Problem with JTable

Felissa · #1 (**permalink**) 07-04-2007, 10:21 AM

Hi, it's just a simple question, i like to have a jtable displays just a few columns...

here's the code:

Code:

package ch.svenu.jTableXP;
import java.awt.Dimension;
import java.util.ArrayList;

import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

import infrastructure.interfaces.*;
 
public class jT extends DefaultTableModel{

	public jT(){
		//Faked results
		ArrayList<Record> myResults = new ArrayList<Record>();
		myResults.add(new TempResult("One", "U2", "2007-04-01 08:15:02", "3:42"));
		myResults.add(new TempResult("Two had found three fours of five", "The Black Eyed Peas", "2007-04-01 08:19:31", "4:07"));
		myResults.add(new TempResult("Number three", "Jonny Cash", "2007-04-01 08:25:10", "2:58"));
        
        //Tableheaders
        String[] myHeaders = {"Title",
                "Artist",
                "Start",
                "Duration"};
        
        final JTable table = new JTable(myResults, myHeaders);
        table.setPreferredScrollableViewportSize(new Dimension(500, 70));
        
	}

	/**
     * Temporary class that implements Record.
     * For testing only.
     * 
     * @author sCHween
     */
    class TempResult implements Record
    {
        private String artist;
        private String duration;
        private String start;
        private String title;
        
        public TempResult(String t, String a, String s, String d)
        {
            artist = a;
            title = t;
            start = s;
            duration = d;
        }

        public String getArtist()
        {
            return artist;
        }

        public String getEffDuration()
        {
            return duration;
        }

        public String getStartTime()
        {
            return start;
        }

        public String getTitle()
        {
            return title;
        }
        
    }

}

Now this line is my problem:

Code:

final JTable table = new JTable(myResults, myHeaders);

Thanks

Here is a nice tutorial on the use of JTables:

This will tell you had to add items, create cells and add them, and how else to mess with the container of a jTable.

hi, think i made a step forward, but i'm still stuck within.

Code:

package gui;

import java.util.ArrayList;

import infrastructure.interfaces.Record;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.TableModel;

public class test{
	ArrayList<Record> results;
	public test() {
		// // // // // // // // // // // // // // // // // // // // // //
		// TEMPORARY RESULTS IMPLEMENTATION //
		// // // // // // // // // // // // // // // // // // // // // //
		ArrayList<Record> results = new ArrayList<Record>();
		results.add(new TempResult("One", "U2", "2007-04-01 08:15:02", "3:42"));
		results.add(new TempResult("Two had found three fours of five",
				"The Black Eyed Peas", "2007-04-01 08:19:31", "4:07"));
		results.add(new TempResult("Number three", "Jonny Cash",
				"2007-04-01 08:25:10", "2:58"));
		
		// Das JTable initialisieren
		final TableModel rtm = new ReporterTableModel();
		final JTable table = new JTable(rtm);

		final JFrame frame = new JFrame("Reporter ");
		frame.getContentPane().add(new JScrollPane(table));
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.pack();
		frame.setVisible(true);
	}

	public static void main(String[] args) {
		new test();
	}
   

   // // // // // // // // // // // // // // // // // // // // // //
   // TEMPORARY CLASS IMPLEMENTATIONS							  //
   // // // // // // // // // // // // // // // // // // // // // //
    
   /**
    * Temporary class that implements Record.
    * For testing only.
    * 
    * @author brudt1
    */
   class TempResult implements Record
   {
       private String artist;
       private String duration;
       private String start;
       private String title;
       
       public TempResult(String t, String a, String s, String d)
       {
           artist = a;
           title = t;
           start = s;
           duration = d;
       }

       public String getArtist()
       {
           return artist;
       }

       public String getEffDuration()
       {
           return duration;
       }

       public String getStartTime()
       {
           return start;
       }

       public String getTitle()
       {
           return title;
       }
       
   }

The ReporterTabelModel.java looks like this:

Code:

package gui;

import javax.swing.table.AbstractTableModel;
import infrastructure.interfaces.Record;

public class ReporterTableModel extends AbstractTableModel{


	public int getColumnCount() {
	        return 4;
	}

	public int getRowCount() {
		return 0;
	}

	public Object getValueAt(int rowIndex, int columnIndex) {
		Record result = results.get( rowIndex );
		return null;
	}

	@Override
	public String getColumnName(int column) {
		switch( column ){
        case 0: return "Artist";
        case 1: return "Title";
        case 2: return "Starttime";
        case 3: return "Duration";
        default: return null;
     } 
	}

}

Now the problem i got - the getValueAt.
There i need access to my ArrayList results and with the columnIndex i have to read the value.
But i couldn't access my results served from test.java.
Thanks
