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