- java.lang.Object
-
- java.awt.GraphicsConfigTemplate

- All Implemented Interfaces:
- Serializable
public abstract class GraphicsConfigTemplate extends Object implements Serializable
TheGraphicsConfigTemplateclass 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 theGraphicsDeviceclass is then called with thisGraphicsConfigTemplate. A validGraphicsConfigurationis 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 theGraphicsConfigurationobject. If this feature is not available, do not select theGraphicsConfigurationobject.- See Also:
- Constant Field Values
PREFERRED
public static final int PREFERRED
Value used for "Enum" (Integer) type. States that this feature is desired for theGraphicsConfigurationobject. 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 theGraphicsConfigurationobject. 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 ofGraphicsConfigurationobjects to choose from. - Returns:
-
a
GraphicsConfigurationobject that is the best configuration possible. - See Also:

GraphicsConfiguration
isGraphicsConfigSupported
public abstract boolean isGraphicsConfigSupported(GraphicsConfiguration gc)
Returns abooleanindicating whether or not the specifiedGraphicsConfigurationcan be used to create a drawing surface that supports the indicated features.- Parameters:
-
gc- theGraphicsConfigurationobject to test - Returns:
-
trueif thisGraphicsConfigurationobject can be used to create surfaces that support the indicated features;falseif theGraphicsConfigurationcan not be used to create a drawing surface usable by this Java(tm) API.
