How to make repaint for JDialog in Swing?

How to make repaint for JDialog in Swing? If I click on convert button in JDialog I need to change GUI design of JDialog but it's not happening? Is their any solution?

    _convertAction = new AbstractAction() {
        public void actionPerformed(ActionEvent e) {
            String para = new String(); 
            _task.setBookTypeId(13);
             initComponents();
           //   validate();
           //   repaint();
            setVisible(true);
        }
      };

I'm setting booking type id is 13 .

if(_task.getBookTypeId()== 1){
    String colnames[] = {"Leg","Departure", "Date","Time", "Arrival","Date", "Time","How","Aircraft","PIC","Copilot"};
    MyTableModel mytablemodel = new MyTableModel(colnames);
    legdetailsTable = new JTable(mytablemodel);
    legdetailsTable.setRowSelectionAllowed(true);
}else {
    System.out.println("Brokered booking table");   
    String   colnames[] = {"Leg","Departure", "Date","Time", "Arrival","Date", "Time","How"};
    MyTableModel mytablemodel = new MyTableModel(colnames);
    legdetailsTable = new JTable(mytablemodel);
    legdetailsTable.setRowSelectionAllowed(true);
}

Using Id I'm changing componenents in initcomponents method.

回答1:

You can get the Window of the current Component or any Component and than call repaint().

SwingUtilities.getWindowAncestor( this ).repaint();

回答2:

Instead of

legdetailsTable = new JTable(mytablemodel);

add

legdetailsTable.setModel(mytablemodel);

You recreate JTable but the new one isn't added to layout
