Styles
 Style Description Defined By
  
disabledSkin
Type: Class
The class that provides the background for the TextArea component when its enabled property is set to false. The default value is TextArea_disabledSkin.

embedFonts
Type: Boolean
Indicates whether embedded font outlines are used to render the text field. If this value is true, Flash Player renders the text field by using embedded font outlines. If this value is false, Flash Player renders the text field by using device fonts.

If you set the embedFonts property to true for a text field, you must specify a font for that text by using the font property of a TextFormat object that is applied to the text field. If the specified font is not embedded in the SWF file, the text is not displayed.

The default value is false.
