1012: Mainline

In a subclass of the MovieTableApplication class, you connect your new listener to the rating-table model. All the subclass definition does is to call addListSelectionListener on the appropriate target with an instance of the MovieTableCellListener class defined in Segment 1011 as an ordinary argument.

Note that you must not have row selection turned on, as row selection would interfere with cell editing. Accordingly, you should use the RatingTable definition provided in Segment 1000.

import javax.swing.table.*; 
public class CellMovieTableApplication extends MovieTableApplication { 
 public CellMovieTableApplication () {  
  TableModel tm = getRatingTable().getModel(); 
  tm.addTableModelListener(new MovieTableCellListener(this)); 
 }                                                                       
 public static void main (String argv []) { 
  JFrame frame = new JFrame("Movie Data Table"); 
  frame.getContentPane().add("Center",  
                             new CellMovieTableApplication()); 
  frame.setSize(750, 210); 
  frame.addWindowListener(new ApplicationClosingWindowListener()); 
  frame.show(); 
 }
