Tekstområde til Instant messenger program

Hvad mener du?

Du kan da bare lave en JTextfield og så sætte det til not editable...

prøv at kigge lidt på det her:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class TestKlasseSwing extends JFrame implements WindowListener, Runnable
{
    private int frameWidth = 640;
    private int frameHeight = 480;
    private JScrollPane jsp;
    private JTextArea jta;
    private Thread thread;

    public TestKlasseSwing()
    {
        createFrame();
        thread = new Thread(this);
        thread.start();
    }

    private void createFrame()
    {
        setTitle("TestKlasseSwing");
        setResizable(false);
        addWindowListener(this);           
        //Place components here:
        jta = new JTextArea();
        jta.setEditable(false);
        jsp = new JScrollPane(jta);
        this.getContentPane().add(jsp);
       
        //Center Frame
        java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
        setSize(new java.awt.Dimension(frameWidth, frameHeight));
        setLocation( (screenSize.width-this.getWidth()) / 2, (screenSize.height - this.getHeight()) / 2);
    }

    public void run()
    {
        while(true)
        {
            jta.append("Jeg chatter med mig selv.\n");
            try
            {
                thread.sleep(300);
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
        }
    }

    public void windowOpened(WindowEvent e){}
    public void windowClosing(WindowEvent e){ dispose(); System.exit(0);}
    public void windowClosed(WindowEvent e){}
    public void windowIconified(WindowEvent e){}
    public void windowDeiconified(WindowEvent e){}
    public void windowActivated(WindowEvent e){}
    public void windowDeactivated(WindowEvent e){}
}

class Main
{
    public static void main(String args[])
    {
          new TestKlasseSwing().show();
    }
}

Ups... javax.swing.JTextArea og så lave en

public void setEditable(boolean b)

på den
