Adding Text from button to text field.

[Irish Rayray]

Hi All,

This is my code so far.

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

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

public class NestedLayoutsLab extends JFrame implements ActionListener{
	
	private JPanel masterPanel = new JPanel(new BorderLayout());
	private JPanel minorPanel = new JPanel(new GridLayout(4, 2));
	
	private JButton Clear = new JButton("CE");
	private JButton Dot = new JButton(".");
	private JButton Zero = new JButton("0");
	private JButton One = new JButton("1");
	private JButton Two = new JButton("2");
	private JButton Three = new JButton("3");
	private JButton Four = new JButton("4");
	private JButton Five = new JButton("5");
	private JButton Six = new JButton("6");
	private JButton Seven = new JButton("7");
	private JButton Eight = new JButton("8");
	private JButton Nine = new JButton("9");
	

	private JTextField theNorthLabel = new JTextField("No Input Entered");

	public NestedLayoutsLab(String aStr){
		super(aStr);
		
		Clear.addActionListener(this);
		Dot.addActionListener(this);
		Zero.addActionListener(this);
		One.addActionListener(this);
		Two.addActionListener(this);
		Three.addActionListener(this);
		Four.addActionListener(this);
		Five.addActionListener(this);
		Six.addActionListener(this);
		Seven.addActionListener(this);
		Eight.addActionListener(this);
		Nine.addActionListener(this);
		
		masterPanel.add(theNorthLabel, BorderLayout.NORTH);
		
		minorPanel.add(Nine);
		minorPanel.add(Eight);
		minorPanel.add(Seven);
		minorPanel.add(Six);
		minorPanel.add(Five);
		minorPanel.add(Four);
		minorPanel.add(Three);
		minorPanel.add(Two);
		minorPanel.add(One);
		minorPanel.add(Zero);
		minorPanel.add(Dot);
		minorPanel.add(Clear);		
		
		theNorthLabel.setHorizontalAlignment(JLabel.CENTER);
		
		masterPanel.add(minorPanel);
		getContentPane().add(masterPanel);

        setSize(350,200);
		setVisible(true);
	}
	
	public void actionPerformed(ActionEvent e) {
		if(e.getSource().equals(Nine)){
			theNorthLabel.setText("9");
		}else if(e.getSource().equals(Eight)){
			theNorthLabel.setText("8");
		}else if(e.getSource().equals(Seven)){
			theNorthLabel.setText("7");
		}else if(e.getSource().equals(Six)){
			theNorthLabel.setText("6");
		}else if(e.getSource().equals(Five)){
			theNorthLabel.setText("5");
		}else if(e.getSource().equals(Four)){
			theNorthLabel.setText("4");
		}else if(e.getSource().equals(Three)){
			theNorthLabel.setText("3");
		}else if(e.getSource().equals(Two)){
			theNorthLabel.setText("2");
		}else if(e.getSource().equals(One)){
			theNorthLabel.setText("1");
		}else if(e.getSource().equals(Zero)){
			theNorthLabel.setText("0");
		}else if(e.getSource().equals(Dot)){
			theNorthLabel.setText(".");
		}else if(e.getSource().equals(Clear)){
			theNorthLabel.setText("");
		}
	}	
	public static void main(String[] args){
		new NestedLayoutsLab("Border Layout");
	}
}

What I'm trying to so is when you click a button instead of setting the Field to = the button i want to add the digit to the field.
I'm still looking into this and if i figure it out i will post my solution but some help would be appropriated as it may help speed up things.

Thank you.

theNorthLabel.setText(theNorthLabel.getText()+ "0");

Moved from Advanced Java. Not in any way an advanced question either.
