[vtkusers] VTK java wrapper and Swing

[Jonathan Ruiz Peinado]

Hi, I'm sure this is an easy question but I'm a bit Stuck on it.


When I use the example class SimpleVTK in other class I get an ugly FATAL
error, I think that i's something about Swing and  vtkPanel...

Any ideas? ,  thanks in advance

public class OtherClass  {

    public static void main(String s[]) {
               JFrame frame = new JFrame("SimpleVTK");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.getContentPane().setLayout(new BorderLayout());
                frame.getContentPane().add(new SimpleVTK(),
BorderLayout.CENTER);
                frame.setSize(400, 400);
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
    }
}
