Help with Gridbag Layout

[gaz123]

I realise this is probably something simple, but here goes. I'm a home-taught student and have been set the task of creating a GUI and engine for a game. My engine works fine, as did my GUI before my tutor told me he doesn't want me to do the UI as I had but instead wants it done using Gridbag. After a few hours of struggling with tutorials, I've written part of the GUI and checked it only to find it was all over the place. I asked my tutor for help, the response was simply "use an internet forum or a tutorial, you'll learn more because you'll have to work through it". Yes, I know he's a bad tutor but since it's my parents that decide these things I can't say much (apparently my dad worked with him years ago). However, I would appreciate some help fixing what I've done.

The GUI should look something like this: -

--------------------------------------------------------
---------------------------NIM-----------------------
--------------------------------------------------------
---Computer---[=]--*----*--[=]----Player----
--------------------------------------------------------
----------------------[End Turn]-------------------

(Sorry for the terrible psudo-image)

Instead I end up with everything overlapping. This is probably because I'm trying to convert my former UI into gridbag.

[code=java]
import java.awt.*;
import java.awt.event. *;
import java.io.*;
import javax.sound.sam pled.*;
import javax.swing.*;

public class UI extends JFrame
{
GridBagLayout gbl;

public UI ()
{
super ("NIM");

setDefaultClose Operation (EXIT_ON_CLOSE) ;

getContentPane ().add (buildGUI ());

pack ();

setVisible (true);
}

public JPanel buildGUI ()
{
JPanel panel = new JPanel (gbl = new GridBagLayout ());
GridBagConstrai nts gbc = new GridBagConstrai nts ();

JLabel lblTitle = new JLabel ("NIM");

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 0;
gbc.gridy = 0;
gbc.gridwidth = 6;
gbc.anchor = GridBagConstrai nts.PAGE_START;
panel.add (lblTitle, gbc);


JLabel lblComputer = new JLabel ("Computer") ;
JTextField txtComputer = new JTextField (2);
lblComputer.set LabelFor (txtComputer);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 0;
gbc.gridy = 1;
panel.add (lblComputer, gbc);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 1;
gbc.gridy = 1;
panel.add (txtComputer, gbc);


JLabel lblScoreCPU = new JLabel ("*");
JLabel lblScorePLY = new JLabel ("*");

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 1;
gbc.gridy = 2;
panel.add (lblScoreCPU, gbc);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 1;
gbc.gridy = 3;
panel.add (lblScorePLY, gbc);


JLabel lblPlayer = new JLabel ("Player");
JTextField txtPlayer = new JTextField (2);
lblPlayer.setLa belFor (txtPlayer);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 4;
gbc.gridy = 1;
panel.add (txtPlayer, gbc);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 5;
gbc.gridy = 1;
panel.add (lblPlayer, gbc);


JButton btnEnd = new JButton ("End Turn");
Dimension size = btnEnd.getPrefe rredSize ();
size.width = 100;
btnEnd.setPrefe rredSize (size);

gbc.fill = GridBagConstrai nts.HORIZONTAL;
gbc.weightx = 0.5;
gbc.gridx = 0;
gbc.gridy = 2;
gbc.gridwidth = 6;
panel.add (btnEnd, gbc);

return panel;
}


public static void main (String [] args)
{
new UI ();
}
}
[/code]

(The rest of the code is "yet to be converted", mainly involes the engine and a drag-drop area)

If anyone can help, that'd be great. Thanks.

Have you gone through the GridBagLayout tutorial?

Have you gone through the GridBagLayout tutorial?

Yes, I thought I mentioned in the origional post I had. I've gone through several different tutorials.

Is nobody able to see what I've done wrong? I need to get this finished over the weekend, please help.
