Constructor and Description
X11GraphicsDevice(long display, int unitID, boolean owner) Constructs a new X11GraphicsDevice corresponding to the given native display handle and default ToolkitLock via NativeWindowFactory.createDefaultToolkitLock(String, long).
X11GraphicsDevice(long display, int unitID, ToolkitLock locker, boolean owner)
X11GraphicsDevice(String connection, int unitID) Constructs a new X11GraphicsDevice corresponding to the given connection and default ToolkitLock via NativeWindowFactory.getDefaultToolkitLock(String). Note that this is not an open connection, ie no native display handle exist.

Constructor Detail

X11GraphicsDevice

public X11GraphicsDevice(String connection,
                 int unitID)

Constructs a new X11GraphicsDevice corresponding to the given connection and default ToolkitLock via NativeWindowFactory.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,
                 boolean owner)

Constructs a new X11GraphicsDevice corresponding to the given native display handle and default ToolkitLock via NativeWindowFactory.createDefaultToolkitLock(String, long).

DefaultGraphicsDevice.DefaultGraphicsDevice(String, String, int, long)

X11GraphicsDevice

public X11GraphicsDevice(long display,
                 int unitID,
                 ToolkitLock locker,
                 boolean owner)

Parameters:

display - the Display connection

locker - custom ToolkitLock, eg to force null locking in NEWT

Method Detail

getDefaultVisualID

public int getDefaultVisualID()

clone

public Object clone()

Overrides:

clone in class DefaultGraphicsDevice

open

public boolean open()

Description copied from interface: AbstractGraphicsDevice

Optionally [re]opening the device if handle is null.

The default implementation is a NOP.

Example implementations like X11GraphicsDevice or EGLGraphicsDevice issue the native open operation in case handle is null.

Specified by:

open in interface AbstractGraphicsDevice

Overrides:

open in class DefaultGraphicsDevice

Returns:

true if the handle was null and opening was successful, otherwise false.

close

public boolean close()

Description copied from interface: AbstractGraphicsDevice

Optionally closing the device if handle is not null.

The default implementation is a NOP, just setting the handle to null.

Example implementations like X11GraphicsDevice or EGLGraphicsDevice issue the native close operation or skip it depending on the handles's ownership.

Specified by:

close in interface AbstractGraphicsDevice

Overrides:

close in class DefaultGraphicsDevice

Returns:

true if the handle was not null and closing was successful, otherwise false.
