[vtkusers] VTK java wrapper and Swing

[Sebastien Jourdain]

Hi Jonathan,

could you try using the EDT to create your swing components like follow:

 public static void main(String s[]) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                 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);
            }
        });
}

If that's not working could you send your file:
/home/jruiz/NetBeansProjects/Dicom Studio/hs_err_pid12761.log (or the
new one...)

Thanks,

Seb
