GraphicsConfigTemplate

Class Overview

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 getBestConfiguration(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.

GraphicsConfigTemplate()
This class is an abstract class so only subclasses can be instantiated.
Public Methods
abstract GraphicsConfiguration getBestConfiguration(GraphicsConfiguration[] gc)
Returns the "best" configuration possible that passes the criteria defined in the GraphicsConfigTemplate.
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.

Constants

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 Value: 2 (0x00000002)

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 Value: 1 (0x00000001)

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.

Constant Value: 3 (0x00000003)

Public Constructors

public GraphicsConfigTemplate ()

This class is an abstract class so only subclasses can be instantiated.

Public Methods

public abstract GraphicsConfiguration getBestConfiguration (GraphicsConfiguration[] gc)

Returns the "best" configuration possible that passes the criteria defined in the GraphicsConfigTemplate.

Parameters
gc the array of GraphicsConfiguration objects to choose from.
Returns
  • a GraphicsConfiguration object that is the best configuration possible.

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.
