This code is taken directly from the jdk1.2 specification.
It works fine.
import java.awt.*;
import java.util.*;
import java.applet.Applet;
public class GridBagEx1 extends Applet {
protected void makebutton(String name,
GridBagLayout gridbag,
GridBagConstraints c) {
Button button = new Button(name);
gridbag.setConstraints(button, c);
public void init() {
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints c = new GridBagConstraints();
setFont(new Font("Helvetica", Font.PLAIN, 14));
c.fill = GridBagConstraints.BOTH;
c.weightx = 1.0;
makebutton("Button1", gridbag, c);
makebutton("Button2", gridbag, c);
makebutton("Button3", gridbag, c);
c.gridwidth = GridBagConstraints.REMAINDER; //end row
makebutton("Button4", gridbag, c);
c.weightx = 0.0; //reset to the default
makebutton("Button5", gridbag, c); //another row
c.gridwidth = GridBagConstraints.RELATIVE; //next-to-last in row
makebutton("Button6", gridbag, c);
c.gridwidth = GridBagConstraints.REMAINDER; //end row
makebutton("Button7", gridbag, c);
// @@@@@from here
c.gridwidth = 1;
c.gridheight = 2;
c.weighty = 1.0;
makebutton("Button8", gridbag, c);
c.weighty = 0.0;
c.gridwidth = GridBagConstraints.REMAINDER; c.gridheight = 1;
makebutton("Button9", gridbag, c);
makebutton("Button10", gridbag, c);
// @@@@@tell here
setSize(300, 100);
public static void main(String args[]) {
Frame f = new Frame("GridBag Layout Example");
GridBagEx1 ex1 = new GridBagEx1();
f.add("Center", ex1);

If i remove the lines from /@@@@fromhere to //@@@tellhere(which are shown in the code), then the total layout is changing and also if we maximize the window the button 9 and button 10 are see very big(that is occupying entire remaining area).
So my question is i want to print all the buttons in 3 rows and 4 cols in a fixed width and height, that is in same proportion using gridbaglayout is it possible.
Please help me out in this code.

thanks in advance
It is sorta covered in the JavaRanch Style Guide.
