JTextField to extend to end of JPanel

[Mike Ditka]

I'm adding several JButtons to a JPanel with a horizontal FlowLayout, then
adding a JTextField. I want the JTextField to take up all the space in the
JPanel not used by the JButtons. If the window is resized so that the panel
gets longer or shorter, I want the JTextField to be adjusted accordingly.

How can I build a horizontal panel with buttons and a text field at the end,
so that the text field takes up the remainder of the panel?

Thanks,
Mike

Mike:

See the code below for one way to get what you want. Your Buttons go on
one Panel with a FlowLayout and the Panel and your TextArea or Field go
in the center area of a BorderLayout. The BorderLayout will expand the
size of the center area when the window is resized.

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

public class test3 extends Frame {
public test3() {
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
System.exit(0);
}
});
setLayout(new BorderLayout());

Panel p = new Panel();
p.setLayout(new FlowLayout());

Button b = new Button("Button1");
p.add(b);

b = new Button("Button2");
p.add(b);

add(p,BorderLayout.WEST);

TextArea ta = new TextArea("TextArea",5,20);
add(ta,BorderLayout.CENTER);

pack();
setVisible(true);
}

public static void main(String[] args) {
new test3();
}
}

Try looking at the GridBagLayout (also GridBagConstraints). These will
allow you to assign proportions to individual elements.
