The following example shows how you can set the corner radius on a Spark Border container in Flex 4 by setting the cornerRadius 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.
The following example requires Flex SDK 4.0.0.10008 or later.

You can also set the cornerRadius style in an external .CSS file or <Style/> block, as seen in the following example:
<?xml version="1.0" encoding="utf-8"?> <!-- http://blog.flexexamples.com/2009/09/04/setting-the-corner-radius-on-a-spark-border-container-in-flex-4/ --> <s:Application name="Spark_Border_cornerRadius_test" xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Style> @namespace s "library://ns.adobe.com/flex/spark"; s|Border { cornerRadius: 50; } </fx:Style> <s:Border id="brdr" width="80%" height="80%" horizontalCenter="0" verticalCenter="0"> <s:Label id="lbl" text="width:{brdr.width}, cornerRadius:{brdr.getStyle('cornerRadius')}" horizontalCenter="0" verticalCenter="0" /> </s:Border> </s:Application> |
Or you can set the cornerRadius style using ActionScript, as seen in the following example:
<?xml version="1.0" encoding="utf-8"?> <!-- http://blog.flexexamples.com/2009/09/04/setting-the-corner-radius-on-a-spark-border-container-in-flex-4/ --> <s:Application name="Spark_Border_cornerRadius_test" xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"> <s:controlBarContent> <s:Label text="cornerRadius:" /> <s:HSlider id="slider" minimum="0" maximum="100" value="2" change="slider_change(event);"/> </s:controlBarContent> <fx:Script> <![CDATA[ protected function slider_change(evt:Event):void { brdr.setStyle("cornerRadius", slider.value); } ]]> </fx:Script> <s:Border id="brdr" width="80%" height="80%" horizontalCenter="0" verticalCenter="0"> <s:Label id="lbl" text="width:{brdr.width}, cornerRadius:{brdr.getStyle('cornerRadius')}" horizontalCenter="0" verticalCenter="0" /> </s:Border> </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.
