GridBagLayout links oben platzieren!

[JLearner]

Also gut:

public class FrameForm
extends ChildFrame implements ActionListener
{

public JTextArea txtComment;
public JTextField txtID;
public int intCurrIndex=0;
GridBagLayout gbl;

public FrameForm(String strTitle)
  {
   super(strTitle);
   cp.setBackground(Color.WHITE);
   gbl = new GridBagLayout();
  new LookFeel(this);
  }

public void init() {
 //Initialisiert Layout

final int LABELHEIGHT=1;
 final int LABELWIDTH=40;

place(new JLabel("ID"),0,0,LABELWIDTH,LABELHEIGHT,1,1,20);
        place(txtID = new JTextField(),0,1,FIELDWIDTH,FIELDHEIGHT,1,1,80);

//... und so weitere Felder...

***************************************************

public class ChildFrame
 extends JInternalFrame
 {

public Container cp;
 public GridBagLayout gbl;
 public GridBagConstraints gbc;

public ChildFrame(String strTitle)
  {
   super(strTitle);
   cp = this.getContentPane();
   gbl = new GridBagLayout();
   gbc = new GridBagConstraints();
   setIconifiable(true);
   setMaximizable(true);
   setResizable(true);
        setClosable(true);
        setDefaultCloseOperation(JInternalFrame.DISPOSE_ON_CLOSE);
  }

public void place(JComponent comp, int row, int col, int width,int height)
 {
  place(comp,row,col,width,height,1,1,0);
    }

public void place(JComponent comp, int row, int col, int width,int height,int rowspan,int colspan,int weightx)
 {
  cp.setLayout(gbl);
  gbc.gridy = row;
  gbc.gridx = col;
  gbc.gridwidth = colspan;
  gbc.gridheight = rowspan;
  gbc.ipadx = width;
  gbc.ipady = height;
  gbc.anchor = GridBagConstraints.WEST;
  gbc.insets = new Insets(1,3,1,1);
  gbc.weightx = weightx;
  gbc.fill = GridBagConstraints.BOTH;
  gbl.setConstraints(comp,gbc);
  cp.add(comp);
     }

public void init(){ }
 }

So sieht das aus..aber alle Felder werden beim vergrössern zentriert. Die Frage ist wie ich das JGridBagLayout im JInternalFrame links oben platzieren kann...?
