public class NewtCanvasAWT
AWT Canvas containing a NEWT Window using native parenting.

maybe called to use an offscreen drawable (FBO or PBuffer) allowing
the underlying JAWT mechanism to composite the image, if supported.

public void setShallUseOffscreenLayer(boolean v)
OffscreenLayerOption
Shall be called before the first NativeSurface.lockSurface(),
and hence before realization.
setShallUseOffscreenLayer in interface OffscreenLayerOptionOffscreenLayerOption.getShallUseOffscreenLayer(),
OffscreenLayerOption.isOffscreenLayerSurfaceEnabled()public final boolean getShallUseOffscreenLayer()
OffscreenLayerOptionOffscreenLayerOption.setShallUseOffscreenLayer(boolean).
getShallUseOffscreenLayer in interface OffscreenLayerOptionpublic final boolean isOffscreenLayerSurfaceEnabled()
OffscreenLayerOption
This instance is an offscreen layer, if setShallUseOffscreenLayer(true)
has been called before it's realization and first lock and the underlying implementation supports it.
NativeSurface.lockSurface().
isOffscreenLayerSurfaceEnabled in interface OffscreenLayerOptionOffscreenLayerOption.setShallUseOffscreenLayer(boolean)public boolean isApplet()
Applet,
otherwise false. This information is valid only after addNotify() is issued,
ie. before adding the component to the AWT tree and make it visible.
public Window setNEWTChild(Window newChild)
A previously detached newChild will be released to top-level status
and made invisible.
Note: When switching NEWT child's, detaching the previous first via setNEWTChild(null)
produced much cleaner visual results.
