Method Detail

chooseCapabilities

public int chooseCapabilities(CapabilitiesImmutable desired,
                              List available,
                              int windowSystemRecommendedChoice)
Description copied from interface: javax.media.nativewindow.CapabilitiesChooser
Chooses the index (0..available.length - 1) of the Capabilities 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 GraphicsConfigurationFactory.chooseGraphicsConfiguration(javax.media.nativewindow.CapabilitiesImmutable, javax.media.nativewindow.CapabilitiesImmutable, javax.media.nativewindow.CapabilitiesChooser, javax.media.nativewindow.AbstractGraphicsScreen) method when an instance of this class is passed in to it. It should generally not be invoked by users directly, unless it is desired to delegate the choice to some other CapabilitiesChooser object.
