Problem in setting layout

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     b开发者_如何学JAVAutton2     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);
            }
        });
    }
}

There are many ways to do this, one being to further nest JPanels. Place a JPanel BorderLayout.NORTH, and give it a BorderLayout. Then add your other JPanel to this one, BorderLayout.WEST.

Border layout does not allow you to add something to NORTHWEST directly.

You might want to make the layout of the JFrame to GridBagLayout, so that you have the flexibility you want
