Question

Please have a look at the following code

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class GridLayoutTest2
{
    private final JDialog msgDisplayer;
    public GridLayoutTest2()
    {
        JLabel maleLabel = new JLabel("Male",JLabel.CENTER);
            maleLabel.setBorder(BorderFactory.createEmptyBorder());
            JLabel femaleLabel = new JLabel("Female",JLabel.CENTER);
            femaleLabel.setBorder(BorderFactory.createEmptyBorder());

            JLabel fmaleIcon = new JLabel();
            fmaleIcon.setIcon(new ImageIcon(getClass().getResource("/images/TESTING-Image.gif")));
            fmaleIcon.setBorder(BorderFactory.createEmptyBorder());


            JLabel maleIcon = new JLabel();
            maleIcon.setIcon(new ImageIcon(getClass().getResource("/images/TESTING-Image.gif")));
            maleIcon.setBorder(BorderFactory.createEmptyBorder());

            msgDisplayer = new JDialog();
            msgDisplayer.setLayout(new GridLayout(4,1,1,1));
            msgDisplayer.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

            msgDisplayer.setTitle("Body Fat Percentage Classification");


            msgDisplayer.add(femaleLabel);
            msgDisplayer.add(fmaleIcon);
            msgDisplayer.add(maleLabel);
            msgDisplayer.add(maleIcon);

            msgDisplayer.pack();
            msgDisplayer.setVisible(true);
            msgDisplayer.setLocationRelativeTo(null);
    }

    public static void main(String[]args)
    {
        try
        {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
            new GridLayoutTest2();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

This code contains a HUGE gap (space) between the labels and images screenshot attached). I do not want to have this space between labels and images. How can I eliminate it? I know I can go with the GridBagLayout to do it, but, is there any way in GridLayout? Please help!

Answer 1

GridLayout allocates an equals amount of space for all components based on the largest component in the container. If you don’t wish to use a complex layout manager such as GridBagLayout, you could use BoxLayout, which uses the component’s preferred sizes. A BoxLayout with Y_AXIS alignment would be suitable here.
