Interface GLCapabilitiesChooser
- DefaultGLCapabilitiesChooser
public interface GLCapabilitiesChooser
Provides a mechanism by which applications can customize the
window type selection for a given
GLCapabilities
.
Developers can implement this interface and pass an instance into
the appropriate method of
GLDrawableFactory
; the chooser
will be called during the OpenGL context creation process.
chooseCapabilities
public int 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. 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.
