[gl4java-usergroup] Flicker problem

[Otto L. <ott...@ya...>]

Whenever the "GLCanvas" looses focus to the
Button widget the canvas flicker. 
Does anyone know how to get around this problem?
The code follows below.
My platform is Linux (NVidia).

import gl4java.utils.glut.*;

public class testgl {
    
    GLCanvas glc;
    void test() {
	JFrame f= new JFrame();
	glc= new GLCanvas(200,200);

	f.setSize(800,600);


	f.getContentPane().setLayout(new
BorderLayout());

	f.getContentPane().add(new JButton("Foo"),
BorderLayout.EAST);
	f.getContentPane().add(glc, BorderLayout.CENTER);


	f.addWindowListener(new WindowAdapter() {
		public void windowClosing(WindowEvent e) {
		    glc.cvsDispose();
		    System.exit(0);
		}
	    });

	f.show();
    }

    public static void main(String arg[]) {
	(new testgl()).test();
    }


}
