Question

I have made a JFrame and inside that frame, there is panel on which I have placed various containers using GridBagLayout. I have set layout of JFrame to be BorderLayout, and added panel in BorderLayout.WEST. I want to show that panel’s containers at the top left corner. How can I do that?

Even if I try to add panel to BorderLayout.NORTH then also it is displayed in top center but instead I want to be in top left corner.

Is there any way to do that? I.E. any other layout I should use as I want to show

label1
button1     button2     button3

label2
button1     button2     button3

label 3
button1     button2     button3

This is easy to do with just GridLayout and BorderLayout.

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

class LabelButtonLayout {

    public static Component getButtonLayout(int num) {
        JPanel p = new JPanel(new BorderLayout(3,3));

        p.add(new JLabel("Label " + num), BorderLayout.NORTH);

        JPanel b = new JPanel(new GridLayout(1,0,25,5));
        for (int ii=1; ii<4; ii++) {
            b.add(new JButton("Button " + ii));
        }
        p.add(b, BorderLayout.CENTER);

        return p;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater( new Runnable() {
            public void run() {
                JPanel gui = new JPanel(new GridLayout(0,1,3,15));
                for (int ii=1; ii<4; ii++) {
                    gui.add(getButtonLayout(ii));
                }
                JOptionPane.showMessageDialog(null, gui);
            }
        });
    }
}
