How to add components with relative X and Y Coordinates in Java?

Java 8Object Oriented ProgrammingProgramming

To add components with relative X and Y coordinates, you need to set both the gridx and gridy components −

GridBagConstraints constraints = new GridBagConstraints();
constraints.gridy = GridBagConstraints.RELATIVE;
constraints.gridx = GridBagConstraints.RELATIVE;

The following is an example to add components with relative X and Y Coordinates −

Example

package my;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SwingDemo {
   public static void main(String[] args) {
      JFrame frame = new JFrame();
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      JPanel panel = new JPanel();
      panel.setLayout(new GridBagLayout());
      GridBagConstraints constraints = new GridBagConstraints();
      constraints.gridx = 1;
      constraints.gridy = GridBagConstraints.RELATIVE;
      panel.add(new JButton("1st row 1st column"), constraints);
      panel.add(new JButton("2nd row"), constraints);
      panel.add(new JButton("3rd row"), constraints);
      constraints.gridx = GridBagConstraints.RELATIVE;
      panel.add(new JButton("1st row 2nd column"), constraints);
      panel.add(new JButton("1st row 3rd column"), constraints);
      frame.add(panel);
      frame.setSize(550, 300);
      frame.setVisible(true);
   }
}
