issues with tables and swing

[Steph]

Hi. I'm having trouble getting the GUI to work. I have a class MatchesTable.java which passes all the JUnit tests we were given and which has the following code:

package au.edu.uq.csse2002.smartnotes;

import javax.swing.table.*;

public class MatchesTable extends AbstractTableModel {

	private Matches matches;

	public MatchesTable(Matches matches) {
		this.matches = matches;
	}

	public void setMatches(Matches matches) {
		this.matches = matches;
	}

	public Matches getMatches() {
		return matches;
	}

	public int getColumnCount() {
		return 2;
	}

	public int getRowCount() {
		return matches.size();
	}

	public Object getValueAt(int row, int col) {
		if (col == 0) {
			return (int)((matches.match(row).similarity())*100);
		}
		else {
			return matches.match(row).record().text();
		}
	}

	public String getColumnName(int col) {
		if (col == 0) {
			return "Relevance";
		}
		else {
			return "Record";
		}
	}
}

and then SmartNotes.java which contains the GUI functionality:

package au.edu.uq.csse2002.smartnotes;

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.*;

import javax.swing.*;
import javax.swing.border.Border;

public class SmartNotes extends JFrame{

	AbstractRecordReader recordReader;
	static JPanel jPanel = new JPanel(new FlowLayout());

	Matches matches;

	JTextField searchInput = new JTextField("");
	JButton searchButton = new JButton("Search");
	JTable matchesTable;
	JTextArea resultsDisplay = new JTextArea();
	JScrollPane pane = new JScrollPane(); 

	public SmartNotes(final int max) {
		matches = new Matches(3);//change back to max later
		matches.add(new Match(new Record("testing..."), 0.1));
		matches.add(new Match(new Record("swing"), 0.8));
		matches.add(new Match(new Record("is"), 0.7));
		matches.add(new Match(new Record("annoying"), 0.66));
		searchInput.setColumns(25);
		jPanel.add(searchInput);
		jPanel.add(searchButton);
		pane.add(new JSplitPane());
		matchesTable = new JTable(new MatchesTable(matches));
		matchesTable.setSize(400, 400);
		matchesTable.setFillsViewportHeight(true);
		matchesTable.getColumnName(0);
		matchesTable.getColumnName(1);

		resultsDisplay.setColumns(30);
		resultsDisplay.setText("test");
		jPanel.add(matchesTable);
		jPanel.add(resultsDisplay);
		getRootPane().setDefaultButton(searchButton);
		searchButton.addActionListener(new ActionListener(){ 
			public void actionPerformed(ActionEvent e){ 
				recordReader.find(searchInput.getText(), max);
				matchesTable = new JTable(new MatchesTable(matches));
			}
		});
		jPanel.setVisible(true);
	}
	public static void main(String args[]) {
		SmartNotes smartNotes = new SmartNotes(10);
		JFrame frame = new JFrame();
		frame.getContentPane().add(jPanel);
		frame.setSize(400, 500);
		frame.setVisible(true);
	}
}

I realise that SmartNotes.java isn't quite correct, but I had to add some data to the table before it would display anything.

And it looks like this when I run SmartNotes.java:



My main issue is that the table doesn't have column headers, so when the table is empty nothing shows.

Thanks so much for any help you can give me :)

Could you post Matches.java and Match.java. This would help to debug the issue
