JTable/TableCellRenderer

jehudi

Sorry to write in English.

I render all the cells (when the mouse gets clicken etc.) in a JTable using a TableCellRenderer.  But I need also to render the cells, when another button is clicked (so that there is some change on the JTable), does anybody know how to add the Listener?

Thanks in advance.

You can just add an ActionListener to the button.

The problem is:

...

class CrossTableCellRenderer extends DefaultTableCellRenderer {

        private Color c1 = new Color(160, 160, 255);
        private Color c2 = new Color(255, 160, 160);
        private Color c3 = new Color(255, 255, 255);

        private int row_;
        private int col_;

        public Component getTableCellRendererComponent(JTable t, Object v, boolean s, boolean f, int r, int c) {
                Component cell = super.getTableCellRendererComponent(t, v, s, f, r, c);

                if (s || f) {
                        row_ = r;
                        col_ = c;
                        cell.setBackground(c2);
                }
                else {
                        if (r == row_ || c == col_)
                                cell.setBackground(c1);
                        else
                                cell.setBackground(c3);
                   }

                return cell;
        }
}

...

public void actionPerformed(ActionEvent e) {
               
                String cmd = e.getActionCommand();

                if (cmd.equals("global pivoting")) {
                        mat.set_global();    // do some operation
                        table.repaint();
                }
...

If I click the "global pivoting" button, and the JTable table will be drawed, but in
the renderer the variables s (for selected) and f (for focus) do not change.

Could you give some advices in details.
Thanks a lot.

I would like to pay RMB 100 (I am afraid only to be able to do this by cash order, "hui kuan", this is a mtter of trust) for any clue that works for me or a full repair on my code, to get my code, give me an email adress.

Thanks.

是想让JTable 的绘制器响应事件吗？如果我没记错，这是不可能的，因为绘制器本身就鉴听事件，我以前是专门从事Swing控件开发的，在我的记忆中是这个样子。
