JFrame layout help

Question

Hi!
I cant find any layout that fits me...
I want to set a layout on a JFrame so that every component I place on the frame will be placed in a vertical line. The components also have to be as far up as possible (not like GridLayout) and to the left.
Thanks!

Hi, now I get the layout. But it gets very small. Why is this?
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.BoxLayout;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTree;
public class TestCheckboxTree extends JFrame
     public TestCheckboxTree()
          super("Testing Checkboxes on JTree!");
          JScrollPane scrollpane = new JScrollPane();
          scrollpane.setPreferredSize(new Dimension(300, 300));
          scrollpane.setAlignmentX(LEFT_ALIGNMENT);
          JPanel panel = new JPanel();
          panel.setBackground(Color.WHITE);
          panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
          JTree tree = CheckboxTree.makeCheckTree(new FolderTree("/home/"));
          JTree tree2 = CheckboxTree.makeCheckTree(new FolderTree("/home/rejeep/programming"));
          panel.add(tree);
          panel.add(tree2);
          scrollpane.getViewport().add(panel);
          add(scrollpane);
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          setSize(500, 500);
          setVisible(true);
     public static void main(String args[])
          new TestCheckboxTree();
}
