X11GraphicsDevice
public X11GraphicsDevice(String connection, int unitID)
Constructs a new X11GraphicsDevice corresponding to the given connection and defaultToolkitLockviaNativeWindowFactory.getDefaultToolkitLock(String).
Note that this is not an open connection, ie no native display handle exist. This constructor exist to setup a default device connection.

X11GraphicsDevice
public X11GraphicsDevice(long display, int unitID, ToolkitLock locker, boolean owner)- Parameters:
display- the Display connectionlocker- customToolkitLock, eg to force null locking w/ private connection- See Also:
DefaultGraphicsDevice(String, String, int, long, ToolkitLock)

X11GraphicsDevice
public X11GraphicsDevice(String displayConnection, int unitID, ToolkitLock locker)
Constructs a new X11GraphicsDevice corresponding to the given display connection.The constructor opens the native connection and takes ownership.
- Parameters:
displayConnection- the semantic display connection namelocker- customToolkitLock, eg to force null locking w/ private connection- See Also:
DefaultGraphicsDevice(String, String, int, long, ToolkitLock)

Method Detail
-
getDefaultScreen
public int getDefaultScreen()
Returns the default screen number as referenced by the display connection, i.e. 'somewhere:0.1' -> 1Implementation uses the XLib macro
DefaultScreen(display).
-
getDefaultVisualID
public int getDefaultVisualID()
-
isXineramaEnabled
public final boolean isXineramaEnabled()
-
clone
public Object clone()
- Specified by:
clonein interfaceAbstractGraphicsDevice- Overrides:
clonein classDefaultGraphicsDevice
-
open
public boolean open()
Description copied from interface:AbstractGraphicsDeviceOptionally [re]opening the device if handle isnull.The default implementation is a
NOP.Example implementations like
X11GraphicsDeviceorEGLGraphicsDeviceissue the native open operation in case handle isnull.- Specified by:
openin interfaceAbstractGraphicsDevice- Overrides:
openin classDefaultGraphicsDevice- Returns:
- true if the handle was
nulland opening was successful, otherwise false.
-
close
public boolean close()
Description copied from interface:AbstractGraphicsDeviceOptionally closing the device if handle is notnull.The default implementation
disposeit'sToolkitLockand sets the handle tonull.Example implementations like
X11GraphicsDeviceorEGLGraphicsDeviceissue the native close operation or skip it depending on thehandles's ownership.- Specified by:
closein interfaceAbstractGraphicsDevice- Overrides:
closein classDefaultGraphicsDevice- Returns:
- true if the handle was not
nulland closing was successful, otherwise false.
