Skinning TLF-based text controls
You do not typically add skins or chrome to the Spark text
The Label, RichText, and RichEditableText Spark text controls
are used in the skins of skinnable components. Because each has
a different set of features, you can use the lightest weight text
control that meets your needs.
For example, the default skin of a Spark Button uses the Label
class to render the label of the Button. If you have a Button that
requires rich text, you can sometimes replace the Label control
in its skin with a RichText control.
The default skins of the Spark TextInput and TextArea controls
use a RichEditableText control to provide an area in which text
can be edited. The border and background are provided by a Rect
class, and the scrollbars by a Scroller class.
