public abstract class GraphicsConfigTemplate extends Object implements Serializable
GraphicsConfigTemplate
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
GraphicsDevice.getBestConfiguration(java.awt.GraphicsConfigTemplate)
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
.GraphicsDevice
