Repaint() not repainting in JComponent

Question

This code doesn't repaint itself when one of the methods to reposition the label is called (eg labelLeft()). I could really do with knowing why not.
<code>
import javax.swing.*;
import javax.swing.table.*;
import vdt.*;
import java.awt.*;
public class PreviewLabel extends JComponent{
JTable table;
Object[] label = {"Account ID","Accounts","MoreAccounts"};
Object[] columns = {label};
String[] columnNames1 = {"Label"};
JLabel icon;
Icon ico;
GridBagLayout gridbag;
GridBagConstraints c;
public PreviewLabel(Icon ico) {
super();
this.ico = ico;
icon = new JLabel(ico);
table = new JTable(new MyTableModel(columns,columnNames1));
gridbag = new GridBagLayout();
c = new GridBagConstraints();
setLayout(gridbag);
c.fill = GridBagConstraints.BOTH;
c.weightx = 1.0;
protected void setup(JComponent comp,
GridBagLayout gridbag,
GridBagConstraints c) {
gridbag.setConstraints(comp, c);
add(comp);
System.out.println(comp);
public Icon getIcon(){
return ico;
public void setIcon(Icon icon){
this.ico = icon;
public void labelLeft(){
this.removeAll();
setup(icon, gridbag, c);
c.gridwidth = GridBagConstraints.REMAINDER; //end row
setup(table, gridbag, c);
public void labelTop(){
this.removeAll();
c.gridwidth = GridBagConstraints.REMAINDER; //end row
setup(icon, gridbag, c);
setup(table, gridbag, c);
public void labelBottom(){
this.removeAll();
c.gridwidth = GridBagConstraints.REMAINDER; //end row
setup(table, gridbag, c);
setup(icon, gridbag, c);
repaintAll();
public void labelRight(){
this.removeAll();
setup(table, gridbag, c);
c.gridwidth = GridBagConstraints.REMAINDER; //end row
setup(icon, gridbag, c);
</code>

Answer 1

I think you should try
invalidate()
validate()
rather than repaintAll();
When you invalidate() this calls the specific layout manager to redo the layout of the components
