Serializable
public abstract class GraphicsConfigTemplate extends Object implements Serializable
TheGraphicsConfigTemplate
class is used to obtain a validGraphicsConfiguration
. A user instantiates one of these objects and then sets all non-default attributes as desired. TheGraphicsDevice.getBestConfiguration(java.awt.GraphicsConfigTemplate)
method found in theGraphicsDevice
class is then called with thisGraphicsConfigTemplate
. A validGraphicsConfiguration
is returned that meets or exceeds what was requested in theGraphicsConfigTemplate
.- Since:

Field Detail
REQUIRED
public static final int REQUIRED
Value used for "Enum" (Integer) type. States that this feature is required for theGraphicsConfiguration
object. If this feature is not available, do not select theGraphicsConfiguration
object.- See Also:
- Constant Field Values
PREFERRED
public static final int PREFERRED
Value used for "Enum" (Integer) type. States that this feature is desired for theGraphicsConfiguration
object. A selection with this feature is preferred over a selection that does not include this feature, although both selections can be considered valid matches.- See Also:
- Constant Field Values
UNNECESSARY
public static final int UNNECESSARY
Value used for "Enum" (Integer) type. States that this feature is not necessary for the selection of theGraphicsConfiguration
object. A selection without this feature is preferred over a selection that includes this feature since it is not used.- See Also:
- Constant Field Values

Method Detail
getBestConfiguration
public abstract GraphicsConfiguration getBestConfiguration(GraphicsConfiguration[] gc)
Returns the "best" configuration possible that passes the criteria defined in theGraphicsConfigTemplate
.- Parameters:
gc
- the array ofGraphicsConfiguration
objects to choose from.- Returns:
-
a
GraphicsConfiguration
object that is the best configuration possible. - See Also:
GraphicsConfiguration
isGraphicsConfigSupported
public abstract boolean isGraphicsConfigSupported(GraphicsConfiguration gc)
Returns aboolean
indicating whether or not the specifiedGraphicsConfiguration
can be used to create a drawing surface that supports the indicated features.- Parameters:
gc
- theGraphicsConfiguration
object to test- Returns:
true
if thisGraphicsConfiguration
object can be used to create surfaces that support the indicated features;false
if theGraphicsConfiguration
can not be used to create a drawing surface usable by this Java(tm) API.
