaan On March 5, 2009 · Leave a Comment

The following example shows how you can disable scroll data tips on a Spark HSlider control in Flex 4 by setting the Boolean showDataTip property.

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

<s:Application name="Spark_HSlider_showDataTip_test"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:controlBarContent>
        <mx:Form styleName="plain">
            <mx:FormItem label="showDataTip:">
                <s:CheckBox id="checkBox" selected="true" />
            </mx:FormItem>
        </mx:Form>
    </s:controlBarContent>
 
    <s:HSlider showDataTip="{checkBox.selected}"
            horizontalCenter="0" verticalCenter="0" />
 
</s:Application>

You can also set the showDataTip property using ActionScript, as seen in the following example:

<s:Application name="Spark_HSlider_showDataTip_test"
        xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:controlBarContent>
        <mx:Form styleName="plain">
            <mx:FormItem label="showDataTip:">
                <s:CheckBox id="checkBox"
                        selected="true"
                        change="sldr.showDataTip = checkBox.selected;"/>
            </mx:FormItem>
        </mx:Form>
    </s:controlBarContent>
 
    <s:HSlider id="sldr"
            horizontalCenter="0" verticalCenter="0" />
 
</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.
