Flex 4: StyleManager.getStyleManager()

I'm trying to compile existing Flex 4 project but having an error:

Call to underfined met开发者_如何学JAVAhod getStyleManager of StyleManager class.

The code is:

var styleManager:IStyleManager2 = StyleManager.getStyleManager(null);

I found the method in Flex documentation but when I open StyleManager.as I can't find the method declaration.

Used Flex SDK 4.0.0.10485 from here.

Try upgrading your version of Flex, is that possible? It's working for me, I do this:

import mx.managers.SystemManagerGlobals;

public static function getStyleManager():IStyleManager2
{
    return mx.styles.StyleManager.getStyleManager(SystemManagerGlobals.topLevelSystemManagers[0]);
}

I'm using Flex 13645.

It also depends on when you're calling StyleManager possibly: if you're calling that method in a Preloader, that could be a problem.

Each app has its own StyleManager in Flex 4. You access it with the styleManager property (note the lowercase "s"), whereas before you used the static class StyleManager to get an instance.

Here's a page that describes how to use the StyleManager class: http://help.adobe.com/en_US/Flex/4.0/UsingSDK/WS2db454920e96a9e51e63e3d11c0bf69084-7f7c.html

Please check this following link,

The correct way now of using the StyleManager would be the following,

var tempStyle:CSSStyleDeclaration = StyleManager.getStyleManager(null).getStyleDeclaration(”.tempStyle”);

StyleManager.getStyleManager(null);, returns the top level instance of StyleManager.
