public class DefaultGLCapabilitiesChooser extends java.lang.Object implements GLCapabilitiesChooser
The default implementation of the GLCapabilitiesChooser
interface, which provides consistent visual
selection behavior across platforms. The precise algorithm is
deliberately left loosely specified. Some properties are:

chooseCapabilities(GLCapabilities desired,
GLCapabilities[] available,
int windowSystemRecommendedChoice)
Chooses the index (0..available.length - 1) of the
GLCapabilities most closely matching the desired one from the
list of all supported. |
public int chooseCapabilities(GLCapabilities desired, GLCapabilities[] available, int windowSystemRecommendedChoice)
GLCapabilitiesChooser
GLCapabilities
most closely matching the desired one from the
list of all supported. Some of the entries in the
available
array may be null; the chooser must
ignore these. The windowSystemRecommendedChoice
parameter may be provided to the chooser by the underlying
window system; if this index is valid, it is recommended, but
not necessarily required, that the chooser select that entry.
Note: this method is called automatically by the
GLDrawableFactory
when an instance of this class is
passed in to one of its factory methods. It should generally not
be invoked by users directly, unless it is desired to delegate
the choice to some other GLCapabilitiesChooser object.
