JFrame not showing the whole JPanel

Question

Hi,
I have a JPanel with a few buttons on it(using flowlayout). I added the JPanel to a JFrame. I want to prevent the JFrame from resizing to a size which hides the buttons on the JPanel. Is there any way to do it without explicitly specifing the size of the JFrame. I want the JFrame to automatically see that all the components of the JPanel won't be displayed if it's size is reduced. Hence don't allow resize.

If you still want to resize larger (just not smaller) you could do something like this:
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
public class Resize {
    public static void main(String [] args) {
        JFrame f = new JFrame("Resize Test");
        JPanel p = new JPanel();
        p.add(new JButton("Button1"));
        p.add(new JButton("Button2"));
        p.add(new JButton("Button3"));
        p.add(new JButton("Button4"));
        p.add(new JButton("Button5"));
        f.getContentPane().add(p);
        f.pack();
        f.setVisible(true);
        final Dimension minSize = f.getSize();
        f.addComponentListener(new ComponentAdapter() {
            public void componentResized(ComponentEvent e) {
                Dimension d = ((JFrame) e.getSource()).getSize();
                if (d.width < minSize.width)
                    ((JFrame) e.getSource()).setSize(minSize.width, d.height);
}Matt
