public final AbstractGraphicsConfiguration chooseGraphicsConfiguration(CapabilitiesImmutable capsChosen, CapabilitiesImmutable capsRequested, CapabilitiesChooser chooser, AbstractGraphicsScreen screen) throws IllegalArgumentException, NativeWindowException
Selects a graphics configuration on the specified graphics
device compatible with the supplied Capabilities
. Some
platforms (e.g.: X11, EGL, KD) require the graphics configuration
to be specified when the native window is created.
These architectures have seperated their device, screen, window and drawable
context and hence are capable of quering the capabilities for each screen.
A fully established window is not required.
Other platforms (e.g. Windows, MacOSX) don't offer the mentioned seperation
and hence need a fully established window and it's drawable.
Here the validation of the capabilities is performed later.
In this case, the AbstractGraphicsConfiguration implementation
must allow an overwrite of the Capabilites, for example
DefaultGraphicsConfiguration.setChosenCapabilities(..)
.
This method is mainly intended to be both used and implemented by the OpenGL binding.
The concrete data type of the passed graphics device and
returned graphics configuration must be specified in the
documentation binding this particular API to the underlying
window toolkit. The Reference Implementation accepts AWTGraphicsDevice
objects and returns AWTGraphicsConfiguration
objects. On
X11 platforms where the AWT is not in use, it also accepts
X11GraphicsDevice
objects and returns X11GraphicsConfiguration
objects.
