GridbagLayout help needed (this time with code tags :-) )

[Kristof Camelbeke]

I have the following layout : (T= Textfield)

 
TTTTTTTTT          TT
TTTTTTTTTTTTTTTTTT 
TTTTTTTTTTTTTTTTTT
TTTTTTTTT          TT
TTTTTTTTT          TT
TTTTTTTTT          TT
TTTTTTTTT          TT

The problem is I want the last Textfield of 2 positions right next to the first TextField... So I want something like this :

 
TTTTTTTTT TT
TTTTTTTTTTTTTTTTTT 
TTTTTTTTTTTTTTTTTT
TTTTTTTTT TT
TTTTTTTTT TT
TTTTTTTTT TT
TTTTTTTTT TT

Does anybody know what GridBagConstraints I have to use to achieve this. I just can't seem to place the TextFields with 2 positions after the first TextField.... Thanks for any reply...

Just so I'm understanding this correctly, you've got a long and then a short text field on the first line, then a single, long text field on each of the next two lines, followed by long and short text fields on the next lines?
To do this, you'd probably be best off creating nested panels. So, the top line with two text fields would be a single panel which could be added to the top row in the GridBag. Then the second and third lines could be added just by adding the longer text field, then new panels added for the remaining rows.
Either that, or create a table with seven rows and two columns, and set the gridwidth to be two for the second and third rows, and gridwidth to be one for the other rows. I think that would work also...
Hope this helps.

Here it is with GridBagLayout:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TestLayout extends JFrame {
public TestLayout() {
   JTextField tf1 = new JTextField(14);
   JTextField tf2 = new JTextField(2);
   JTextField tf3 = new JTextField(17);
   JTextField tf4 = new JTextField(17);
   JTextField tf5 = new JTextField(14);
   JTextField tf6 = new JTextField(2);
   
   Container contentPane = getContentPane();
   GridBagLayout gridbag = new GridBagLayout();
   GridBagConstraints c = new GridBagConstraints();
   
   JPanel panel = new JPanel();
   panel.setLayout(gridbag);
   
   getContentPane().setLayout(new FlowLayout(FlowLayout.LEFT));
   
   c.fill = GridBagConstraints.NONE;
   c.weightx = 1;
   c.anchor = GridBagConstraints.WEST;
   c.insets = new Insets(0,10,0,0);
      
   panel.add(tf1);
   
   c.gridwidth = GridBagConstraints.REMAINDER;
   gridbag.setConstraints(tf2, c);
   panel.add(tf2);
   
   c.insets = new Insets(0,0,0,0);
   c.weightx = 2;
   c.gridwidth = GridBagConstraints.REMAINDER;
   gridbag.setConstraints(tf3, c);
   panel.add(tf3);
   
   c.gridwidth = GridBagConstraints.REMAINDER;
   gridbag.setConstraints(tf4, c);
   panel.add(tf4);
   
   c.fill = GridBagConstraints.NONE;
   c.insets = new Insets(0,10,0,0);
   c.weightx = 1;
   panel.add(tf5);
   
   c.gridwidth = GridBagConstraints.REMAINDER;
   gridbag.setConstraints(tf6, c);
   panel.add(tf6);
   
   getContentPane().add(panel);
}
public static void main(String args[]) {
TestLayout window = new TestLayout();
window.setTitle("GridBagLayout");
window.setSize(800, 600);
//window.pack();
window.setVisible(true);
}
}
