Where can I found examples for a gui with a big textarea and some buttons ?
Thanks.

Here's a more useful example, just in case I seem too sarcastic :-)

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

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.SwingUtilities;


public class ABigTextAreaAndSomeButtons implements ActionListener {

private static final String THIS="This", THAT="That", OTHER="Other";

private JTextArea area = new JTextArea(40,80);

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new ABigTextAreaAndSomeButtons();
}
});
}

ABigTextAreaAndSomeButtons() {
JPanel p = new JPanel();
p.setLayout(new BorderLayout());
p.add(area, BorderLayout.CENTER);
JPanel bp = new JPanel();
bp.add(makeJButton(THIS));
bp.add(makeJButton(THAT));
bp.add(makeJButton(OTHER));
p.add(bp, BorderLayout.SOUTH);

JFrame f = new JFrame("A big text area with some buttons");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(p);
f.pack();
f.setVisible(true);
}

private JButton makeJButton(String label) {
JButton b = new JButton(label);
b.addActionListener(this);
return b;
}

public void actionPerformed(ActionEvent e) {
String command = e.getActionCommand();
area.append("\n" + command);
if (OTHER.equals(command))
area.append(" **bonus** ");
}

}

I hoped your first example might have begun to make the OP
realize that perhaps they might have gone about asking that
question in a different (and more specific) way.

>...just in case I seem too sarcastic :-)

If they did not get the wider message, perhaps you were
not sarcastic enough.  ;-)

To the OP.  I read your question and was going to post
a code example like RedGrittyBrick, but since I had no
idea what you wanted in this GUI (and to be quite truthful,
I do not care deeply) I did not even bother to do that.

Further, I do not think that finding a few codes examples
as you stated, will progress your own technical problem
much (which, I am guessing, is to build a UI that has a
large text area and a few buttons).

What will help you a great deal more, in the long run,
is to understand how Java GUI's are construced using
*layouts*.  For that knowledge, I highly recommend the
layout section of the Java Tutorial.
<http://java.sun.com/docs/books/tutorial/uiswing/layout/>
<http://java.sun.com/docs/books/tuto...yout/using.html>

Note that the 'Examples Index' linked from the top
of the first page linked above, contains dozens
(from memory) of code samples.

One thing I suspect that is not covered well in those
pages, was demonstrated in RGB's second example,
which uses a 'nested layout'.  This is what I call putting
a container with one layout (The JPanel that holds the
buttons gets a FlowLayout, by default) into a larger
container with a (usually different) layout.

I posted this yesterday but it didn't show up.  This includes an example
of how to add actions to buttons and how to do a simple layout.

import java.awt.*;
import java.awt.event.*;

public class test8 extends Frame implements ActionListener {
TextArea ta;

public test8() {
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
System.exit(0);
}
});

setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.gridx = c.gridy = 0;  c.insets = new Insets(2,2,2,2);

ta = new TextArea("Hello World!\n",20,80);
Button b1 = new Button("One");
Button b2 = new Button("Two");
Button b3 = new Button("Three");

b1.addActionListener(this);
b2.addActionListener(this);
b3.addActionListener(this);

c.gridwidth = 3;
add(ta,c);

c.gridwidth = 1;  ++c.gridy;
c.weightx = 1.0;  c.anchor = GridBagConstraints.EAST;
add(b1,c);

++c.gridx;
c.weightx = 0.0;  c.anchor = GridBagConstraints.CENTER;
add(b2,c);

++c.gridx;
c.weightx = 1.0;  c.anchor = GridBagConstraints.WEST;
add(b3,c);

pack();
setVisible(true);
}

public void actionPerformed(ActionEvent ae) {
String ac = ae.getActionCommand();

if (ac.equals("One")) {
ta.append(ac + "\n");
} else if (ac.equals("Two")) {
ta.append(ac + "\n");
} else if (ac.equals("Three")) {
ta.append(ac + "\n");
}
}

public static void main(String[] args) {
new test8();
}
}
