mixing java2d and jogl2 troubles

[dim_9999]

Hello everybody!

I try to explain my problem…
I am trying to use GLJpanel as canvas instead GLCanvas. So, on my top frame, i put my JPanel and enclosing canvas; JPanel contains some gradient as background and a text at front. So, if i want to see my JPanel, i need to set up canvas.setOpaque(false) for transparent view, and in init() metod set gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f), i guess… well, at finally i got an exception…

here is the code:

			}
		};
		renderPane.setLayout(new BorderLayout());
		renderPane.setOpaque(false);
		renderPane.setPreferredSize(new Dimension(400, 300));
//		GLCanvas canvas = new GLCanvas(); // the canvas

		caps.setAlphaBits(8);
		GLJPanel canvas = new GLJPanel(caps);
		canvas.setOpaque(false);
		
		// the animator uses fixed rate scheduling
		renderPane.add(canvas, BorderLayout.CENTER);
		return renderPane;
	}

Hi!

I’m not sure, I think it is a known bug of JOGL. GLJPanel is a bit broken, avoid using it if possible. I have no access to Microsoft Windows and your bug is specific to this platform. Please ask some help here: http://jogamp.762907.n3.nabble.com/jogl-f782158.html
