Flex Examples

The following example shows how you can change the Button control’s borderColor and themeColor properties to one of the special Flex “halo” colors (”haloBlue”, “haloGreen”, “haloOrange” or “haloSilver”). Note that you can also use any other named or hex color as well, such as “red” or 0xFF0000.
