Flex Examples
In a previous example, “Styling Alert controls in Flex using the StyleManager class and setStyle() methods”, we saw how to style a Flex Alert control using the static StyleManager.getStyleDeclaration() method, and the setStyle() method.
The following example shows how you can do the same thing using the beta Flex 4 SDK by passing a fully qualified class name to the static getStyleDeclaration() method.
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.

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.

Thank you Peter, but do you know why with Gumbo ( I use FB 4 beta ) not all properties of Alert work. For example
alertCSS.setStyle(“cornerRadius”, 5);
doesn’t work.
gregloby,
In Flex 4, not all the styles are supported by the default spark skins. The easiest solution is to create a custom skin.
In fact, I’ll create a new post since the code is a bit long to put here… Stay tuned.

For an example, see Setting the corner radius on the Halo Alert control in Flex 4.
Thank you Peter,
you’re great :)
Without styleManager, and not persistant :
var a:Alert = Alert.show(‘blabla’);
a.setStyle(‘chromeColor’, ‘red’);
