Examples of com.sun.dtv.lwuit.Graphics

com.sun.dtv.lwuit.Graphics
Abstracts the underlying platform graphics context thus allowing us to achieve portability between MIDP devices and CDC devices. This abstaction simplifies and unifies the Graphics implementations of various platforms.
A graphics instance is never created by the developer and is always accessed using either a paint callback or a mutable image. There is no way to create this object directly.
