OK cool thanks. Other than relying on the IDE, is there a list detailing what tags need a closing tag and which ones don't? A bit like the HTML doc type

I am finally back after quite some time, and unfortunately I have lost quite a bit of what I have learned...
Anyway, I went back through my notes and old posts and messed around with the GridBagConstraints again, and I have a few questions.
This is the latest version of a 5x1 grid of buttons (screenshot attached 
)
/*TestingGridBag.java*/
import java.awt.GridBagLayout;//chosen JFrame layout
import static java.awt.GridBagConstraints.*;
import java.awt.GridBagConstraints;
import java.awt.Insets;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JButton;//for radio buttons
public class TestingGridBag extends JFrame{
private GridBagLayout layout;
//private JPanel panel;
private JButton okButton;
private JButton cancelButton;
private JButton submitButton;
private JButton test1Button;
private JButton test2Button;
public TestingGridBag(){
super("GridBagLayout test");
layout = new GridBagLayout();
setLayout( layout );//set layout of JFrame
//panel = new JPanel();
okButton = new JButton("OK");
cancelButton = new JButton("Cancel");
submitButton = new JButton("Submit");
test1Button = new JButton("test1");
test2Button = new JButton("test2");
add( okButton, new GridBagConstraints( 0, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 20), 0, 0 ) );
add( cancelButton, new GridBagConstraints( 2, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 20), 0, 0 ) );
add( submitButton, new GridBagConstraints( 4, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 20), 0, 0 ) );
add( test1Button, new GridBagConstraints( 6, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 20), 0, 0 ) );
add( test2Button, new GridBagConstraints( 8, 0, 1, 1, 0, 0, CENTER, NONE, … Violet_82 89 Posting Whiz in Training
Right, another question.
Just to pick up on something said before about a cell being empty in the layout:
Not that I know of. Just don't put anything in it!
SOmetimes I have had dynamic form contents where I have (eg) added buttons at 1,0 2.0 and 999,0 so I can later add buttons after the first two, but before the last one. The unused columns just get a zero width.
I thought I'd replicate this layout now:
So I changed my code accordingly:
add( okButton, new GridBagConstraints( 0, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 0), 0, 0 ) );
add( cancelButton, new GridBagConstraints( 2, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 0), 0, 0 ) );
add( submitButton, new GridBagConstraints( 4, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 0), 0, 0 ) );
add( test1Button, new GridBagConstraints( 6, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 0), 0, 0 ) );
add( test2Button, new GridBagConstraints( 8, 0, 1, 1, 0, 0, CENTER, NONE, new Insets( 0, 0, 0, 0), 0, 0 ) );
I have modified the coordinates in an attempt to produce an empty cell between the buttons, but nothing gets displayed. Now, I assume this happens because, as it has been pointed out before, the width of an empty column (and in this case having only one row the empty cell effectively represents a column) is 0. So how do I get around this? SHould I use the inset values perhaps?
thanks
