Constructor Detail

DefaultGraphicsConfiguration

public DefaultGraphicsConfiguration(AbstractGraphicsScreen screen,
                                    CapabilitiesImmutable capsChosen,
                                    CapabilitiesImmutable capsRequested)

Method Detail

clone

public Object clone()

Specified by:

clone in interface AbstractGraphicsConfiguration

getScreen

public final AbstractGraphicsScreen getScreen()

Description copied from interface: AbstractGraphicsConfiguration

Return the screen this graphics configuration is valid for

Specified by:

getScreen in interface AbstractGraphicsConfiguration

getChosenCapabilities

public final CapabilitiesImmutable getChosenCapabilities()

Description copied from interface: AbstractGraphicsConfiguration

Return the capabilities reflecting this graphics configuration, which may differ from the capabilities used to choose this configuration.

Specified by:

getChosenCapabilities in interface AbstractGraphicsConfiguration

Returns:

An immutable instance of the Capabilities to avoid mutation by the user.

getRequestedCapabilities

public final CapabilitiesImmutable getRequestedCapabilities()

Description copied from interface: AbstractGraphicsConfiguration

Return the capabilities used to choose this graphics configuration. These may be used to reconfigure the NativeWindow in case the device changes in a multiple screen environment.

Specified by:

getRequestedCapabilities in interface AbstractGraphicsConfiguration

Returns:

An immutable instance of the Capabilities to avoid mutation by the user.

getNativeGraphicsConfiguration

public AbstractGraphicsConfiguration getNativeGraphicsConfiguration()

Description copied from interface: AbstractGraphicsConfiguration

In case the implementation utilizes a delegation pattern to wrap abstract toolkits, this method shall return the native AbstractGraphicsConfiguration, otherwise this instance.

Specified by:

getNativeGraphicsConfiguration in interface AbstractGraphicsConfiguration

NativeSurface.getGraphicsConfiguration()

getVisualID

public final int getVisualID(VisualIDHolder.VIDType type)
                      throws NativeWindowException

Description copied from interface: VisualIDHolder

Returns the native visual ID of the given type if supported, or VisualIDHolder.VID_UNDEFINED if not supported.

Depending on the native windowing system, type is handled as follows:

• X11 throws NativeWindowException on EGL_CONFIG, WIN32_PFD
  • INTRINSIC: X11 XVisual ID
  • NATIVE: X11 XVisual ID
  • X11_XVISUAL: X11 XVisual ID
  • X11_FBCONFIG: VID_UNDEFINED
• X11/GL throws NativeWindowException on EGL_CONFIG, WIN32_PFD
  • INTRINSIC: X11 XVisual ID
  • NATIVE: X11 XVisual ID
  • X11_XVISUAL: X11 XVisual ID
  • X11_FBCONFIG: X11 FBConfig ID or VID_UNDEFINED
• Windows/GL throws NativeWindowException on EGL_CONFIG, X11_XVISUAL, X11_FBCONFIG
  • INTRINSIC: Win32 PIXELFORMATDESCRIPTOR ID
  • NATIVE: Win32 PIXELFORMATDESCRIPTOR ID
  • WIN32_PFD: Win32 PIXELFORMATDESCRIPTOR ID
• EGL/GL throws NativeWindowException on X11_XVISUAL, X11_FBCONFIG, WIN32_PFD
  • INTRINSIC: EGL Config ID
  • NATIVE: EGL NativeVisual ID (X11 XVisual ID, Win32 PIXELFORMATDESCRIPTOR ID, ...)
  • EGL_CONFIG: EGL Config ID

Note: INTRINSIC and NATIVE are always handled, but may result in VisualIDHolder.VID_UNDEFINED. The latter is true if the native value are actually undefined or the corresponding object is not mapped to a native visual object.

Specified by:

getVisualID in interface VisualIDHolder

Throws:

NativeWindowException - if type is neither INTRINSIC nor NATIVE and does not match the native implementation.
