JCheckBox in table header

Question

Hi,
I have a JTable, and I would like to put a JCheckBox in one of the columns table headers. I have searched the forums, and I believe I need to have an editor and renderer (i think)...and I have seen links that ref. examples (such as http://www2.gol.com/users/tame/swing/examples/JTableExamples9.html but they don't work anymore.
can someone help explain how I would put a checkbox in the header? I understand the renderers and editors (for the most part)...but how do i put them on table header??
thanks

Answer 1

Here is what I have now....but if i click semi-quickly on the column header...its like it doesn't catch the event in time. I can click on a regular checkbox as fast as I want, and it obviously catches my clicks..b/c i can see it check/uncheck over and over. Is there some way to make this work better, act smoother?
public class MyCheckBoxHeader extends JCheckBox implements TableCellRenderer, MouseListener {
    private boolean mouseClicked;
    private int currentColumn;
    public MyCheckBoxHeader(JTable table) {
        setHorizontalAlignment(SwingConstants.CENTER);
        JTableHeader tableHeader = table.getTableHeader();
        setBackground(tableHeader.getBackground());
        setForeground(tableHeader.getForeground());
        tableHeader.addMouseListener(this);
    /* (non-Javadoc)
     * @see javax.swing.table.TableCellRenderer#getTableCellRendererComponent(javax.swing.JTable, java.lang.Object, boolean, boolean, int, int)
    public Component getTableCellRendererComponent(
            JTable table,
            Object value,
            boolean isSelected,
            boolean hasFocus,
            int row,
            int column) {
        currentColumn = column;
        return this;
     * Had to implement this so the cell would have the same border
     * as the rest of the JTableHeader cells
    /* (non-Javadoc)
     * @see javax.swing.JComponent#paintBorder(java.awt.Graphics)
    protected void paintBorder(Graphics g) {
        g.setColor(Color.WHITE);
        // top
        g.drawLine(0, 0, getWidth(), 0);
        // left
        g.drawLine(0, 0, 0, getHeight());
        g.setColor(Color.BLACK);
        // right
        g.fillRect(getWidth() - 1, 0, 2, getHeight());
        // bottom
        g.fillRect(0, getHeight() - 1, getWidth(), getHeight());
     * Calls doClick(), because the CheckBox doesn't receive any
     * mouseevents itself. (because it is in a CellRendererPane).
   protected void handleClickEvent(MouseEvent e) {
       JTableHeader header = (JTableHeader)(e.getSource());
       JTable tableView = header.getTable();
       TableColumnModel columnModel = tableView.getColumnModel();
       int viewColumn = columnModel.getColumnIndexAtX(e.getX());
       int column = tableView.convertColumnIndexToModel(viewColumn);
       if (viewColumn == currentColumn && e.getClickCount() == 1) {
           doClick();
           repaint();
           int rowCount = tableView.getRowCount();
           for (int i = 0; i < rowCount; i++) {
               tableView.getModel().setValueAt(new Boolean(isSelected()), i, 0);
   public void mouseClicked(MouseEvent e) {
       handleClickEvent(e);
       // repaint the header to make sure the check is shown in the checkbox
       ((JTableHeader)e.getSource()).revalidate();
   public void mousePressed(MouseEvent e) {
   public void mouseReleased(MouseEvent e) {
   public void mouseEntered(MouseEvent e) {
       setCursor(Cursor.getDefaultCursor());
   public void mouseExited(MouseEvent e) {
}any suggestions would be helpful...thanks
