[vtkusers] Jar File doesn't show render window

[Marc Meidinger]

***Update***

I missed to copy the lower part of main function into to the error
description. It's corrected in the following code. But the problem still
isn't solved.

 Good Morning vtk users!

I'm a VTK beginner. I just have installed vtk and wrote my first application
in Java on Eclipse (on WinXP). I display the render window in a JPanel which
is added to a JFrame. When compiling everything works fine till I try to
create & run the JAR File ->
After I doubleclick the JAR File, nothing happens. (But when I remove the
Panel with the vtk render window the empty Frame appears, correctly.) 

What am I doing wrong, why doesnt my JAR File show me the render window? I
would be glad about some quick help.

Thanks.

Sincerely, Marc Meidinger

 

Here is the main method which creates the JFrame and the JPanel class which
displays the vtk Modell (from Spectrogramm) 

// the main function
public static void main (String[] args)
{ 
 SpecPanel oPanel = new SpecPanel();
    
 JFrame frame = new JFrame("3D Spectrogramm");
 frame.getContentPane().setLayout(new GridLayout(1,1));
 frame.addWindowListener(new WindowAdapter() 
   {
     public void windowClosing(WindowEvent e) {System.exit(0);}
   }); 
 frame.getContentPane().add("Center", oPanel);
 frame.pack();
 frame.setBounds(100, 100, 1000, 1000);
 frame.setVisible(true);
}

 

package HelloVtkMain;
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.*;
import vtk.*;

public class SpecPanel extends JPanel {


  Spectrogramm spec = new Spectrogramm( 100, 100, 100 ); // creates a VTK
modell
   
   public SpecPanel()
   {  
  
    //Set Panel Layout
    setLayout(new BorderLayout());
    
    //Get the Canvas
    vtkCanvas oCanvas = spec.getSpectrogrammCanvas();

    //Set Camera on Canvas
    oCanvas.GetRenderer().ResetCamera();
    
    //Size the Canvas
    oCanvas.setSize(1000, 1000);
    
    //Add Canvas to Panel
    this.add(oCanvas, BorderLayout.CENTER);
   }
}
