A Canvas3D with implemented interface 'OffscreenLayerOption' and adapted context creation according to the design of AWT GLCanvas and as asked for by Sven above doesn't throw the GLException 'BackingLayerHost w/ unknown handle' anymore. Sweet Home 3D starts - unfortunately - with a not correctly positioned Canvas3D within a JSplitPane.

Emmanuel, thanks a lot for testing and providing pictures of this test case.

I transferred my changes into Harvey's Canvas3D and JoglPipeline classes and in agreement with him I make them available here. The file also includes the pictures : PastedGraphic-3.png/test result, PastedGraphic-4.png/default.

Changes in short:

Canvas3D/OffscreenLayerOption

  // Accessed in JoglPipeline.createNewContext    
  JAWTWindow jawtWindow = null;
  boolean shallUseOffscreenLayer = false;

  public void setShallUseOffscreenLayer(boolean v) {
    shallUseOffscreenLayer = v;
  }

  public final boolean getShallUseOffscreenLayer() {
    return shallUseOffscreenLayer;
  }

  public final boolean isOffscreenLayerSurfaceEnabled() {
    final JAWTWindow jawtwindow = jawtWindow;
    if (jawtwindow != null) {
      return jawtwindow.isOffscreenLayerSurfaceEnabled();
    }
    return false;
  }    

JoglPipeline.createNewContext

  cv.jawtWindow = (JAWTWindow)NativeWindowFactory.getNativeWindow(cv, awtGraphicsConfiguration);
  cv.jawtWindow.setShallUseOffscreenLayer(cv.shallUseOffscreenLayer);    
  cv.jawtWindow.lockSurface();
  try {
    draw = GLDrawableFactory.getFactory(profile).createGLDrawable(cv.jawtWindow)
    context = draw.createContext(context(shareCtx));
  }
  finally {
    cv.jawtWindow.unlockSurface();
  }

Emmanuel, is the Canvas3D positioned correctly when displayed in the separated window?

August
