public interface BackgroundPainterStrategy
RTextAreaBase. The Strategy pattern is used for this
object because the background can be painted as a solid color, as
an image, and possibly other ways (gradients, animated images, etc.).
When a method to change the background of an RTextAreaBase
instance is called (such as setBackground,
setBackgroundImage or setBackgoundObject),
the correct strategy is then created and used to paint its background.ImageBackgroundPainterStrategy,
