Interface GraphicsContext

All Known Implementing Classes:

GCGraphicsContext, GraphicsWrapper

public interface GraphicsContext

An interface for the graphics implementation responsible for rendering onto a particular UI component. This interface is intended to be independent of the underlying UI, but will reference some AWT classes, such as java.awt.Shape and java.awt.Color as they are not associated with any UI components and are already available.
