Class java.awt.GraphicsConfigTemplate

java.lang.Object
  |
  +--java.awt.GraphicsConfigTemplate

public abstract class GraphicsConfigTemplate

extends Object

implements Serializable

This class is used to obtain a valid GraphicsConfiguration. A user instantiates one of these objects and then sets all non-default attributes as desired. The getGraphicsConfiguration method found in the GraphicsDevice class is then called with this GraphicsConfigTemplate. A valid GraphicsConfiguration is returned that meets or exceeds what was requested in the GraphicsConfigTemplate.

Since:

JDK1.2
