Introducing the StyleManager.selectors property in Flex 3

I was testing this today, and thought some people might find it useful. In more recent builds of the Flex 3 SDK, the StyleManager now includes a new static, read-only property, selectors. To quote the bug notes:

…This property returns an array of strings representing all of the selectors registered with the StyleManager.

For more information check out the bug at “[SDK-11706] Expose All Existing Styles via StyleManager”, and download a recent nightly build of the Flex 3 SDK at “Adobe Labs – Flex 3 Software Developement Kit”.

And as always, you can read the source code for the StyleManager class by extracting the SDK ZIP file and going to: “[flex_sdk_3.zip]\frameworks\projects\framework\src\mx\styles\StyleManager.as”.

The following example shows how you can use the new static selectors property in the Flex 3 StyleManager class to display a list of selectors currently registered with the style manager.
