Class GraphicsConfigTemplate

java.lang.Object
  extended by java.awt.GraphicsConfigTemplate
All Implemented Interfaces:
Serializable

public abstract class GraphicsConfigTemplate
extends Object
implements Serializable

The 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.

1.2

Field Detail

REQUIRED

public static final int REQUIRED
Value used for "Enum" (Integer) type. States that this feature is required for the GraphicsConfiguration object. If this feature is not available, do not select the GraphicsConfiguration object.

Constant Field Values

PREFERRED

public static final int PREFERRED
Value used for "Enum" (Integer) type. States that this feature is desired for the GraphicsConfiguration 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.

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 the GraphicsConfiguration object. A selection without this feature is preferred over a selection that includes this feature since it is not used.

isGraphicsConfigSupported

public abstract boolean isGraphicsConfigSupported(GraphicsConfiguration gc)
Returns a boolean indicating whether or not the specified GraphicsConfiguration can be used to create a drawing surface that supports the indicated features.

Parameters:
gc - the GraphicsConfiguration object to test
Returns:
true if this GraphicsConfiguration object can be used to create surfaces that support the indicated features; false if the GraphicsConfiguration can not be used to create a drawing surface usable by this Java(tm) API.
