I am trying line up a single column of several buttons on the left
(West) side of a container but have not been successful. Here is a
simple code example to illustrate how I am attempting this:

import java.awt.*;

public class Vertical extends Frame {

   public static void main(String argv[]) {
       new Vertical().show();
   }

   public Vertical() {
       Button btn;
       GridBagLayout gridbag = new GridBagLayout();
       setLayout(gridbag);

       GridBagConstraints constraints = new GridBagConstraints();
       constraints.gridx = 0;
       constraints.gridy = GridBagConstraints.RELATIVE;
       constraints.anchor = GridBagConstraints.WEST;

       for (int n = 1; n <= 8; n++) {
           btn = new Button("Button " + n);
           add(btn);
           gridbag.setConstraints(btn, constraints);
       }

       resize(300, 300);
   }
}

When run the buttons are lined up in the center of the Frame. Any
ideas how to anchor the buttons on the left?
