Maybe create a `TableModel` and use `fireTableStructureChanged()` — giannis christofakis, Sep 23 '12 at 23:49

When you update your TableModel, the JTable should refresh itself automatically. If not, your TableModel should be corrected, for example.

The simplest way is to call .repaint() in the actionlistener. For example:

public class RefreshingButton extends JButton implements ActionListener{
    private static final long serialVersionUID = 1L;
    private final JComponent componentToRefsesh;

    public RefreshingButton(JComponent toRefresh) {
        super("Refresh JTable");
        this.componentToRefsesh = toRefresh;
        this.addActionListener(this);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        componentToRefsesh.repaint();
    }
}

The best way is to use the Model-View-Controller design pattern. http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller

AFAIK repaint are for Graphics(2D), notify LayoutManager after changes into Components Tree, the same in this for doLayout or notify – mKorbel Sep 23 '12 at 14:07

no. a) don't subclass a JSomething, instead use it b) don't expose api that's not meant for public usage (here's that the actionListener callback), instead instantiate/implement the listener internally and use it c) most of the time a repaint appears to be needed, somthing is wrong with the setup – kleopatra Sep 23 '12 at 16:00
