Styles that are not found in Flex documentation

today I wanted to change the border color of TextInput when user has a focus on it. I could not find any style that would allow me to change that. A little bit of Google searching and I found answer to be themeColor.

Why is it that there are some styles that work and which are not even mentioned in the Flex documentation? (and how can on开发者_如何学Pythone find out about em, except doing some web searching?)

Thanx Ladislav

As always I suggest while managing in color and properties use Flex Style Explorer create a stylesheet.css, put it into src folder and then call it by the following statement:

<mx:Style source="yourstylesheet.css" />

In the comment above Srirangan answered the question correctly, but I am not able to accept his comment as answer to my question...so I will just accept this one :)
