Animation for table cell renderer
Code shown below is a complete failure. Nothing is displayed on the target cell let alone do animation. What's wrong with this code?
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
import java.awt.event.*;
publicclass AnimeTableCell{
JFrame frame;
Container con;
JScrollPane scp;
JTable table;
AnimePanel anp, ant;
Image[] images;
public AnimeTableCell(){

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
con = frame.getContentPane();
images =new Image[4];
images[0] =new ImageIcon("images/a.png").getImage();
images[1] =new ImageIcon("images/b.png").getImage();
images[2] =new ImageIcon("images/c.png").getImage();
images[3] =new ImageIcon("images/d.png").getImage();

if (row == 3 && column == 2){
if (ant !=null){
c = ant;
}
}
return c;
}
};

con.add(scp, BorderLayout.CENTER);
ant =new AnimePanel(images, 500,true);//for cell renderer, repaint table
anp =new AnimePanel(images, 500,false);//this doesn't repaint table
con.add(anp, BorderLayout.SOUTH);
frame.setSize(400, 400);
frame.setVisible(true);
}
